MOLECULAR ANTIGEN ARRAYS BACKGROUND OF THE INVENTION Field of the Invention The present invention is in the fields of medicine, immunology, virology and molecular biology. Related Art Vaccination has provided one of the most effective ways of fighting infectious diseases and has led to the most significant benefits for public health in the last century. Early vaccination strategies used live, attenuated or inactivated pathogens as the immunogen. Safety concerns within the public and the authorities have fostered a search for more defined and safer vaccines. This search stimulated anew direction of research, where individual antigens were isolated or recombinantly expressed and injected as immunogens. Examples of these include the development and use of subunit vaccines. Such vaccines, however, often require the addition of an adjuvant to generate a sufficient immune response against the antigen, as an isolated protein is typically not sufficiently immunogenic to generate a protective immune response. Although several strong adjuvants are known, such as complete Freund's adjuvant, they are generally toxic and cannot be used in humans. Great efforts are therefore being made in the search for new adjuvants. Recently, research on the principles of discrimination by the immune system between self and foreign has revealed that the degree of organization and the repetitiveness of the antigens on the surfaces of viruses are a very strong signal for an antigen to be recognized as foreign (Bachmann & Zinkernagel, Immunol. Today 17:553-558 (1996)). This property of viral structures was made use of in the design of new vaccines based on virus-like particles (VLPs), which combined the immunogenicity of viral structures and the improved safety profile of non-replicable vaccines. In those vaccines, the antigen is either fused or chemically attached to viruslike particles, the chemical attachment being covalent or non-covalent. Thus, the immunogenic property of the viral structure is transferred to the antigen by linking the antigen to virus-like particles. A variety of VLPs have been used for the attachment of antigens. For example, WO 00/32227 describes the use of Hepatitis B core antigen in the production of certain types of vaccines. A new class of highly expressable and highly immunogenic VLPs has been disclosed in WO 03/056905, which is incorporated herein by reference in its entirety. These VLPs are composed of the coat protein of RNA bacteriophages. The coat proteins are expressed recombinantly in bacteria, and the VLP does not contain the phage RNA genome and therefore cannot replicate. A new RNA bacteriophage, AP205, has been recently identified (KlovinsJ., et al, J. Gen. Virol. 83: 1523-33 (2002).) The AP205 RNA phage (Taxonomy ID: 154784) is a single-stranded, positive-strand RNA (no DNA stage) virus, which belongs to the Leviviridae family, Levivirus genus, Unclassified Levivirus subgroup. The other members of this subgroup are RNA phages BOl, frl, TW19, andPP7. Two described Levivirus subgroups include following RNA phages: fr, JP501, f2, M12, MS2, and R17 (subgroup I) and BZ13, JP34, TH1, GA, and K.U1 (subgroup II). The AP205 genome is 4267 nucleotides (nt) in length. Full-length genomic sequence: accessions AF334111, NC_002700. The natural host of the AP205 phage is Acinetobacterspp.(Klovins,J.,et al.,J. Gen. Virol 83:1523-33 (2002)). The genome of the AP205 phage comprises three large open reading frames (ORFs), which code for the maturation, the coat and the replicase proteins. In addition, two additional small ORFs are present at the 5' terminus, preceding the maturation gene. The function of the proteins coded by these ORFs is unknown. It has been postulated that one of these ORFs might code for a lysis protein (Klovins,J., et al, J. Gen. Virol 83: 1523-33 (2002)). SUMMARY OF THE INVENTION We have discovered that AP205 coat protein can be recombinantly expressed in bacteria using the vectors of the invention. We have also developed methods for purification of AP205 virus-like particles. Moreover, the AP205 coat proteins produced by the present method spontaneously formed capsids, as evidenced by Electron Microscopy (EM) and immunodifiusion, and therefore the coat protein alone together with RNA are sufficient for assembly of the capsid in E. coli. This rules out any role of the proteins coded by the two ORFs of unknown function. A surprising feature of the invention is that no sequence homology exists between the sequence of the AP205 coat protein and other RNA phage coat proteins from which the structure has been elucidated, yet the structural properties of the capsid formed by the AP205 coat protein and those formed by the coat protein of those RNA phages are nearly indistinguishable when seen in EM. We have discovered that AP205 VLPs are highly immunogenic, and can be linked with organic molecules to generate vaccine constructs displaying the organic molecules oriented in a repetitive manner. High titers were elicited against the so displayed organic molecules showing that bound organic molecules are accessible for interacting with antibody molecules and are immunogenic. The present invention provides recombinantly expressed virus-like particles (VLPs), spontaneously assembled from at least one coat protein of bacteriophage AP205 recombinantly expressed in E. coli. In a related aspect, the invention provides assembly-competent mutant forms of AP205 VLPs, including AP205 coat protein with the substitution of proline at amino acid 5 to threonine (SEQ ID NO: 3). These VLPs, AP205 VLPs derived from natural sources (SEQ ID NO: 1)., or AP205 viral particles, may be bound to at least one organic molecule to produce ordered repetitive arrays of the organic molecules. Organic molecules of the invention include antigens and antigen determinants, allergens, self antigens, haptens, cancer antigens and infectious disease antigens as well as small organic molecules such as drugs of abuse like nicotine and derivatives thereof. Immunisation of animals using antigen-AP205 VLP conjugates, or compositions comprising such conjugates as provided by the invention, induce a strong immune response against the displayed antigen. The VLP of the invention is thus useful for the attachment and display of molecules and in particular of antigens. Hence, the conjugates, compositions and methods of the invention are useful for the stimulation of an immune response against a variety of displayed antigens, and thus for the use in animals.

Total IgG titers were determined in the day 21 sera, DETAILED DESCRIPTION OF THE INVENTION Definitions The following definitions are summaries of concepts commonly understood by one of ordinary skill in the relevant art and are provided for the purposes of comprehension of the following disclosure but are not meant to be a limitation of the disclosure. Amino acid linker: An "amino acid linker", or also just termed "linker" within this specification, as used herein, either associates the antigen or antigenic determinant with the second attachment site, or more preferably, already comprises or contains the second attachment site, typically - but not necessarily - as one amino acid residue, preferably as a cysteine residue. The term "amino acid linker" as used herein, however, does not intend to imply that such an amino acid linker consists exclusively of amino acid residues, even if an amino acid linker consisting of amino acid residues is a preferred embodiment of the present invention. The amino acid residues of the amino acid linker are, preferably, composed of naturally occuring amino acids or unnatural amino acids known in the art, all-L or all-D or mixtures thereof. However, an amino acid linker comprising a molecule with a sulfhydryl group or cysteine residue is also encompassed within the invention. Such a molecule comprise preferably a C1-C6 alkyl-, cycloalkyl (C5,C6), aryl or heteroaryl moiety. However, in addition to an amino acid linker, a linker comprising preferably a C1-C6 alkyl-, cycloalkyl- (C5, C6), aryl-or heteroaryl- moiety and devoid of any amino acid(s) shall also be encompassed within the scope of the invention. Association between the antigen or antigenic determinant or optionally the second attachment site and the amino acid linker is preferably by way of at least one covalent bond, more preferably by way of at least one peptide bond. Animal: As used herein, the term "animal" is meant to include, for example, humans, sheep, elks, deer, mule deer, minks, mammals, monkeys, horses, cattle, pigs, goats, dogs, cats, rats, mice, birds, chicken, reptiles, fish, insects and arachnids. Antibody: As used herein, the term "antibody" refers to molecules which are capable of binding an epitope or antigenic determinant. The term is meant to include whole antibodies and antigen-binding fragments thereof, including single-chain antibodies. Such antibodies include human antigen binding antibody fragments and include, but are not limited to, Fab, Fab' and F(ab')2, Fd, single-chain Fvs (scFv), single-chain antibodies, disulfide-linked Fvs (sdFv) and fragments comprising either a VL or VH domain. The antibodies can be from any animal origin including birds and mammals. Preferably, the antibodies are mammalian e.g. human, murine, rabbit, goat, guinea pig, camel, horse and the like, or other suitable animals e.g. chicken. As used herein, "human" antibodies include antibodies having the amino acid sequence of a human immunoglobulin and include antibodies isolated from human immunoglobulin libraries or from animals transgenic for one or more human immunoglobulins and that do not express endogenous immunoglobulins, as described, for example, in U.S. Patent No. 5,939,598, the disclosure of which is incorporated herein by reference in its entirety. Antigen: As used herein, the term "antigen" refers to a molecule capable of being bound by an antibody or a T cell receptor (TCR) if presented by MHC molecules. The term "antigen", as used herein, also encompasses T-cell epitopes. A T-cell epitope is recognized by a T-cell receptor in the context of a MHC class I, present on all cells of the body except erythrocytes, or class II, present on immune cells and in particular antigen presenting cells. This recognition event leads to activation of T-cells and subsequent effector mechanisms such as proliferation of the T-cells, cytokine secretion, perforin secretion etc. An antigen is additionally capable of being recognized by the immune system and/or being capable of inducing a humoral immune response and/or cellular immune response leading to the activation of B- and/or T-lymphocytes. This may, however, require that, at least in certain cases, the antigen contains or is linked to a TH cell epitope and is given in adjuvant. An antigen can have one or more epitopes (B- and T- epitopes). The specific reaction referred to above is meant to indicate that the antigen will preferably react, typically in a highly selective manner, with its corresponding antibody or TCR and not with the multitude of other antibodies or TCRs which may be evoked by other antigens. Antigens as used herein may also be mixtures of several individual antigens. Antigens, as used herein, include but are not limited to allergens, self antigens, haptens, cancer antigens and infectious disease antigens as well as small organic molecules such as drugs of abuse (like nicotine) and fragments and derivatives thereof. Furthermore, antigens used for the present invention can be peptides, proteins, domains, carbohydrates, alkaloids, lipids or small molecules such as, for example, steroid hormones and fragments and derivatives thereof Antigenic determinant: As used herein, the term "antigenic determinant" is meant to refer to that portion of an antigen that is specifically recognized by either B-or T-lymphocytes. B-lymphocytes respond to foreign antigenic determinants via antibody production, whereas T-lymphocytes are the mediator of cellular immunity. Thus, antigenic determinants or epitopes are those parts of an antigen that are recognized by antibodies, or in the context of an MHC, by T-cell receptors. An antigenic determinant contains one or more epitopes. Allergens also serve as antigens in vertebrate animals. Allergens: As used herein, the term "allergen" refers to antigens associated with allergies. An allergic response is characterized by the release of inflammatory factors, particularly histamine, leading to pathologic inflammation in an individual. Allergies are, typically, also associated with IgE antibodies directed against the allergens. The term "allergen", as used herein, also encompasses "allergen extracts" and "allergenic epitopes." Examples of allergens include, but are not limited to: pollens (e.g. grass, ragweed, birch and mountain cedar); house dust and dust mites; mammalian epidermal allergens and animal danders; mold and fungus; insect bodies and insect venom; feathers; food; and drugs (e.g., penicillin). AP205 virus-like particle or AP205 VLP: As used herein, the terms "AP205 virus-like particle" or "AP205 VLP" refer to compositions and virus-like particles, respectively, comprising, or alternatively consisting essentially of, or alternatively and preferably consisting of at least one protein and coat protein, respectively, of the bacteriophage AP205, or a fragment or a mutein thereof, wherein said at least one coat protein, or fragment or mutein thereof, is typically and preferably able to assemble forming a virus-like particle.

Vector: As used herein, the term "vector" refers to an agent (e.g., a plasmid or virus) used to transmit genetic material to a host cell. A vector may be composed of either DNA or RNA. Virus-like particle (VLP): As used herein, the term "virus-like particle" refers to a structure resembling a virus particle. Moreover, a virus-like particle in accordance with the invention is non replicative and noninfectious since it lacks all or part of the viral genome, in particular the replicative and infectious components of the viral genome. A virus-like particle in accordance with the invention may contain nucleic acid distinct from their genome. A typical and preferred embodiment of a virus-like particle in accordance with the present invention is a viral capsid such as the viral capsid of the corresponding virus, bacteriophage, or RNA-phage. The terms "viral capsid" or "capsid", as interchangeably used herein, refer to a macromolecular assembly composed of viral protein subunits. Typically and preferably, the viral protein subunits assemble into a viral capsid and capsid, respectively, having a structure with an inherent repetitive organization, wherein said structure is, typically, spherical or tubular. For example, the capsids of RNA-phages have a spherical form of icosahedral symmetry. The term "capsid-like structure" as used herein, refers to a macromolecular assembly composed of viral protein subunits ressembling the capsid morphology in the above defined sense but deviating from the typical symmetrical assembly while maintaining a sufficient degree of order and repetitiveness.

Overview We have discovered that recombinant AP205 coat proteins can be expressed in bacteria using the vectors of the invention and obtained in purified form. Recombinant AP205 coat proteins hereby spontaneously self-assemble within the bacteria into Aß 205 virus-like particles. The invention provides for host cells and vectors suitable for expression of AP205 VLPs and also assembly competent variant forms of the AP205 coat protein. These expressed VLPs, AP205 VLPs derived from natural sources, or AP205 viral particles, may be bound to organic molecules to produce ordered repetitive arrays of the organic molecules. Organic molecules of the invention include antigens, allergens, self antigens, haptens, cancer antigens and infectious disease antigens. In one embodiment, the organic molecules are polypeptides or proteins. Formation of conjugates of the invention, i.e. binding organic molecules to the VLP, is achieved by attachment, linkage, fusion or other binding, including covalent and non covalent bonds. In one embodiment, the VLP contains a first attachment site, the organic molecule contains a second attachment site. Association between the organic molecule occurs by linking the first and second attachment sites directly, or via a third molecule, typically and preferably via a cross-linker. Attachment sites may occur naturally, or may be introduced. In a preferred embodiment, the binding comprises at least one covalent bond, preferably comprises a peptide bond or alternatively and preferably comprises a non-peptide bond. Immunization of animals with AP205 VLP conjugates, or with compositions comprising such conjugates as provided by the invention, induce a strong immune response against the displayed organic molecule. Hence, the conjugates and compositions of the invention are useful for the stimulation of an immune response against a variety of displayed antigens, and thus for the use in animals. The present invention also relates to a vaccine comprising an immunologically effective amount of the composition of one or more conjuagtes of the present invention together with a pharmaceutically acceptable diluent, carrier or excipient The AP205 VLPs can be used to vaccinate against haptens, allergens, tumors, viral diseases, or self-molecules or non-peptidic small molecules, for example. The vaccination can be for prophylactic or therapeutic purposes, or both. In a related aspect immune molecules and antibodies, respectively, such as antibodies, generated against such compositions maybe used for treatment, prophalaxis or diagnosis of a disease, condition or disorder. Such antibodies, and compositions of the invention are also useful as kits. Cloning of the AP205 Bacteriophage Coat Protein The AP205 genome consists of a maturation protein, a coat protein, areplicase and two open reading frames not present in related phages; a lysis gene and an open reading frame playing a role in the translation of the maturation gene (Klovins,J., et al., J. Gen. Virol. 83: 1523-33 (2002)). In one aspect of the invention the coat protein cDNA was isolated by reverse transcription of AP205 bacteriophage RNA followed by PCR, using known methods in the art The cDNA of the coat protein including a ribosomal binding site upstream of the coat protein gene was cloned into vectorpQblO (Kozlovska, T. M.. et al, Gene 737:133-37 (1993)). In another approach the cDNA of AP205 coat protein may be cloned in vector pQbl 85, replacing the bacteriophage QP coat protein gene, and thus downstream of the ribosomal binding site present in the vector. Both approaches lead to expression of the protein and formation of capsids. Thus, in the present invention, the coat protein may be expressed from vectors containing a ribosomal binding site which is not an AP205 ribosomal binding site, such as in the pQbl85 vector. Vectors pQblO and pQbl85 are vectors derived from pGEM vector, and expression of the cloned genes in these vectors is controlled by the trp promoter (Kozlovska, T. M. et al, Gene 137:133-37 (1993)). pAP283-58 (SEQ ID No. 2) comprises a putative AP205 ribosomal binding site in the following sequence, which is downstream of the Xbal site, and immediately upstream of the ATG start codon of the (Sequence Removed) The vector pQbl85 comprises a Shine Delagarno sequence downstream from the Xbal site and upstream of the start codon (tctagaTTAACCCAACGCGTAGGAG TCAGGCCatg (SEQ ID NO: 6), Shine Delagarno sequence underlined), which is also present in vectorpAP281-32 (SEQ ID No. 4). Other vectors known to the Art include, e.g.,pKK 223.3, pET vector family, pBR322 (Sutcliffe, J.G. Cold Spring Harb. Symp. Quant. Biol 43 Pt 1: 77-90 (1979)), pUC 18, pUC19, which are all modified to comprise a suitable promoter and ribosomal binding sites if not present or not suitable for expression of the coat protein and subsequent formation of virus-like particles as would be recognized by one skilled in the art. Other vectors derived from the aforementioned vectors and other vectors suitable for expression of proteins in E. coli or other hosts known to one skilled in the art and in general any vector suitable for expression of proteins in E.coli or other hosts are suitable for practicing the invention, provided they allow expression of the coat protein and subsequent formation of viruslike particles. In one aspect of the present invention, vectors for expression of the gene of AP205 coat protein are transfected into E. coli. Suitable E. coli strains include, but are not limited to, E. coli K802, JM109, RR1. Other E. coli strains are known to one of ordinary skill in the Art, and suitable combinations of vectors and strains can be identified by testing expression of the coat protein by SDS-P AGE and capsid formation and assembly by optionally first purifying the capsids by gel filtration and subsequently testing them in an immunodiffusion assay (Ouchterlony test) or Electron Microscopy (Kozlovska, T. M.. et al, Gene 137:133-37 (1993)). AP205 coat proteins expressed from the vectors pAP283-58 and pAP281-32 may be devoid of the initial Methionine amino-acid, due to processing in the cytoplasm of E. coli. The methionine-cleaved polypeptides, and hereby in particular the methionine-cleaved polypeptide of SEQ ID NO:l and SEQ ID NO:3, as well as the uncleaved forms of the AP205 polypeptides leading to AP205 VLPs in accordance with the present invention, or mixtures thereof also leading to AP205 VLPs in accordance with the present invention are embodiments and within the scope of the invention. AP205 Virus Like Particles In one embodiment, the invention provides AP205 coat proteins that form capsids. Such proteins are recombinantly expressed, or prepared from natural sources. Recombinant AP205 coat protein fragments able to assemble into a VLP are further embodiments of the invention. These fragments may be generated by deletion, either internally or at the termini of the coat protein. Insertions in the coat protein sequence or fusions to the coat protein sequence compatible with assembly into a VLP are further embodiments of the invention. The outcome of insertions, deletions and fusions to the coat protein sequence and whether it is compatible with assembly into a VLP can be determined by electron microscopy. The present invention provides methods of purification for the recombinant AP205 coat protein. The particles formed by the AP205 coat protein can be isolated in pure form by a combination of fractionation steps by precipitation and of purification steps by gel filtration. Other methods of isolating virus-like particles are known in the art, and may be used to isolate the virus-like particles (VLPs) of bacteriophage AP205. For example, the use of ultracentrifugation to isolate VLPs of the yeast retrotransposon Ty is described in U.S. Patent No. 4,918,166, which is incorporated by reference herein in its entirety. In addition to gel filtration, other chromatographic steps such as ion exchange, hydrophobic interaction or affinity chromatography may also be used. Expression of the recombinant AP205 coat protein leads to assembly into viruslike particles which, when analyzed by electron microscopy, have identical appearance and size as phage particles. It is a finding of the present invention, that the VLPs can be purified. This invention therefore provides a new VLP, which can be obtained in high amounts in a pure form. AP205 VLPs self-assembled in E. coli have identical appearance and size as AP205 phage particles. As has been shown for other VLPs (Polyoma VP1 VLPs and PapillomaLl VLPs, ChackerianB. et al.,PNAS 96:2373-2378 (1999)), manipulation of experimental conditions or fusion of epitopes to the VLP may lead to VLPs with a different state of assembly. For example, particles of lower triangulation number than the wt or major particle form may be obtained. Therefore, AP205 VLPs of smaller size than AP205 phage particles, or mixtures of AP205 VLPs of same size and smaller size than AP205 phage particles are also embodiments of the invention. When analyzed in non-reducing PAGE, the AP205 VLP subunits runs at a higher apparent molecular weight than when analyzed by reducing PAGE, showing that the subunits are associated by disulfide bridges as described in Example 17 of In a further aspect, the present invention provides a vector containing an open reading frame suitable for the production of an AP205 virus like particle, said vector further comprising an additional nucleic acid such that the resulting vector is capable of producing a recombinant AP205 virus-like particle comprising amino acids encoded by said additional nucleic acid. In another aspect, the present invention provides a vector containing an open reading frame suitable for the production of an AP205 virus like particle, said vector further comprising a restriction enzyme site suitable for the introduction of additional nucleic acid such that the resulting vector is capable of producing a recombinant viruslike particle comprising amino acids encoded by said additional nucleic acid. Organic Molecules, Haptens and Antigens Organic molecules used in the methods, conjugates and compositions of the present invention include any antigen, hapten, organic molecule, or fragment thereof.

Such treatment will be useful to treat a wide variety of infectious diseases affecting a wide range of hosts, e.g., human, cow, sheep, pig, dog, cat, other mammalian species and non-mammalian species as well. Such vaccines may be used prophylactically, to prevent an infection in an individual or population, or therapeutically, to mitigate an ongoing infection. Infectious diseases for which a vaccine is known or desired are well known to those skilled in the art, examples include infections of viral etiology such as HIV, influenza, Herpes, viral hepatitis, Epstein Barr, polio, viral encephalitis, measles, chicken pox, etc.; infections of bacterial etiology such as pneumonia, tuberculosis, syphilis, lyme disease, cholera, salmonellosis, meningitis, sepsis etc.; or infections of parasitic etiology such as malaria, trypanosomiasis, leishmaniasis, trichomoniasis, amoebiasis, etc. The antigens or antigenic determinants used in the conjugates, compositions and methods of the invention are known to those of ordinary skill in the relevant arts. Examples of antigens or antigenic determinants include the following: the HIV antigens gpl40 and gp160; the influenza antigens hemagglutinin, M2 protein and neuraminidase, Hepatitis B surface antigen, and circumsporozoite protein of malaria.

These haptens include, but are not limited to, hormones, drugs and toxic compounds. Immune responses against a variety of drugs, hormones and toxic compounds are used to protect an individual at risk of exposure to such compounds, as therapy in an individual exposed to such compounds, or to prevent or treat addictions to such compounds. Representative toxic compounds include, but are not limited to, the natural products of toxic plants, animals, and microorganisms. Such products include aflatoxin, ciguautera toxin, and tetrodotoxin. Other representative toxic compounds produced artificially, or as a result of metabolism include antibiotics (e.g. vancomycin), anticancer compounds (e.g. vinblastine) and chemical warfare agents (eg. Sarin, mustard gas, VX). One aspect of the invention includes the production of antibodies against toxic metabolites of commonly used pharmaceutical agents, such that an individual may continue to receive the beneficial effects of a pharmaceutical agent without side effects associated with toxic metabolites. Thus, in a preferred embodiment, the toxin is a metabolite generated in the body of an individual, wherein said metabolite is a metabolite of a pharmaceutical agent. In a further preferred embodiment, the toxin is a chemical warfare agent. Organic molecules, antigens or antigenic determinants suitable for use in conjugates, compositions and methods of treatment of drug addiction, in particular recreational drug addiction, will be known to those of ordinary skill in the relevant arts. Representative examples of organic molecules, antigens or antigenic determinants include, for example, opioids and morphine derivatives such as codeine, fentanyl, heroin, morphine and opium; stimulants such as amphetamine, cocaine, MDMA (methylenedioxymethamphetamine), methamphetamine, methylphenidate, and nicotine; hallucinogens such as LSD, mescaline and psilocybin; cannabinoids such as hashish and marijuana, other addictive drugs or compounds; and derivatives, byproducts, variants and complexes of such compounds. Allergies and Cancer In related embodiments, the invention provides compositions suitable for use as immunotherapeutics that may be used for the treatment or prevention of allergies or cancer. Antigens or antigenic determinants suitable for use in conjugates, compositions and methods of treatment or prevention of allergies would be known to those of ordinary skill in the relevant art Representative examples of such antigens or antigenic determinants include the following: bee venom phospholipase A2, Bet v I (birch pollen allergen), 5 Dol m V (white-faced hornet venom allergen), Mellitin and Der p I (House dust mite allergen), gluten, gliadin, shellfish allergens, cockroach allergens, peanut and other nut allergens, ragweed and other pollen allergens, grevillea allergen, as well as fragments of each which can be used to elicit immunological responses. In a particular embodiment of the invention, the allergen is selected from the group consisting of (a) a recombinant protein of bee sting allergy, (b) a recombinant proteins of nut allergy, (c) recombinant proteins of food allergies, (d) recombinant proteins of asthma, (e) a recombinant protein of Chlamydia, and (f) a fragment of any of the allergens of (a) through (e). As noted above, a suitable antigen or antigenic determinant for use in the conjugates, compositions or methods of the present invention is Der p L Der p I is a 25kD protease found in house dust mite faecal particles and represents the major allergen of house dust mite. Accordingly, 80% of mite allergic patients have anti-Der p I IgE antibodies. In particular, the Derplpeptidesp52-72andpll7-133 (SEQ ID NO: 64), among others, are known to comprise epitopes which are recognized by antibodies specific for the native Der p I. IgE antibodies raised in a polyclonal response to the whole antigen bind with high affinity to the peptide region 59-94 (L. Pierson-Mullany et al. (2000) Molecular Immunology). Other regions also bind IgE with high affinity. The peptide pi 17-133 contains a cysteine at its N-terminus representing the second attachment site in accordance with the invention. 3D modelling assigns peptides p52-72 and p117-133 to the surface of the whole protein (Jeannin, P. et al., Molecular Immunology 30:1511-1518 (1993)).However, other fragments of the Der p I protein may comprise B cell epitopes suitable for the present invention. In a preferred embodiment of the inventive composition, the antigen or antigenic determinant is a Der p I peptide, and wherein said Der p I peptide with said second attachment site has an amino acid sequence selected from the group consisting of: a) CGNQSLDLAEQELVDCASQHGCH (SEQ ID NO: 97); and b) CQIYPPNANKIREALAQTHSA (SEQ ID NO: 64). In additional embodiments, the invention provides vaccine compositions suitable for use in methods for preventing and/or attenuating allergic reactions, such as allergic reactions which lead to anaphylaxis. As disclosed elsewhere herein, allergic reactions may be characterized by the TH2 responses against an antigen leading to the presence of IgE antibodies. Stimulation of TH1 immune responses and the production of IgG antibodies may alleviate allergic disease. Thus, vaccine compositions of the invention include compositions which lead to the production of antibodies that prevent and/or attenuate allergic reactions. Thus, in certain embodiments, vaccine compositions of the invention include compositions which elicit an immunological response against an allergen. Examples of such allergens include phospholipases such as the phospholipase A2 (PLA2) proteins of Apis mellifera (GenBank Accession No. 443189, GenBank Accession No. 229378), Apis dorsata (GenBank Accession No. B59055), Apis cerarta (GenBank Accession No. A59055), Bombus permsylvanicus (GenBank Accession No. B56338), and Heloderma suspectum (GenBank Accession No. P80003; GenBank Accession No. S14764; GenBank Accession No. 226711). Using the amino acid sequence of a PLA2 protein of Apis mellifera (GenBank Accession No. 443189, GenBank Accession No. 229378) for illustration, peptides of at least about 60 amino acids in length, which represent any portion of the whole PLA2 sequence, may also be used in compositions for preventing and/or attenuating allergic reactions. Examples of such peptides include peptides which comprise amino acids 1-60, amino acids 1-70, amino acids 10-70, amino acids 20-80, amino acids 30-90, amino acids 40-100, amino acids 47-99, amino acids 50-110, amino acids 60-120, amino acids 70-130, or amino acids 90-134, as well as corresponding portions of other PLA2 proteins (e.g., PLA2 proteins described above). Further examples of such peptides include peptides which comprise amino acids 1-10, amino acids 5-15, amino acids 10-20, amino acids 20-30, amino acids 30-40, amino acids 40-50, amino acids 50-60, amino acids 60-70, amino acids 70-80, amino acids 80-90, amino acids 90-100, amino acids 100-110, amino acids 110-120, or amino acids 120-130, as well corresponding portions of other PLA2 proteins (e.g., PLA2 proteins described above). Portions of PLA2, as well as portions of other proteins against which an immunological response is sought, suitable for use with the invention may comprise, or alternatively consist of, peptides which are generally at least 6 amino acids in length (e.g., peptides 6,7, 8, 9,10,12,15,18,20,25,30,35,40,45,50, 55, 60,65,70,75, 80,85,90,95, or 100 amino acids in length). PLA2 peptides (e.g., the full length PLA2 proteins discussed above, as well as subportions of each) may also be coupled to any substance (e.g., an AP205 capsid protein or fragment thereof) which allows for the formation of ordered and repetitive antigen arrays. The selection of antigens or antigenic determinants for compositions and methods of treatment for cancer would be known to those of ordinary skill in the relevant arts. In a particular embodiment of the invention, the antigen or antigenic determinant is selected from the group consisting of: (a) a recombinant protein of breast cancer cells; (b) a recombinant protein of kidney cancer cells; (c) a recombinant protein of prostate cancer cells; (d) a recombinant protein of skin cancer cells; (e) a recombinant protein ofbrain cancer cells; (f) a recombinant protein of leukemia cells; (g) a recombinant profiling; and (h) a fragment of any of the proteins set out in (a)-(g)- Representative examples of such types of antigens or antigenic determinants include the following: Her2 (breast cancer), GD2 (neuroblastoma), EGF-R (malignant glioblastoma), CEA (medullary thyroid cancer), and CD52 (leukemia), human melanoma protein gp100, human melanoma protein melan-A/MART-1, tyrosinase, NA17-A nt protein, MAGE-3 protein, p53 protein, and HPV16 E7 protein, as well as fragments of each which can be used to elicit immunological responses. Further antigenic determinants useful for compositions and methods of treatment for cancer are molecules and antigenic determinants involved in angiogenesis. Angiogenesis, the formation of new blood vessels, plays an essential role in physiological and pathophysiological processes such as wound healing and solid tumor growth, respectively (Folkman, J. (1995) Nat. Medicine l,27-31;Folkman, J., and Klagsburn, M. (1987) Science 235, 442-446; Martiny-Baron, G., and Marme, D. (1995) Curr. Opin. Biotechnol. 6, 675-680; Risau, W. (1997) Nature 386, 671-674). Rapidly growing tumors initiate and depend on the formation of blood vessels to provide the required blood supply. Thus, it is believed that antiangiogenic agents are effective as anticancer therapeutics. Among several putative angiogenic factors that have been identified, vascular endothelial growth factor (VEGF) is a potent endothelial cell specific mitogen and a primary stimulant of the vascularization of many solid tumors. Thus, blockage of VEGF action is a target for intervention in tumor-induced angiogenesis, as a means of blocking the endothelium rather than the tumor as a strategy to fight tumors (Millauer, B. et al. (1994) Nature 367, 576-579; Kim, J et al (1993) Nature 362, 841-844). An anti-VEGFR-n antibody (TMC-1C11) and an anti-VEGF antibody have been disclosed (Lu, D. et al. (2000) J. Biol. Chem. 275,14321-14330; Presta, L.G, et al (1997) Cancer Res. 47, 4593-4599). The former neutralizing monoclonal anti-VEGFR-2 antibody recognizes an epitope that has been identified as putative VEGF/VEGFR-II binding site (Piossek, C.et al. (1999) J Biol Chem. 274,5612-5619). Thus, in one embodiment of the invention, the antigen or antigenic determinant used in conjugates, compositions or methods of the invention is a peptide derived from the VEGFR-II contact site. This provides a composition and a vaccine composition in accordance with the invention, which may have antiangiogenic properties useful for the treatment of cancer. Inhibition of tumor growth in mice using sera specific for VEGFR-2 has been demonstrated (Wei, YQ et al. (2000) Nature Medicine 6,1160-1165). Therefore, further antigenic determinants suitable for inventive compositions and antiangiogenic vaccine compositions in accordance with the invention comprise either the human VEGFR-II derived peptide with the amino acid sequence CTARTELNVGI DFNWEYPSSKHQHKK (SEQ ID NO: 99), and/or the murine VEGFR-II derived peptide having the amino acid sequence CTARTELNVGLDFTWHSPPSKSHHKK (SEQ ID NO: 113), and/or the relevant extracellular globular domains 1-3 of the VEGFR-II. Self-Antigens In specific embodiments, the invention provides vaccine compositions suitable for use in methods for preventing and/or attenuating diseases or conditions which are caused or exacerbated by "self gene products (e.g., tumor necrosis factors). It is usually difficult if not impossible to induce antibody responses to self-molecules by conventional vaccination." The present invention provides one way to improve the efficiency of vaccination by increasing the degree of repetitiveness of the antigen to be used for immunization, through binding of the antigen to the AP205 VLP. Unlike isolated proteins, viruses induce prompt and efficient immune responses in the absence of any adjuvants both with and without T-cell help (Bachmann & Zinkernagel, Ann. Rev. Immunol: 15:235-270 (1997)). Although viruses often consist of few proteins, they are able to trigger much stronger immune responses than their isolated components. For B-cell responses, it is known that one crucial factor for the immunogenicity of viruses is the repetitiveness and order of surface epitopes. Many viruses exhibit a quasi- crystalline surface that displays a regular array of epitopes which efficiently crosslinks epitope-specific immunogl obulins on B cells (Bachmann & Zinkernagel, Immunol. Today 17:553-558 (1996)). This crosslinking of surface immunoglobulins on B cells is a strong activation signal that directly induces cell-cycle progression and the production of IgM antibodies. Further, such triggered B cells are able to activate T helper cells, which in turn induce a switch from IgM to IgG antibody production in B cells and the generation of long-lived B cell memory - the goal of any vaccination (Bachmann & Zinkernagel, Ann. Rev. Immunol. 15:235-270 (1997)). Viral structure is even linked to the generation of anti-antibodies in autoimmune disease and as a part of the natural response to pathogens (see Fehr, T., et al, J Exp. Med. 755:1785-1792 (1997)). Thus, antibodies presented by a highly organized viral surface are able to induce strong anti-antibody responses. The immune system usually fails to produce antibodies against self-derived structures. For soluble antigens present at low concentrations, this is due to tolerance at the Th cell level. Under these conditions, coupling the self-antigen to a carrier that can deliver T help may break tolerance. For soluble proteins present at high concentrations or membrane-associated proteins at low concentration, B and TH cells may be tolerant However, B cell tolerance may be reversible (anergy) and can be broken by administration of the antigen in a highly organized fashion coupled to a foreign carrier (Bachmann & Zinkernagel, Ann. Rev. Immunol 15:235-270 (1997). Thus, vaccine compositions of the invention include conjugates, compositions and methods which lead to the production of antibodies that prevent and/or attenuate diseases or conditions caused or exacerbated by "self gene products. Examples of such diseases or conditions include graft versus host disease, IgE-mediated allergic reactions, anaphylaxis, adult respiratory distress syndrome, Crohn's disease, allergic asthma, acute lymphoblastic leukemia (ALL), diabetes, non-Hodgkin's lymphoma (NHL), Graves' disease, systemic lupus erythematosus (SLE), inflammatory autoimmune diseases, myasthenia gravis, immunoproliferative disease lymphadenopathy (GPL), angioimmunoproliferative lymphadenopathy (AIL), immunoblastive lymphadenopathy (IBL), rheumatoid arthritis, diabetes, multiple sclerosis, Alzheimer disease, osteoporosis, and autoimmune conditions associated with certain infections including rheumatic fever, scarlet fever, lyme disease, and infectious polyarthritis. The selection of antigens or antigenic determinants for conjugates, compositions and methods of treatment for other diseases or conditions associated with self antigens would be also known to those of ordinary skills in the relevant art. Representative examples of such antigens or antigenic determinants are, for example, lymphotoxins (e.g. Lymphotoxin a (LTα), Lymphotoxin ß (LT (3)), andlymphotoxin receptors, Receptor activator of nuclear factor kB ligand (RANKL), vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor (VEGF-R), Interleukin-5, Interleukin-17, Merleukin-13, CCL21, CXCL12, SDF-1, MCP-1, Endoglin, Resistin, GHRH, LHRH, TRH, MIF, Eotaxin, Bradykinin, BLC, Tumor Necrosis Factor a and amyloid beta peptide (Aß142), as well as fragments of each which can be used to elicit immunological responses. In one embodiment, the antigenic determinant is the amyloid beta peptide (Aß1-42)(DAEFFHDSGYEVHHQKLVFFAEDVGSNKGAnGLMVGGVVIA(SEQ ID NO: 7), or a fragment thereof. Aß peptide has a central role in the neuropathology of Alzheimers disease. Region specific, extracellular accumulation of Aß peptide is accompanied by microgliosis, cytoskelet al changes, dystrophic neuritis and synaptic loss. These pathological alterations are thought to be linked to the cognitive decline that defines the disease. In a mouse model of Alzheimer disease, transgenic animals engineered to produce Aß1-42 (PDAPP-mice), develop plaques and neuron damage in their brains. Recent work has shown immunization of young PDAPP-mice, using Aß1-42, resulted in inhibition of plaque formation and associated dystrophic neuritis (Schenk, D. et al., Nature 400:173-77 (1999)). Furthermore immunization of older PDAPP mice that had already developed AD-like neuropathologies, reduced the extent and progression of the neuropathologies. In another study, peripherally administered antibodies raised against Aß1-42, were able to induce clearance of pre-existing amyloid (Bard, F. et al.t Nature Medicine 5:916-19 (2000)). This study utilized either polyclonal antibodies raised against Aß1-42. or monoclonal antibodies raised against synthetic fragments derived from different regions of Ap. Thus induction of antibodies against Aß using the conjugates, compositions and methods of the present invention can be considered as a potential therapeutic treatment for Alzheimer disease. It is well established that the administration of purified proteins alone is usually not sufficient to elicit a strong immune response; isolated antigen generally must be given together with helper substances called adjuvants. Within these adjuvants, the administered antigen is protected against rapid degradation, and the adjuvant provides an extended release of a low level of antigen. In the present invention, Aß peptide or fragments thereof are made immunogenic through binding to AP205 VLP and do not necessarily require an adjuvant As indicated, one of the key events in Alzheimer's Disease (AD) is the deposition of amyloid as insoluble fibrous masses (amyloidogenesis) resulting in extracellular neuritic plaques and deposits around the walls of cerebral blood vessels (for review see Selkoe, D. J. (1999) Nature. 399, A23-31). The major constituent of the neuritic plaques and congophilic angiopathy is amyloid ß (Aß), although these deposits also contain other proteins such as glycosaminoglycans and apolipoproteins. Aß is proteolytically cleaved from a much larger glycoprotein known as Amyloid Precursor Proteins (APPs), which comprises isoforms of 695-770 amino acids with a single hydrophobic transmembrane region. Aß forms a group of peptides up to 43 amino acids in length showing considerable amino- and carboxy-terminal heterogeneity (truncation) as well as modifications (Roher, A. E. et al (1988) J. Cell Biol. 107,2703-2716. Roher, A. E. et al (1993) J. Neurochem. 61,1916-1926). Prominent isoforms are Afi 1-40 and 1-42. It has a high propensity to form fi-sheets aggregating into fibrils, which ultimately leads to the amyloid. Recent studies have demonstrated that a vaccination-induced reduction in brain amyloid deposits resulted in cognitive improvements (Schenk, D. et al. (1999) Nature. 400,173-177). Hence, fragments of Aß suitable for generating vaccines of the invention include, but are not limited to: Ap 1-15, Aß 1 -27 and Aß 33-42. An amino acid linker is fused to the aminoacid sequence of Afi or Afi fragments to allow coupling to the AP205 VLP, as described elsewhere herein. Amino acid linkers suitable for fusion to the N-terminus of Afi or Afi fragments include but are not limited to the sequence CGG and CGHGNKS. Linkers suitable for fusion to the C-terminus of Afi or Afi fragments include but are not limited to the sequence GGC. In one embodiment, when a linker is fused to the C-terminus of Afi or Afi fragments, the C-terminal cysteine is amidated. The Afi fragment 1-15 is fused to an amino acid linker and has the sequence: DAEFRHDSGYEVHHQGGC-NH2 (SEQ ID NO: 8), wherein the C.terminal cysteine is amidated, which is indicated by the C-terminal "NIK". The Afi fragment 1-27 is fused to an amino acid linker and has the sequence: DAEFRHDSGYEVHHQKLVFFAEDVGSNGGC-NH2 (SEQ ID NO: 9). The Afi fragment 33-42 is fused to an amino acid linker and has the sequence: CGHGNKSGLMVGGVVIA (SEQ ID NO: 10). In one embodiment of the invention, the antigen or antigenic determinant comprises, or preferably is, an angiotensin peptide or a fragment thereof. The term "angiotensin peptide" as used herein, encompasses any peptide comprising the sequence, or any fragment thereof, of angiotensinogen, angiotensin I or angiotensin H. Angiotensin is associated with hypertension (Gardiner et al, Br. J. Pharm. 129:1178 (2000)). Therefore, conjugates, compostion and methods of present invention suitable for reducing levels of angiotensin are suitable for the treatment of hypertension. In one embodiment, the conjugate or composition comprises at least one angiotensin peptide. The amino acid sequences sequences of peptides in some embodiments are as follows: Angiotensinogen: DRVYIHPFHLVIHN (SEQ ID NO: 11); Angiotensin I: DRVYIHPFHL (SEQ ID NO: 12); Angiotensin II: DRVYIHPF (SEQ ID NO: 13). Typically, one or more additional amino acids are added at the C- and/or at the N-terminus of the angiotensin peptide sequences. Those additional amino acids are, in particular, valuable for an oriented and ordered association to the Aß 205 virus-like particle. The sequence of the angiotensin peptides corresponds to the human sequence, which is identical to the murine sequence. Therefore, immunization of a human or a mouse with vaccines or compositions, respectively, comprising such angiotensin peptides as an antigen or antigenic determinant in accordance with the invention, is a vaccination against a self-antigen. In some embodiments, the angiotensin peptide with said second attachment site has an amino acid sequence selected from the group consisting of a) the amino acid sequence of CGGDRVYIHPF (SEQ ID NO: 14); b) the amino acid sequence of CGGDRVYIHPFHL (SEQ ID NO: 15); c) the amino acid sequence of DRVYIHPFHLGGC (SEQ ID NO: 16); and d) the amino acid sequence of CDRVYIHPFH (SEQ ID NO: 98). In another embodiment of the invention, the antigenic determinant is RANKL (Receptor Activator of NFkB Ligand). RANKL is also known as TRANCE (TNF-related Activation Induced Cytokine), ODF (Osteoclast Differentiation Factor) or OPGL (Osteoprotegerin Ligand). The amino acid sequence of the extracellular part of human RANKL is shown in EMBL database deposit RANKLJiuman: TrEMBL:014788. Sequences for the extracellular part of murine RANKL and an isoform are shown in EMBL database deposits RANKL_mouse: TrEMBL:035235, and in RANKL_mouse splice forms: TrEMBL:Q9JJK8 and TrEMBL:Q9JJK9, respectively. It has been shown that RANKL is an essential factor in osteoclastogenesis. Inhibition of the interaction of RANKL with its receptor RANK can lead to a suppression of osteoclastogenesis and thus provide a means to stop excessive bone resorption as seen in osteoporosis and other conditions. The RANKL/RANK interaction was inhibited either by a RANK-Fc fusion protein or the soluble decoy receptor of RANKL, termed osteoprotegerin (OPG.) In bone, RANKL is expressed on stromal cells or osteoblasts, while RANK is expressed on the osteoclast precursor. The interaction of RANK and RANKL is crucial for the development of osteoclast precursors to mature osteoclasts. The interaction can be blocked by OPG. OPG-deficient mice develop osteoporosis that can be rescued by injection of recombinant OPG, suggesting that OPG is able to reverse osteoporosis. Thus, inhibition of the RANK-RANKL interaction by providing suitable conjugates, of human RANKL, comprise one embodiment of the invention, and are modified for coupling to AP205 VLP as required according to the teachings of the present invention. The invention also embodies other suitable vectors used for expression in the suitable host described below. Additional human-RANKL constructs that are intended to be encompassed within the scope of the present invention include those comprising the part of the extracellular region (178 aa) or fragments thereof that can be shed by a TACE-like protease (Lum et al, JBiolChem. 274:13613 (1999)), or that comprise the sequence corresponding to the alternative splice variants lacking the transmembrane domain, as well as conservative fragments thereof. Human C-terminal fragments of RANKL comprising amino acids 165-317 are also embodiments of the invention. Fragments of RANKL which encompass the entire extracellular region (amino acids 71-317) and can be modified for coupling to AP205 VLP and as required according to the teaching of the present invention, are also within the scope of the invention. RANKL has been expressed in different systems (e.g E.coli, insect cells, mammalian cells) and has been shown to be active. Therefore, several expression systems can be used for production of suitable RANKL antigens of the composition. In the case where expression of the protein is directed to the periplasm of E. coli, the signal peptide of RANKL, or of RANKL constructs consisting of the extracellular part of the protein, and both possibly modified to comprise a second attachment site in accordance with the invention, is replaced with a bacterial signal peptide. For expression of the protein in the cytoplasm of E. coli, RANKL constructs are devoid of signal peptide. In one embodiment of the invention, the antigenic determinant is MF or a fragment thereof. MIF is a cytokine that functions as an inhibitor of macrophage migration. It is also known as delayed early response protein 6 (DER6), glycosyiation inhibiting factor or phenylpyruvate tautomerase. MIF has been shown to be implicated in a wide range of conditions. MIF (mRNA and protein) is upregulated in delayed type hypersensitivity (DTH) reaction induced by tuberculin, and anti-MIF antibody inhibits this DTH reaction. MIF is also upregulated in renal allograft rejection. In a model for ocular autoimmune disease, experimental autoimmune uveoretinitis (EAU), anti-MIF treatment caused delay of EAU development. In patients, there is an increase in serum of MIF, which is also the case in Behcet's disease patients and patients suffering from iridocyclitis. Immunization against MIF may provide a way of treatment against rheumatoid arthritis. Thus conjugates, composites and methods of the invention suitable for immunizing againts MIF, or for reducing serum MIF, are useful in the treatment or prevention of those diseases, disorders and conditons associated with overproduction ofMIF. High serum MIF concentration has been found in atopic dermatitis patients. In skin lesions, MIF is diffusely expressed instead of being found in the basal cell layer in controls.MIF concentration is decreased after steroid treatment, consistent with a role of MIF in inflammation. MIF has also been found to contribute to the establishment of glomerulonephritis. Animals treated with anti-MIF antibody show significantly reduced glomerulonephritis. MIF is pituitary derived, secreted e.g. upon LPS stimulation, and potentiates endotoxemia. Accordingly, anti-MIF mAb inhibits endotoxemia and septic shock, while recombinant MIF markedly increases lethality of peritonitis. MIF is also a glucocorticoid-induced modulator of cytokine production, and promotes inflammation. MIF is also produced by T-cells (TH2), supports proliferation of T-cells, and anti-MIF-treatment reduces T-cell proliferation and IgG levels. There is an increased MIF concentration in the cerebrospinal fluid of multiple sclerosis and neuro-Behcet's disease patients. High MIF levels were also found in sera of patients with extended psoriasis. High MIF levels are found in sera of ulcerative colitis patients but not Crohn's disease patients. High MIF levels have been found in sera of patients with bronchic asthma. MIF is also upregulated in synovial fluid of rheumatoid arthritis patients. Anti-MIF treatment was effectivly decreasing rheumatoid arthritis in mouse and rat models (Mikulowska et al, J. Immunol. 755:5514-7(1997); Leech et al, Arthritis Rheum. 41:910-7 (1998), Leech et al Arthritis Rheum. 43:827-33 (2000), Santos et al, Clin. Exp. Immunol i23:309-14 (2001)). Thus, treatment directed at inhibiting MIF activity using a composition comprising MIF as an antigenic determinant are beneficial for the conditions mentioned above. MIF from mouse, rat and human consists of 114 amino acid and contains three conserved cysteines, as shown in MIF_rat: SEQ ID NO: 120, MIF_mouse: SEQ ID NO: 121 and in MIFJiuman: SEQ ID NO: 119 SwissProt. Three subunits form a homotrimer that is not stabilized by disulfide bonds. The X-ray structure has been solved and shows three free cysteines (Sun et al, PNAS 93: 5191-96 (1996)), while some literature data claim the presence of a disulfide bond. Nonetheless, none of the cysteines are exposed enough for optimal interaction with a possible first attachment site present on the carrier. Thus, as the C-terminus of the protein is exposed in the trimer structure, an amino acid linker containing a cysteine residue is, in one aspect, added to the C-terminus of the protein, for generation of the second attachment site in this embodiment of the invention. There is only one amino acid change between mouse- and rat-MIF, and similarly a very high sequence homology (about 90 % sequence identity) between human- and rat-MIF or human- and mouse-MIF. The invention embodies conjugates, compositions and methods comprising human- and mouse-MIF constructs associated to the AP205 VLP. An amino acid linker containing a cysteine that is added at the N-terminus of the sequence of MIF leads to further embodiments of the present invention. MIF has been expressed in E.coli, purified and shown to be fully functional (Bernhagen et al, Biochemistry 33: 14144-14155 (1994). Thus, MIF may be expressed in E. coli for generating the useful embodiments of the invention. Tautomerase activity of MIF is inhibited if the start methionine is not cleaved from the construct. MIF constructs expressed in E.coli show tautomerase activity. Mutants of MIF where the start methionine is cleaved and where the proline residue right after the start methionine in the sequence is mutated to alanine also do not show tautomerase activity and represent further embodiments of the invention and are intended to be encompassed within the scope of the invention. In one specific embodiment, AP205 is conjugated to MIF mutants devoid of tautomerase activity. In one embodiment of the invention, the antigen or antigenic determinant is Interleukin-17 (EL-17). Human BL-17 is a 32-kDa, disulfide-linked, homodimeric protein with variable glycosylation (Yao, Z. et al, J. Immunol 155:5483-5486 (1995); Fossiez, F. et al, J. Exp. Med. 183: 2593-2603 (1996)). The protein comprises 155 amino acids and includes an N-terminal secretion signal sequence of 19-23 residues. The amino acid sequence of IL-17 is similar only to a Herpesvirus protein (HSV13) and is not similar to other cytokines or known proteins. The amino acid sequence of human IL-17 is shown in GenBank ACCESSION #: AAC50341. The mouse protein sequence is shown in GenBank ACCESSION #: AAA37490. Of the large number of tissues and cell lines evaluated, the mRNA transcript encoding IL-17 has been detected only in activated T cells and phorbol 12-myristate 13-acetate/ionomycin-stimulated peripheral blood mononuclear cells (Yao, Z. et al, J. Immunol 155:5483-5486 (1995); Fossiez, F. et al, J. Exp. Med. 183: 2593-2603 (1996)). Both human and mouse sequences contain 6 cysteine residues. The receptor for IL-17 is widely expressed in many tissues and cell types (Yao, Z. et al, Cytokine 9:794-800 (1997)). Although the amino acid sequence of the human IL-17 receptor (866 aa) predicts a protein with a single trans-membrane domain and a long, 525 aa intracellular domain, the receptor sequence is unique and is not similar to that of any of the receptors from the cytokine/growth factor receptor family. This coupled with the lack of similarity of IL-17 itselfto other known proteins indicates that IL-17 and its receptormay be part of anovel family of signalling protein andreceptors. Clinical studies indicate IL-17 may be involved in many inflammatory diseases. IL-17 is secreted by synovial T cells from rheumatoid arthritis patients and stimulates the production of inflammatory mediators (Chabaud,M. et al., J. Immunol. 161:409414 (1998); Chabaud, M. et al, Arthritis Rheum. 42:963-970 (1999)). Highlevels of IL-17 have been reported in patients with rheumatoid arthritis (Ziolkowska M. et al, J Immunol 164:2832-8 (2000)). Interleukin-17 has been shown to have an effect on proteoglycan degradation in murine knee joints (Dudler J. et al, Ann Rheum Dis. 59:529-32 (2000)) and contribute to destruction of the synovium matrix (Chabaud M. et al, Cytokine. 72:1092-9 (2000)). There are relevant arthritis models in animals for testing the effect of immunization against IL-17 (Chabaud M. et al, Cytokine. 72:1092-9 (2000)). Elevated levels of IL-17 mRNA have been found in mononuclear cells from patients with multiple sclerosis (Matusevicius,D. et al, Mult. Scler. 5:101-104 (1999)). Elevated serum levels of IL-17 are observed in patients suffering Systemic Lupus Erythematosus (Wong C.K. et al, Lupus 9: 589-93 (2000)). In addition, IL-17 mRNA levels are increased- in T cells isolated from lesional psoriatic skin (Teunissen, M. B. et al, J. Invest. Dermatol. Ill: 645-649(1998)). The involvement of IL-17 in rejection of kidney graft has also been demonstrated (Fossiez F. et al, Int. Rev. Immunol. 16:541-51 (1998)). Evidence for a role of IL-17 in organ allograft rejection has also been presented by Antonysamy et al (J. Immunol. 7(52:577-84 (1999)) who showed IL-17 promotes the functional differentiation of dendritic cell progenitors. Their findings suggest a role for IL-17 in allogeneic T cell proliferation that may be mediated in part via a maturation-inducing effect on DCs. Furthermore the same group reports (Tang J.L. et al, Transplantation 72:348-50 (2001)) a role for IL-17 in the immunopathogenesis of acute vascular rejection .where Interleukin-17 antagonism inhibits acute but not chronic vascular rejection. EL-17 appears to have potential as a novel target for therapeutic intervention in allograft rejection. The anti-IL-17 monoclonal antibody mAb5 (Schering-Plough Research Institute) is able to completely inhibit the production of IL-6 from rheumatoid arthritis (RA) synovium supernatants following induction by 50 ng/ml of IL-17. An irrelevant mAb MX1 had no effect in this assay. mAb5 is a mouse IgGl obtained after immunization with human rIL-17 (r = recombinant). A concentration of 1 µg/ml of mAb5 was able to completely inhibit the IL-6 production in the assay system (Chabaud, M. et al., J. Immunol 161:409-414 (1998)). Thus, immunization against IL-17 provides a way of treatment for the various conditions described above. Thus, in one embodiment of the invention the composition comprises a linker containing a second attachment site fused to the C-terminus of recombinant IL-17. In further embodiments an amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. For eukaryotic expression systems, the signal peptide of the IL-17 gene, as it is the case for the other self-antigens indicated herein, may be replaced by another signal peptide, for example originating from a specific eukaryotic expression vector. For expression in bacteria, the signal peptide is replaced by a bacterial signal peptide for soluble expression in the periplasm. For expression in the cytoplasm, the construct is devoid of signal peptide. Constructs of human IL-17 devoid of signal peptide will, in some embodiments, comprise residues 24-155,22-155,21-155 or 20-155. Constructs of mouse IL-17 devoid of signal peptide will, in some embodiments, comprise residues 26-158,25-158,24-158 or 27-155. Human IL-17 may be expressed in CV1/EBNA cells; recombinant hIL-17 has been shown to be secreted in both glycosylated and nonglycosylatedforms (Yao, Z. era/., J. Immunol 155:5483-5486 (1995)). IL-17 can also be expressed as hIL-17/Fc fusion protein, with subsequent cleavage of the IL-17 protein from the fusion protein. IL-17 may also be expressed in the yeast Pichiapastoris (Murphy K.P. et. al., Protein Expr Purif. 12:208-14 (1998)). Human IL-17 may also be expressed in E. coll When expression of IL-17 in E. coli is directed to the periplasm, the signal peptide of IL-17 is replaced by a bacterial signal peptide. In one embodiment , IL-17 constructs are devoid of signal peptide for expression of the protein in the cytoplasm of E, coli, In another embodiment of the invention the antigenic determinant is Interleukin-13 (IL-13). IL-13 is a cytokine that is secreted by activated T lymphocytes and primarily impacts monocytes, macrophages, and B cells. The first 20 amino acids of the precursor protein correspond to the signal peptide, and are absent of the processed protein. The mouse sequence has also been described (Brown K.D. et al, J. Immunol. 142:679-687 (1989)). Depending on the expression host, the IL-13 construct will comprise the sequence of the precursor protein, e.g. for expression and secretion in eukaryotic hosts, or consist of the mature protein, e.g. for cytoplasmic expression in E.coli. For expression in the periplasm of E. coli, the signal peptide of IL-13 is replaced by a bacterial signal peptide. IL-13 is a T helper 2-derived cytokine (like IL-4, IL-5) that has recently been implicated in allergic airway responses (asthma). Upregulation of IL-13 and IL-13 receptor has been found in many tumour types (e.g. Hodgkin lymphoma). Interleukin 13 is secreted by and stimulates the growth of Hodgkin and Reed-Sternberg cells (Kapp U. et al, J Exp Med. 189:1939-46 (1999)). Thus, immunization against IL-13 provides a way of treating among others the conditions described above, such as Asthma or Hodgkins Lymphoma. In one embodiment, the composition comprises an amino acid linker containing a cysteine residue and being fused to the N or C-terminus of the sequence of mature IL-13 to introduce a second attachment site within the protein. In other embodiments, an amino acid linker containing a cysteine is added to the N-terminus of the mature form of IL-13, since it is freely accessible according to the NMR structure of IL-13 (Eisenmesser, E. Z. et al., JMol Biol. 310', 231 (2001)). In other embodiments, the amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. In other embodiments, an amino acid linker containing a cysteine residue is added to the C-terminus of the protein. EL-13 may be expressed in E.coli (Eisenmesser E.Z. et al., Protein Expr. Purif. 20:186-95 (2000)), or in NS-0 cells (eukaryotic cell line) (Cannon-Carlson S. et al, Protein Expr. Purif.72:239-48 (1998)). In one embodiment of the invention, the antigenic determinant is Interleukin-5 (IL-5). IL-5 is a lineage-specific cytokine for eosinophiiopoiesis and plays an important part in diseases associated with increased number of eosinophils, such as asthma. The biological function of IL-5 has been shown in several studies (Coffman R.L. et al, Science 245:308-10 (1989); Kopf et al, Immunity 4:15-24 (1996)), which point to a beneficial effect of inhibiting IL-5 function in diseases mediated through eosinophils. Inhibition of the action of IL-5 provides thus a way of treatment against asthma and other diseases associated with eosinophils. IL-5 forms a dimer, covalently linked by a disulfide bridge. A single chain (sc) construct has been reported wherein two monomers of IL-5 are linked by a peptide linker. In one embodiment of the invention, a peptide linker containing a cysteine is added at the N-terminus of the sequence of the processed form of IL-5. Addition of a linker containing a cysteine is also envisaged at the N-terminus of the sequence of the processed form of a scIL-5. In other embodiments, the amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. In other embodiments, a linker containing a cysteine is fused to the C- terminus of the sequence of IL-5, or to the C-terminus of a scIL-5 sequence. A number of expression systems have been described for IL-5 and can be used in preparing the compositions of the invention. A bacterial expression system using E.coli has been described by Proudfoot et al, (Biochem J. 270:357-61 (1990)). In the case where IL-5 is expressed in the cytoplasm of E. coli, the IL-5 construct is devoid of a signal peptide. Insect cells may also be used for producing IL-5 constructs for making the compositions of the invention (Pierrot C. et al, Biochem. Biophys. Res. Commun. 253:756-60 (1998)). Likewise, Baculovirus expression systems (sf9 cells; Ingley E. et al, Eur. J. Biochem. 196:623-9 (1991) and Brown P.M. et al, Protein Expr. Purif. 6: 63-71 (1995)) can also be used. Finally, mammalian expression systems have also been reported (CHO cells) and can be used in preparing these compositions of the invention (Kodama S et al., J. Biochem. (Tokyo) 110:693-701 (1991)). Baculovirus expression systems (Mitchell et al, Biochem. Soc. Trans. 2/:332S (1993); Kunimoto DY et al, Cytokine 5:224-30 (1991)) and a mammalian cell expression system using CHO cells (Kodama S et al, Glycobiology 2:419-27 (1992)) have also been described for mouse IL-5. The expression of murine IL-5 constructs wherein the IL-5 sequence is fused at its N-terminus to amino acid linkers containing a cysteine residue are suitable for coupling of IL-5 to AP205 VLP. Human constructs can be generated according to the teachings herein yield the proteins human C-IL-5-E, human C-IL-5-F and human C-IL-5-S suitable for coupling to AP205 VLP and leading to other embodiments of the invention. In one embodiment of the invention, the antigenic determinant is CCL-21. CCL-21 is a chemokine of the CC subfamily that is also known as small inducable cytokine A21, as exodus-2, as SLD (secondary lymphocyte cytokine), as TCA4 (thymus-derived chemotactic agent 4) or 6Ckine. CCL21 inhibitis hemopoiesis and stimulates chemotaxis for thymocytes, activated T-cells and dendritic cells, but not for B cells, macrophages or neutrophils. It shows preferential activitiy towards naive T cells. It is also a potent mesangial cell chemoattractant CCL21 binds to chemokine receptors CCR7 and to CXCR3 (depending on the species). It can trigger rapid integrin-dependent arrest of lymphocytes rolling under physiological shear and is highly expressed by high endothelial venules. Murine CCL21 inhibited tumor growth and angiogenesis in a human lung cancer SCID mouse model (Arenberg et al, Cancer Immunol Immunother. 49:587-92 (2001)) and a colon carcinoma tumor model in mice (Vicari et ah, J. Immunol 165: 1992-2000 (2001)). The angiostatic activity of murine CCL21 was also detected in a rat corneal micropocket assay (Soto et ah, Proc. Nath Acad. Sci. USA 95: 8205-10 (1998). It has been shown that chemokine receptors CCR7 and CXCR.4 are upregulated in breast cancer cells and that CCL21 and CXCL12, the respective ligands, are highly expressed in organs representing the first destinations of breast cancer metastasis (Mtiller et al. (Nature 410:50-6 (2001)). In vitro CCL21 -mediated chemotaxis could be blocked by neutralizing anti-CCL21 antibodies as was CXCR4-mediated chemotaxis by the respective antibodies. Thus, immunization against CCL21 provides a way of treatment against metastatis spread in cancers, more specifically in breast cancer. Secreted CCL21 consist of 110 or 111 aa in mice and humans, respectively. The respective sequences are shown in Swissprot: SY21_human and in Swissprot: SY21_mouse. In contrast to other CC cytokines does CCL21 contain two more cysteines within an extended region at the C-terminus. It is assumed that all cysteines are engaged in disulfide bonds. In the following, constructs and expression systems are described for making compositions of the invention comprising the CCL21 antigenic determinant In the NMR structure of the homologous protein eotaxin, both N- and C-terminus are exposed to the solvent. In some embodiments, an amino acid linker containing a cysteine residue as a second attachment site is added at the C-terminus of the protein. A fusion protein with alkaline phosphatase (at the C-terminus of CCL21) has been expressed and was shown to be functional, showing that fusions at the C-terminus of CCL21 are compatible with receptor binding. In specific embodiments, the amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. Several expression systems have been described for production of CCL21 (e.g. Hedrick et al, J Immunol 159: 1589-93 (1997)). For example, it may expressed in a baculovirus system (Nagira et al.s J. Biol. Chem. 272:19518-24 (1997)). In a related embodiment, the antigenic determinant is Stromal derived factor-1 (SDF-1); now termed CXCL12. CXCL12 is a chemokine produced by bone marrow stromal cells and was originally identified as a stimulatory factor for pre-B cells. As stated above, it has been shown that chemokine receptors CCR7 and CXCR4 are upregulated in breast cancer cells and that CCL21 and SDF-1, the respective ligands, are highly expressed in organs representing the first destinations of breast cancer metastasis (Muller et al. Nature 410: 50-6 (2001)). In vitro SDF-1 / CXCR4-mediated chemotaxis could be inhibitied by neutralizing anti-SDF-1 and anti-CXCR4 antibodies. In a breast cancer metastasis model in SCID mice using the human MDA-MB-231 breast cancer cell line, a significant decrease in lung metastasis was observed when mice were treated with anti-CXCR4 antibodies, In the draining lymph nodes, a reduction of metastasis to the inguinal and axillary lymph nodes (38% instead of 100% metastasis in controls) was observed. Thus, immunization against CXCL12 provides a way of treatment against metastatis of cancers, more specifically of breast cancers. The SDF-1 / CXCR4 chemokine-receptor pair has been shown to increase the efficacy of homing of more primitive hematopoietic progenitor cells to be bone marrow. In addition, CXCR4 and SDF-1 are supposed to influence the distribution of chronic lymphocytic leukemia cells. These cells invariably infiltrate the bone marrow of patients and it was shown that their migration in the bone marrow was CXCR4 dependent. Chronic lymphocytic leukemia cells undergo apoptosis unless they are cocultured with stromal cells. SDF-1 blocking antibodies could inhibit this protective effect of stromal cells (Burger et al, Blood 96:2655-63 (2000)). Immunizing against CXCL12 thus provides a way of treatment against chronic lymphocytic leukemia. CXCR4 has been shown to be a coreceptor for entry of HIV into T-cells. SDF-1 inhibits infection of CD4+ cells by X4 (CXCR4-dependent) HTV strains (Oberlinet al., Nature 352:833-5 (1996); Bleul et al, Nature 352:829-33 (1996), Rusconi et al, Antivir. Ther. 5:199-204 (2000)). Synthetic peptide analogs of SDF-1 have been shown to effectively inhibit HIV-1 entry and infection via the CXCR4 receptor(WO05992SAl). Thus, immunization against CXCL12 provides a way to block HIV entry in T-cells, and therefore a way of treating AIDS. SDF-1 -CXCR.4 interactions were also reported to play a central role in CD4+ T cell accumulation in rheumatoid arthritis synovium (Nanki et al., 2000). Immunization against SDF-1 thus provides a way of treatment against rheumatoid arthritis. Human and murine SDF-1 are known to arise in two forms, SDF-1α and SDF-1ß, by differential splicing from a single gene. They differ in four C-terminal amino acids that are present in SDF-10 (74 aa) and absent in SDF-1α (70 aa). The sequence of human SDF-1 is shown in Swissprot: SDFl_human and the sequence of mouse SDF-1 is shown inSwissprot: SDF1_mouse. SDF-1 contains four conserved cysteines that form two intra-molecular disulfide bonds. The crystal structure of SDF shows a non covalently-linked dimer (Dealwis et al, PNAS 95:6941-46 (1998)). The SDF-1 structure also shows a long N-terminal extension. Alanke-scanning mutagenesis was used to identify (part of) the receptor-binding site on SDF-1 (Ohnishi et al, J. Interferon Cytokine Res. 20:691-700 (2000)) and Elisseeva et al. (J. Biol Chem. 275:26799-805 (2000)) and Heveker et al. (Curr. Biol. 5:369-76 (1998)) described SDF-1 derived peptides inhibiting receptor binding (and HIV entry). In the following, constructs and expression systems suitable for the generation of the compositions of the invention related to SDF-1 are described. The N- and C-tenninus of SDF-1 are exposed to the solvent In specific embodiments, an amino acid linker containing a cysteine as second attachment site is thus fused to the C- terminus of the protein sequence, while in other specific embodiments an amino acid linker containing a cysteine as second attachment site is fused to the N-terminus of the protein sequence. The amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. The genes coding for these specific constructs may be cloned in a suitable expression vector. Expression of SDF-1 in a sendai virus system in chicken embryonic fibroblasts (Moriya et al., FEBS Lett. 425:105-11 (1998)) has been described as well as expression in E.coli (Holmes et al, Prot. Expr. Purif. 21:367-77 (2001)) and chemical synthesis of SDF-1 (Dealwis et al, PNAS 95:6941-46 (2001)). In another embodiment of the invention, the antigenic determinant is B-lymphocyte chemoattractant (BLC, CXCL13). BLC is expressed in the spleen, Peyer's patches and lymph nodes (Gunn et al., 1998). Its expression is strongest inthe germinal centres, where B cells undergo somatic mutation and affinity maturation. It belongs to the CXC chemokine family, and its closest homolog is GROa (Gunn et al, Nature 391 -.799-803 (1998)). Human BLC is 64% homologous to murine BLC. Its receptor is CXCR5. BLC also shares homology with EL-8. BLC recruits B-cells to follicles in secondary lymphoid organs such as the spleen and peyer's patches. BLC is also required for recruitment of B-cells to compartment of the lymph nodes rich in follicular Dendritic Cells (FDCs) (Ansel et al, Nature 406:309-314 (2000)). BLC also induces increased expression of Lymphotoxina1ß2 (LTα1ß2) on the recruited B-cells. This provides a positive feed-back loop, since LTα1ß2 promotes BLC expression (Ansel et al, Nature 405:309-314 (2000)). BLC has also been shown to be able to induce lymphoid neogenesis (Luther et al, Immunity 72:471-481(2000)). It appears that FDCs also express BLC. Thus immunization against BLC may provide a way of treatment against autoimmune diseases where lymphoid neogenesis is involved, such as Rheumatoid synovitis and Rheumatoid arthritis or Type I diabetes. A construct of BLC bearing a C-terminal His-tag has been described, and is functional (Ansel, K.M. et al, J. Exp. Med. 190:1123-1134 (1999)). In one embodiment of the present invention, the composition comprises a linker containing a cysteine residue as second attachment site and being fused at the C-terminus of the BLC sequence. In IL-8, which is homologous to BLC, both N- and C-termini are free. Fusion of an amino acid linker containing a cysteine residue as second attachment site to the N-terminus of BLC leads to one embodiment of the invention. In other embodiments of the present invention, the composition comprises an amino acid linker containing a cysteine and being fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. The genes coding for these specific constructs may be cloned in a suitable expression vector and expressed accordingly. The sequence of human BLC is shown in Accession: NP_006410. Amino acids 1-22 of the sequence are the signal peptide. The mouse sequence is shown in Accession NP_061354. Amino acids 1-21 are the signal peptide. Compositions of the invention with BLC as the antigenic determinant, in some embodiments, use the mature form of the protein for generating the compositions of the invention. In another specific embodiment, the antigenic determinant is Eotaxin Eotaxin is a chemokine specific for Chemokine receptor 3, present on eosinophils, basophils and Th2 cells. Eotaxin seems however to be highly specific for Eosinophils (Zimmerman et al, J. Immunol. 165:5839-46(2000)). Eosinophil migration is reduced by 70% in the eotaxin-1 knock-out mouse, which however can still develop eosinophilia (Rothenberg et al, J. Exp. Med 185: 785-90 (1997)). IL-5 seems to be responsible for the migration of eosinophils from bone-marrow to blood, and eotaxin for the local migration in the tissue (Humbles et al, J. Exp. Med. 186:601-12 (1997)). The human genome contains 3 eotaxin genes, eotaxinl-3. They share 30% homology to each other. Two genes are known so far in the mouse: eotaxin 1 and eotaxin 2 (Zimmerman et al., J. Immunol. 165: 5839-46 (2000)). They share 38% homology. Murine eotaxin-2 shares 59% homology with human eotaxin-2. In the mouse, eotaxin-1 seems to be ubiquitously expressed in the gastro-intestinal tract, while eotaxin-2 seems to be predominantly expressed in the jejunum (Zimmerman et al, J. Immunol. 165:5839-46 (2000)). Eotaxin-1 is present in broncho-alveolar fluid (Teixeira et al, J. Clin. Invest. 100:1657-66 (1997)). Eotaxin has aMW of 8.3 kDa. It is in equilibrium between monomers and dimers over a wide range of conditions, with an estimated Kd of 1.3 mM at 37°C (Crump et al, J. Biol Chem. 273: 22471-9 (1998)). The monomer form is however predominant The structure of Eotaxin has been elucidated by NMR spectroscopy. Binding site to its receptor CCR3 is at the N-terminus, and the region preceding the first cysteine is crucial (Crump et al, J. Biol Chem. 273: 22471-9 (1998)). Peptides of chemokine receptors bound to Eotaxin confirmed this finding. Eotaxin has four cysteines forming two disulfide bridges. Therefore, in one embodiment, the inventive composition comprises an amino-acid linker containing a cysteine residue as second attachment site and being in one embodiment, fused to the C-tenninus of the Eotaxin sequence. In further embodiments, an amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-tenninally of the signal peptide. The genes coding for these specific constructs are cloned in a suitable expression vector. Eotaxin can be chemically synthesized (Clark-Lewis et al, Biochemistry 30:3128-3135 (1991)). Expression in E. coli has also been described for Eotaxin-1, in the cytoplasm (Crump et al, J. Biol Chem. 273:22471-9 (1998)). Expression in E. coli as inclusion bodies with subsequent refolding (Mayer et al, Biochemistry 39: 8382-95 (2000)), and Insect cell expression (Forssmann et al, J. Exp. Med. 185:2171-6 (1997)) have been described for Eotaxin-2, and may, moreover, be used to arrive at the specific embodiments of the invention. In yet another specific embodiment of the invention, the antigenic determinant is Macrophage colony-stimulating factor (M-CSF or CSF-1). M-CSF or CSF-1 is a regulator of proliferation, differentiation and survival of macrophages and their bone-marrow progenitors. The receptor for M-CSF is a cell surface tyrosine kinase receptor, encoded by the protooncogene cFMS. An elevated expression of M-CSF and its receptor has been associated with poor prognosis in several epithelial cancers such as breast, uterine and ovarian cancer. Tumor progression has been studied in a mouse strain resulting from the crossing of a transgenic mouse susceptible to mammary cancer (PyMT) with a mouse containing a recessive null mutation in the csf-1 gene. These mice show attenuated late stage invasive carcinoma and pulmonary metastasis compared to the PyMT mouse (Lin et al,J. Exp.Med 193:727-739 (2001)). The cause seems to be the absence of macrophage recruitment to neoplastic tissues. Subcutaneous growth of Lewis lung cancer is also impaired in csf. 1 null mice. It is postulated that the mechanism of macrophage enhancement of tumor growth would be through angiogenic factors, growth factors and proteases produced by the macrophages. Structural data on the soluble form of M-CSF are available (crystal structure: Pandit et al, Science 258:135 8-62 (1992)), and show that both the N- and C-termini of the protein are accessible. However, the N-terminus is close to the site of interaction with the receptor. In addition, M-CSF is present both in a soluble and cell surface form, where the transmembrane region is at its C-terminus. Therefore certain embodiment of the present invention comprise an amino acid linker containing a cysteine and being, in one embodiment, added at the C-terminus of M-CSF or fragments thereof, at the C-terminus of the soluble form of M-CSF. In other embodiments, the amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein or of the soluble form of the protein, or inserted at the N-terminus of the sequence of the mature form of the protein or of the soluble form of the protein, C-terminally of the signal peptide. M-CSF is a dimer, where the two monomers are linked via an interchain disulfide bridge. An expression system in E. coli has been described for an N-terminal 149 amino acid fragment (functional) of M-CSF (Koths et al, Mol Reprod Dev. 46:31-37 (1997)). This fragment of M-CSF, modified as outlined above, represents a one antigenic determinant in accordance with the embodiments of the invention. The human sequence is shown in Accession: NP_000748. Other antigenic determinants of the present invention comprise the N-terminal fragment consisting of residue 33 -181 or 33 -185 of the above sequence, corresponding to the soluble form of the receptor. The mouse sequence is shown in Accession. NP_031804. The mature sequence starts at amino acid 33. Thus, one antigenic determinant in accordance with the present invention comprises amino-acid 33 -181 or 33 -185. In one embodiment, the antigenic determinant is Resistin (Res). Passive immunization studies were performed with a rabbit polyclonal antibodies generated against a fusion protein of mouse Resistin (mRes) fused to GST, expressed in bacteria. This passive immunization lead to improved glucose uptake in an animal obesity/ Type II diabetes model (Steppan et al, Nature 409:307-12 (2001)). Resistin (Res) is a 114 aa peptide hormone of approximately 12 KD. It contains 11 cysteine of which the most N-terminal one was shown to be responsible for the dimerisation of the protein and the other 10 are believed to be involved in intramolecular disulfide bonds (Banerjee and Lazar, J. Biol Chem. 276: 25970-3 (2001)). Mutation of the first cysteine to alanine abolishes the dimerisation of mRes. mRes with a FLAG tag at its C-terminus remains active in an animal model (Steppan et al, Nature 409: 307-12 (2001)). Similarly a C-terminally HA taged (Haemagglutinin tag) version of resistin was shown to be active in a tissue culture assay (Kim et al, J. Biol Chem. 276:11252-6 (2001)). Therefore, in one embodiment, the present compositions comprise an amino-acid linker containing a cysteine residue as second attachment site and being fused at the C-terminus of the resistin sequence. In another embodiment, the amino acid linker containing a cysteine is fused to the N-terminus of the sequence corresponding to the sequence of the processed protein, or inserted at the N-terminus of the sequence of the mature form of the protein, C-terminally of the signal peptide. In one embodiment of the present invention, MRes or huRes may also be expressed as Fc fusion molecules with a protease cleavage site inserted between Resistin and the Fc part of the construct, such as C-terminally to one or more cysteine residues of the hinge region of the Fc part of the fusion protein in a eukaryotic expression system, or such as according to the descriptions herein. Cleavage of the fusion protein releases Resistin additionally comprising either an aminoacid linker containing a cysteine residue or part or all of the hinge region of the Fc part of the fusion protein which comprises a cysteine residue at its C-terminus, which is suitable for coupling to AP205 VLP. The human Resistin sequence is shown in Accession AF323081. The mouse sequence is shown in Accession AF323080. A favored embodiment of the invention is human resistin protein fused at its C-terminus to an amino acid linker containing a cysteine residue. Human resistin construct can be generated according to the teachings disclosed herein and by comparing murine and human Resistin sequences in a protein sequence alignment to identify the part of the sequence of human Resistin to be cloned into vectors herein or in other suitable expression vectors. Example of human resistin constructs suitable for generating compositions of the inventions are human resistin-C-Xa, human resistin-C-EK and human resistin-C. Human Resistin constructs so generated are a one embodiment of the invention. Vaccination against Resistin using the aforementioned compositions of the invention may thus provide a way of treating Type II Diabetes and obesity. In another embodiment the antigenic determinant is Lymphotoxin-p. Immunization against lymphotoxin-p may be useful in treating Prion mediated disease. Prions are cellular proteins existing in most mammalian species. Prion proteins exist in two forms, a normally folded form that is usually present in healthy individuals (PrPc) and a misfolded form that causes disease (Prp8c). The current prion hypotheses postulates that the misfolded prion form PrpSc can catalyse the refolding of healthy prion PrPc into disease causing PrpSc (A. Aguzzi, Haematologica 85,3-10 (2000)). In some rare instances, this transition may also occur spontaneously, causing classical CJD in humans. Some mutations in PrPc are associated with an increase in this spontaneous transition, causing the various forms of familial CJD. However, PrpSc may also be infectious and may be transmitted by blood transfusion or via the food chain. The latter form of prion mediated disease is known as Kuru Kuru and used to occur in human cannibals. However, since species that are feeding on their own individuals are not abundant, this form of orally transmitted disease was too rare to be documented for other species. The massive feeding of cows with beef-products throughout Europe changed the situation and numbers of cows infected with a transmissible form of BSE-causing PrpSc, dramatically increased in recent years, afflicting hundreds of thousands of cows. This sudden appearance of massive numbers of BSE-diseased cows caused great fear in the human population mat a similar disease may be induced in humans. Indeed, in 1996, the first case of a variant form of CJD was reported that could be attributed to the consumption of Prp80 infected beef. Until now, this fear has further increased, since the number of infected humans has constantly increased during the following years and no cure is in sight Moreover, since sheep succumb to a prion-mediated disease called scrapie and since other mammalian species can be infected with Prp80, it is possible that BSE-like diseases may occur also in other species. Scrapie (a prion-mediated disease) agent replication is believed to take mainly place in lymphoid tissues and was shown to depend on prion-protein expressing follicular dendritic cells (FDCs) (Brown et al, Nature Med. 11:1308-1312 (1999)). The mechanism of prion transmission has been studied in great detail. It is now clear that prions first replicate in the lymphoid organs of infected mice and are subsequently transported to the central nervous system. It was shown that mice lacking functional follicular dendrite cells show an impaired prion replication in spleens and a (small) retardation of neuroinvasion (Montrasio et al, Science 288:1257-1259 (2000)). This was achieved by injecting the mice with a soluble lymphotoxin-p receptor-Fc-fusion protein (LTßR-Fc). This soluble receptor construct inhibits the development of FDCs by interfering with the crucial interaction of lymphotoxin-p on T, B or NK cells with the lymphotoxin-p receptor on the FDC precursor ceils. FDCs are a poorly studied cell type but it is now clear that they depend upon the production of lymphotoxin and/or TNF by B cells for their development (F. Mackay, J. L. Browning, Nature 395,26-27 (1998)). Indeed, mice deficient for lymphotoxin do not exhibit FDCs (M. S. Matsumoto, et al., Science 264,703-707 (1996)). In addition to FDCs, antibodies may also play a role in disease progression (S. Brandner, M. A. Klein, A. Aguzzi, Transfus Clin Biol 6,17-23(1999)). Thus, vaccination against lymphotoxin-p (also called TNF), LTα or LTß receptor, thereby eliminating FDCs from lymphoid organs, may provide a vaccine for treatment or prevention of Creutzfeld-Jakob (variant form) or other prion-mediated diseases such as bovine spongioform encephalopathy (BSE) and thus prevent prion replication and neuroinvasion. Immunization against Lymphotoxin-P may also provide a way of treating diabetes. Transgene expression of soluble LTßR-Fc fusion protein in nonobese diabetic NOD mice blocked diabetes development but not insulitis (Ettinger et al., J. Exp. Med. 193:1333-40 K(2001)). Wu et al (J.Exp.Med. 193:1327-32(2001))alsousedNOD mice to study the involvement of lymphotoxin-p, but instead of transgenic animals they did inject the LTpR-Fc fusion protein. They saw a strong inhibition of diabetes development and inhibition of insulitis. Most interestingly, they could even reverse preexisting insulitis by the fusion protein treatment. In the pancreas the formation of lymphoid follicular structures could thus be reversed. Vaccination against lymphotoxin-P may thus provide a way of treatment against type-I diabetes. In one embodiment, the inventive composition comprises an amino acid linker containing a cysteine and being added to the N-terminus of the sequence corresponding to the processed form of lymphotoxin-p, or inserted between the N-terminus of the sequence corresponding to the mature form of the protein, and the signal peptide, C-terminally to the signal peptide. In related embodiments of the invention, the extracellular part of lymphotoxin-p is expressed as a fusion protein either with glutathione-S-transferase, fused N-terminally to lymphotoxin-p, or with a 6 histidine-tag followed by a myc-tag, fused again N-terminally to the extracellular part of lymphotoxin-p. An amino acid spacer containing a protease cleavage site as well as a linker sequence containing a cysteine as attachment site, C-terminally to the protease cleavage site, are fused to the N-terminus of the sequence of the extracellular part of lymphotoxin-p. In one embodiment the extracellular part of lymphotoxin-P consists of fragments corresponding to amino acids 49-306 or 126-306 of lymphotoxin-p. These specific compositions of the invention may be cloned and expressed in the pCEP-Pu eukaryotic vector. In certain embodiments, the inventive compositions comprise an aminoacid linker containing a cysteine residue suitable as second attachment site, and being fused to the C-terminus of lymphotoxin-p or lymphotoxin-p fragments. In a particularly favored embodiment, the amino acid sequence LACGG, comprising the amino acid linker ACGG which itself contains a cysteine residue for coupling to AP205 VLP is fused to the N-terminus of the extracellular part of lymphotoxin-P or of a fragment of the extracellular part of lymphotoxin-p, yielding the proteins human C-LTß49-306 and human C-LTP126-306 after cleavage with enterokinase of the corresponding fusion proteins expressed either in vector pCEP-SP-GST-EK or vector pCP-SP-his-myc-EK. In one embodiment, me antigen or antigenic determinant is the prion protein, fragments thereof and in particular peptides of the prion protein. In an embodiment of the invention, the antigenic determinant is the prion protein or fragments thereof. Immunization against prion protein may provide a way of treatment or prevention of Creutzfeld-Jakob (variant form) or other prion-mediated diseases. Murine peptides corresponding to fragments of the murine prion protein and of sequence CSAMSRPMIHFGNDWEDRYYRENMYR (SEQ ID NO: 17) ("cprplong") and CGNDWEDRYYRENMYR ("cprpshort") (SEQ ID NO: 18) comprise an added N-terminal cysteine residue for for chemical coupling to AP20S VLP and lead to one embodiment of the invention. In one embodiment the prion protein is the human prion protein. Guidance on how to modify human prion protein for association with the AP205 VLP is given throughout the application. Mouse prion protein constructs are disclosed, and human prion protein constructs can also be generated. Further constructs comprise the whole human prion protein sequence, and other fragments of the human prion protein, which are further compositions of the invention. Immunization against prion protein may provide a way of treatment or prevention of Creutzfeld-Jakob (variant form) or other prion-mediated diseases. Immunization using the compositions of the invention comprising the prion protein may provide a way of treatment against prion mediated diseases in other animals. The peptides of the human prion protein corresponding to the murine peptides described above and of amino acid sequence CSAMSRPIIHFGSDYEDRYYRENMHR ("human cprplong") (SEQ ID NO: 19) and CGSDYEDRYYRENMHR ("human cprpshort") (SEQ ID NO: 20) lead to embodiments of the invention. These peptides comprise an N-terminal cysteine residue added for coupling to AP205 VLP. Corresponding bovine and sheep peptides are CSAMSRPLIHFGNDYEDRYYRENMHR ("bovine cprplong") (SEQ ID NO: 21) and CGNDYEDRYYRENMHR ("bovine cprpshort") (SEQ ID NO: 22) CSAMSRPLIHFGNDYEDRYYRENMYR ("sheep cprplong") (SEQ ID NO: 23) and CGNDYEDRYYRENMYR ("sheep cprpshort") (SEQ ID NO: 24), all leading to embodiments of the invention. In one embodiment of the invention, the antigenic determinant is tumor necrosis factor a (TNF-α), fragments thereof or peptides of TNF-a. In particular, peptides or fragments of TNF-α can be used to induce a self-specific immune response directed towards the whole protein by immunizing a human or an animal with vaccines and compositions, respectively, comprising such peptides or fragments in accordance with the invention. The following murine peptides are the murine homologs to human peptides that have been shown to be bound by antibodies neutralizing the activity of TNF-a (Yone et al J. Biol. Chem.270: 19509-19515) and were, in another embodiment of the invention, modified with cysteine residues for coupling to AP205 VLP. MuTNFa peptide; the sequence CGG was added at the N-terminus of the epitope consisting of amino acid residues 22-32 of mature murine TNF-a, giving the sequence: CGGVEEQLEWLSQR (SEQ ID NO: 25). 3'TNF II peptide; the sequence GGC was fused at the C-terminus of the epitope consisting of amino acid residues 4-22 of mature murine TNF-a and glutamine 21 was mutated to glycine. The sequence of the resulting peptide is: SSQNSSDKPVAHVYANHGVGGC (SEQ ID NO: 26). 5'TNF II peptide: a cysteine residue was fused to the N-terminus of the epitope consisting of amino acid residues 4-22 of mature murine TNF-a and giutamine 21 was mutated to glycine. The sequence of the resulting peptide is: CSSQNSSDKPVAHWANHGV (SEQ ID NO: 27). The corresponding human sequence of the 4-22 epitope is SSRTPSDKPVAHVVANPQAEGQ (SEQ ID NO: 28). As for the murine sequence a cysteine is, in one embodiment, fused at the N-terminus of the epitope, or the sequence GGC is fused at the C-terminus of the epitope for covalent coupling to AP205 VLP according to the invention. It is, however, within the scope of the present invention that other cysteine containing sequences are fused at the N- or C-termini of the epitopes. In general, one or two glycine residues are, in one embodiment, inserted between the added cysteine residue and the sequence of the epitope. Other amino acids may, however, also be inserted instead of glycine residues, and these amino acid residues include small amino acids such as serine. In a further preferred embodiment of the inventive composition, the antigen or antigenic determinant is tumor necrosis factor a (TNF-a), fragments or muteins thereof or peptides of TNF -a or fragments or muteins thereof, wherein said antigen or antigenic determinant with said second attachment site has an amino acid sequence selected from the group consisting of: a) the amino acid sequence of CSSRTPSDKPVAHWANPQAEGQ (SEQ ID NO: 100); b) the amino acid sequence of SSRTPSDKPVAHWANPQAEGQGGC (SEQ ID NO: 101); and c) the amino acid sequence of CGGQLQWLNRRANA (SEQ ID NO: 102). The human sequence corresponding to amino acid residues 22-32 is QLQWLNRRANA (SEQ ID NO: 29). In one related embodiment, the sequence CGG is fused at the N-terminus of the epitope for covalent coupling to AP205 VLP according to the invention. Other TNF-α epitopes suitable for using in the present invention have been described and are disclosed for example by Yone et al. {J. Biol. Chem.270:19509-19515). The invention further includes compositions which contain mimotopes of the antigens or antigenic determinants described herein. One specific composition of the invention comprises an antibody or an antibody fragment presented on a virus-like particle for induction of an immune response against that antibody. In one embodiment, antibodies or antibody fragments which are produced by lymphoma cells, are selected for attachment to the virus-like particle for immunization in order to induce a protective immune response against the lymphoma. In other further embodiments, an antibody or antibody fragment mimicking an antigen is attached to the AP205 VLP. The mimicking antibody or antibody fragment is generated by immunization and subsequent isolation of the mimicking antibody or antibody fragment, or by any known method known to the art such as e.g. hybridoma technology (Gherardi, E. et al., J. Immunol. Methods 126:61-68 (1990)), phage display (Harrison et al, Methods Enzymol 267:83-109 (1996)), ribosome display (Hanes, J. et al.Nat. Biotechnol 18:1287-1292 (2000), yeast two-hybrid (Visintin,M. eta/., Proc. Natl. Acad Set. USA 96:11723-11728 (1999)), yeast surface display (Boder, ET. & Wittrup, KD. Methods. Enzym. 328: 430-444 (2000)), bacterial surface display (Daugherty,PS. et al, ProtelnEng. 12:613-621 (1999)). The mimicking antibody may also be isolated from an antibody library or a naive antibody library using methods known to the art In a further embodiment, an antibody recognizing the combining site of another antibody, i.e. an anti-idiotypic antibody, further called the immunizing antibody, is used. The antibody recognized by the anti-idiotypic antibody will be further referred to as the neutralizing antibody. Thus, by immunizing against the anti-idiotypic antibody, molecules with the specificity of the neutralizing antibody are generated in situ; we will further refer to these generated antibodies as the induced antibodies. In another embodiment, the immunizing antibody is selected to interact with a ligand molecule of the target molecule against which immunization is sought The ligand molecule may be any molecule interacting with the target molecule but will, in one embodiment, preferentially interact with the site of the target molecule against which antibodies should be generated for inhibition of its function. The ligand molecule may be a natural ligand of the target molecule, or may be any engineered, designed or isolated ligand having suitable binding properties. The immunizing antibodies may be of human origin, such as isolated from a naive or immune human antibody library, or may have been isolated from a library generated from another animal source, for example of murine origin. Coupling of the antibody or antibody fragment to AP205 VLP is achieved either by limited reduction of exposed disulfide bridges (for example of the interchain disulfide bridge between CH1 and CK or C in a Fab fragment) or, in another embodiment, by fusion of a linker containing a cysteine residue at the C-terminus of the antibody or antibody fragment. In a further embodiment, a linker containing a cysteine residue is fused to the N-terminus of the antibody or antibody fragment for attachment to a VLP or pilus protein. A number of vaccine compositions which employ mimotopes are known in the art, as are methods for generating and identifying mimotopes of particular epitopes. For example, Arnon et al, Immunology 101:555-562 (2000), the entire disclosure of which is incorporated herein by reference, describe mimotope peptide-based vaccines against Schistosoma mansoni. The mimotopes uses in these vaccines were obtained by screening a solid-phase 8-mer random peptide library to identify mimotopes of an epitope recognized by a protective monoclonal antibody against Schistosoma mansoni. Similarly, Olszewska et al, Virology 272:98-105 (2000), the entire disclosure of which is incorporated herein by reference, describe f mice. In addition, Zuercher et al., Eur. J. Immunol. 50:128-135 (2000), the entire disclosure of which is incorporated herein by reference, describe compositions and methods for oral anti-IgE immunization using epitope-displaying phage. In particular, epitope-displaying M13 bacteriophages are employed as carriers for an oral anti-IgE vaccine. The vaccine compositions tested contain mimotopes and epitopes of the monoclonal anti-IgE antibody BSW17. Embodiments of the invention include vaccine compositions which contain mimotopes that elicit immunological responses against particular antigens, as well as individual mimotope/AP205 VLP conjugates which make up these vaccine compositions, and the use of these vaccine compositions to elicit immunological responses against specific antigens or antigenic determinants. Mimotopes may also be polypeptides, such as anti-idiotypic antibodies. Therefore, in a further embodiment of the invention, the antigen or antigenic determinant is an anti-idiotypic antibody or anti-idiotypic antibody fragment. The invention further includes compositions which contain mimotopes of the antigens or antigenic determinants described herein. Mimotopes of particular antigens may be generated and identified by any number ofmeans including the screening of random peptide phage display libraries {see, e.g., WO 97/31948, the entire disclosure of which is incorporated herein by reference). Screening of such libraries will often be performed to identify peptides which bind to one or more antibodies having specificity for a particular antigen. Mimotopes suitable for use in vaccine compositions of the invention may be linear or circular peptides. Mimotopes which are linear or circular peptides may be linked to non-natural molecular scaffolds or core particles and VLPs, respectively, by a bond which is not a peptide bond. As suggested above, a number of human IgE mimotopes and epitopes have been identified which elicit immunological responses against human IgE molecules. (See, e.g., WO 97/31948.) Thus, in certain embodiments, vaccine compositions of the invention include compositions which elicit an immunological response against immunoglobin molecules (e.g., IgE molecules). Peptides which can be used to elicit such immunological responses include proteins, protein subunits, domains of IgE molecules, and mimotopes which are capable of eliciting production of antibodies having specificity for IgE molecules. Generally, portions of IgE molecules used to prepare vaccine compositions will be derived from IgE molecules of the species from which the composition is to be administered. For example, a vaccine composition intended for administration to humans will often contain one or more portions of the human IgE molecule, and/or one or more mimotopes which are capable of eliciting immunological responses against human IgE molecules. In specific embodiments, vaccine compositions of the invention intended for administration to humans will contain at least one portion of the constant region of the IgE heavy chain set out in Accession No. AAB59424. In more specific embodiments, IgE peptides used to prepare vaccine compositions of the invention comprise, or alternatively consist of, peptides having the following amino acid sequences: CGGVNLTWSRASG (SEQ ID NO: 30). In additional specific embodiments, vaccine compositions of the invention will contain at least one mimotope which is capable of eliciting an immune response that results in the production of antibodies having specificity for a particular antigen. Examples of mimotopes of IgE suitable for use in the preparation of vaccine compositions of the invention include peptides having the following amino acid sequences: (Sequence Removed) Preparation of vaccines and immunogens VLPs of bacteriophage AP205 are useful in generating vaccine constructs, and render antigens attached to it highly immunogenic. The present invention provides methods of attachment of antigens to the AP205 VLP. In one embodiment the antigen is attached to the VLP by way of chemical cross-linking, using a heterobifunctional cross-linker. Several hetero-bifunctional cross-linkers are known to the art In the some embodiments, the hetero-bifunctional cross-linker contains a functional group which can react with the side-chain amino group of lysine residues of the VLP, and functional group which can react with a cysteine residue naturally present, made available for reaction by reduction, or engineered on the antigen and optionally also made available for reaction by reduction. The first step of the procedure, called the derealization, is the reaction of the VLP with the cross-linker. The product of this reaction is an activated VLP, also called activated carrier. In the second step, unreacted cross-linker is removed using usual methods such as gel filtration or dialysis. In the third step, the antigen is reacted with the activated VLP, and this step is called the coupling step. Unreacted antigen may be optionally removed in a fourth step. Several hetero-bifunctional cross-linkers are known to the art. These include the cross-linkers SMPH (Pierce), Sulfo-MBS, Sulfo-EMCS, Sulfo-GMBS, Sulfo-SIAB, Sulfo-SMPB, Sulfo-SMCC, SVSB, SIA and other cross-linkers available, for example from the Pierce Chemical Company (Rockford, IL, USA), and having one functional group reactive towards amino groups and one functional group reactive towards cysteine residues. The above mentioned cross-linkers all lead to formation of a thioether linkage. Another class of cross-linkers suitable in the practice of the invention is characterized by the introduction of a disulfide linkage between the antigen and the VLP upon coupling. Cross-linkers belonging to this class include for example SPDP and Sulfo-LC-SPDP (Pierce). The extent of derivatizationof the VLP with cross-linker can be influenced by varying experimental conditions such as the concentration of each of the reaction partners, the excess of one reagent over the other, the pH, the temperature and the ionic strength, as is well known from reaction theory in the field of organic chemistry. The degree of coupling, i.e. the amount of antigens per subunits of AP205 VLP can be adjusted by varying the experimental conditions described above to match the requirements of the vaccine. Solubility of the antigen may impose a limitation on the amount of antigen that can be coupled on each subunit, and in those cases where the obtained vaccine is insoluble, reducing the amount of antigens per subunit is beneficial. One method of attachment of antigens to AP205 VLP, is the linking of a lysine residue on the surface of the AP205 VLP with a cysteine residue on the antigen. In some embodiments, engineering of an amino acid linker containing a cysteine residue to the antigen for coupling to AP205 VLP is required. Alternatively, a cysteine may be introduced either by insertion or mutation within the antigen. In a preferred embodiment of the present invention, the composition comprsises an amino acid linker. Preferably, said amino acid linker is bound to the at least one antigen, antigenic determinant and organic molecule, respectively, by way of at least one covalent bond. The selection of the amino acid linker will be dependent on the nature of the antigen, on its biochemical properties, such as pi, charge distribution, or glycosylatioa In general, flexible amino acid linkers are favored embodiments. Examples of amino acid linkers are the hinge region of Immunoglobulins, glycine serine linkers (GGGGS)n (SEQ ID NO: 49), and glycine linkers (G)n all further containing a cysteine residue as second attachment site and optionally further glycine residues. (The following are examples of such amino acid linkers: (Sequence Removed) For peptides, GGCG (SEQ ID NO: 58), GGC or GGC-NH2 ("NH2" stands for amidation) linkers at the C-terminus of the peptide, or CGG at its N-terminus have shown to be useful. In some embodiments, glycine residues will be inserted between bulky amino acids and the cysteine to be used as second attachment site. Preferred embodiments of the amino acid linker are selected from the group consisting of: (a) CGG; (b) N-terminal gamma 1-linker, (c) N-terminal gamma 3-linker, (d) Ig hinge regions; (e) N-terminal glycine linkers; (f) (G)kC(G)a with n=0-12 and k=0-5 (SEQ ID NO: 93); (g) N-terminal glycine-serine linkers; (h) (G)kC(G)m(S)i(GGGGS)n with n=0-3, k=0-5, m=0-10,1=0-2 (SEQ ID NO: 94); (i) GGC; (k) GGC-NH2; (1) C-terminal gamma 1-linker; (m) C-terminal gamma 3-linker; (n) C-terminal glycine linkers; (o) (G)nC(G)k with n=0-12 and k=0-5 (SEQ ID NO: 95); (p) C-terminal glycine-serine linkers; (q) (G)m(S)i(GGGGS)n(G)0C(G)k with n=0-3, k=0-5, m=0-10,1=0-2, and o=0-8 (SEQ ID NO: 96). In certain embodiments, the antigen or antigen determinant comprises a single second attachment site or a single reactive attachment site capable of association with the first attachment sites on the AP205 VLPs or VLP subunits, respectively. This ensures a defined and uniform binding and association, respectively, of the at least one, but typically more than one, preferably more than 10,20,40,80,120 antigens to the AP205 VLP. The provision of a single second attachment site or a single reactive attachment site on the antigen, thus, ensures a single and uniform type of binding and association, respectively leading to a very highly ordered and repetitive array. For example, if the binding and association, respectively, is effected by way of a lysine- (as the first attachment site) and cysteine- (as a second attachment site) interaction, it is ensured, in accordance with this preferred embodiment of the invention, that only one cysteine residue per antigen, independent whether this cysteine residue is naturally or non-naturally present on the antigen, is capable of binding and associating, respectively, with the AP205 VLP and the first attachment site of the AP205 VLP, respectively. The cysteine residue present on the antigen has to be in its reduced state to react with the hetero-bifunctional cross-linker on the activated VLP, mat is a free cysteine or a cysteine residue with a free sulfhydryl group has to be available. In the instance where the cysteine residue to function as second attachment site is in an oxidized form, for example if it is forming a disulfide bridge, reduction of this disulfide bridge with e.g. DTT, TCEP or p-mercaptoethanol is required. Attachment of the antigen to the AP205 VLP by using a hetero-bifunctional cross-linker according to the method described above, allows coupling of the antigen to the AP205 VLP in an oriented fashion. Other methods of binding the antigen to the AP205 VLP include methods wherein the antigen is cross-linked to the AP205 VLP using the carbodiimide EDC, and NHS. The antigen or antigen determinant may also be first thiolated through reaction, for example with SATA, SATP or iminothiolane. The antigen or antigen determinant, after deprotection if required, may then be coupled to the AP205 VLP as follows. After separation of the excess thiolation reagent, the antigen or antigen determinant is reacted with the AP205 VLP previously activated with a hetero-bifunctional cross-linker comprising a cysteine reactive moiety, and therefore displaying at least one or several functional groups reactive towards cysteine residues, to which the thiolated antigen or antigen determinant can react, such as described above. Optionally, low amounts of a reducing agent are included in the reaction mixture. In other methods, the antigen is attached to the AP20S VLP using a homo-bifunctional cross-linker such as glutaraldehyde, DSG, BM[PEO]4, BS3, (Pierce Chemical Company, Rockford, IL, USA) or other known homo-bifunctional cross-linkers whith functional groups reactive towards amine groups or carboxyl groups of the AP205 VLP. In a further embodiment, the antigen or antigen determinant is bound to the AP205 VLP through modification of the carbohydrate moieties present on glycosylated antigen or antigen determinant and subsequent reaction with the AP205 VLP. In one embodiment, the glycosylated antigen or antigen determinant is reacted with sodium periodate in a mild oxidation reaction of the carbohydrate moiety, to yield an activated antigen or antigen determinant with one or more aldehyde functional groups. The so activated antigen or antigen determinant is separated from excess sodium periodate, and further reacted with the AP205 VLP, wherein lysine residues of the AP205 VLP or of at least one AP205 VLP subunit are reacting with the previously formed aldehyde functional group on the antigen or antigen determinant, for example as described by Hermanson, G.T. inBioconjugate Techniques, Academic Press Inc., San Diego, CA, USA. Self polymerization of the activated antigen or antigen determinant may be controlled by adjusting the pH as described in the aforementioned publication. The formed Schiff base is preferably further reduced with sodium cyanoborohydride, which is subsequently removed by gel filtration or dialysis. Alternatively, carboxyl groups of the AP205 VLP or of at least one of the AP205 VLP subunit may be reacted with EDC and a dihydrazyde, such as adipic acid dihydrazyde, to yield a hydrazide moiety available for reaction with the one or more aldehyde functional groups present on the activated antigen or antigen determinant The so formed hydrazone may be further reduced with sodium cyanoborohydride. Alternatively, the activated antigen or antigen determinant with one or more aldehyde functional groups is reacted with cysteamine, resulting in the introduction of a cysteine group in the antigen or antigen determinant Additional cross-linking methods and cross-linkers, suitable for binding an antigen or antigen determinant to a AP205 VLP, as well as guidance on performing the coupling reactions and on the use of chemical cross-linkers and chemical cross-linking procedures can be found in Hermanson, G.T. in Bioconjugate Techniques, Academic Press Inc., San Diego, CA, USA. Other methods of binding the VLP to an antigen include methods where the VLP is biotinylated, and the antigen expressed as a streptavidin-fusion protein, or methods wherein both the antigens and the VLP are biotinylated. In this case, the antigen may be first bound to streptavidin or avidin by adjusting the ratio of antigen to streptavidin such that free binding sites are still available for binding of the VLP, which is added in the next step. Alternatively, all components may be mixed in a "one pot" reaction. Other ligand-receptor pairs, where a soluble form of the receptor and of the ligand is available, and are capable of being cross-linked to the VLP or the antigen, may be used as binding agents for binding the antigen to the VLP. In a preferred embodiment of the present invention, said first and/or said second attachment sites are selected from the group consisting of: (a) an antigen and an antibody or antibody fragment thereto; (b) biotin and avidim strepavidin and biotin; (c) a receptor and its ligand; (d) a ligand-binding protein and its ligand; (e) interacting leucine zipper polypeptides; (f) an amino group and a chemical group reactive thereto; (g) a carboxyl group and a chemical group reactive thereto; (h) a sulfhydryl group and a chemical group reactive thereto; and (i) a combination thereof. Immune Responses The nature or type of immune response is not a limiting factor of this disclosure. The desired outcome of a therapeutic or prophylactic immune response may vary according to the disease, according to principles well known in the art For example, an immune response against an infectious agent may completely prevent colonization and replication of an infectious agent, affecting "sterile immunity" and the absence of any disease symptoms. However, a vaccine against infectious agents may be considered effective if it reduces the number, severity or duration of symptoms; if it reduces the number of individuals in a population with symptoms; or reduces the transmission of an infectious agent Similarly, immune responses against cancer, allergens or self antigens may completely treat a disease, may alleviate symptoms, or may be one facet in an overall therapeutic intervention against a disease. For example, the stimulation of an immune response against a cancer may be coupled with surgical, chemotherapeutic, radiologic, hormonal and other immunologic approaches in order to affect treatment. Furthermore, it may be desired to stimulate different types of immune response depending on the disease, and according to principles known in the art. It is well known, for example, that some immune responses are more appropriate for a particular antigen than other immune responses. Some immune responses are, indeed, inappropriate and can cause pathology, such as pathologic inflammation in response to infection, allergies and autoimmune disease, further described herein. While not desiring certain specific immune responses, the present invention stimulates immune responses towards therapeutic or prophylactic goals. A further particular embodiment of the invention includes the generation of an immune response able to counter the effects of a pathologic immune response. The nature of the immune response can be affected by the nature of the antigen, route of introduction into the body, dose, dosage regimen, reptitive nature of the antigen, host background, and signalling factors of the immune system. Such knowledge is well known in the art. As such, an immune response may be tailored by the application of both art known theory and routine experimentation. While not wishing to be bound by theory, the current invention presents particular novel and surprising advantages as a component of a pharmaceutical composition to generate an immune response, and particularly as a vaccine. Firstly, other carriers known in the art including BSA, keyhole limpet hemocyanin, tetanus toxoid, bacterial outermembrane proteins, cholera toxin, Pseudomonas aeruginosa Exotoxin A and bacterial pili may be inappropriate for use in an individual, and in particular a human. The aforementioned carriers may induce allergic reactions, or stimulate pathologic immune responses (for example, cholera toxin, KLH, BSA). The aforementioned carriers may require the presence of adjuvants such as complete Freunds adjuvant, now considered innappropriate for use in humans. A number of the carriers may be components of current vaccines (for example, tetanus toxoid, cholera toxin, Exotoxin A), or represent antigens that are commonly encountered (for example, bacterial pili, exotoxin A, outermembrane proteins). As such an individual may possess a high level of pre-existing immunity to these carriers, such that immunization with an antigen-carrier conjugate will induce a relatively greater immune response to the carrier than to the novel antigen. For these reasons, individually or as a whole, the use of AP205 as a carrier protein may represent a useful improvement over current carrier proteins. An AP205-DerPl conjugate composition is able to stimulate an immune response against DerP1 without the use of complete Freund's adjuvant and without evidence of pathologic immune responses. In the use of AP205 as a carrier protein, it is possible that AP205-antigen antigens conjugated to AP205 can be taken up by antigen presenting cells and thereby stimulate T-cell_help to induce immune response. Further, haptens, which are normally non immunogenic, may be coupled to AP205 thereby generating an immune response against such haptens. A further advantageous feature of the invention is that antigens may be presented on the surface of a VLP in regular, repetitive arrays that are able to induce efficient immune responses both with and without T-cell help. This feature of the invention is particularly advantageous. The present invention thus provides methods for improving the efficiency of vaccination, particularly against self-antigens, by increasing the degree of repetitiveness of the antigen to be used for immunization, through binding of the antigen to the AP205 VLP. Compositions, Vaccines, and the Administration Thereof, and Methods of Treatment The invention provides vaccine compositions which may be used for preventing and/or attenuating diseases or conditions. The invention further provides vaccination methods for preventing and/or attenuating diseases or conditions in individuals. In one embodiment, the invention provides vaccines for the prevention of infectious diseases in a wide range of species, particularly mammalian species such as human, monkey, cow, dog, cat, horse, pig, etc. Vaccines may be designed to treat infections of viral etiology such as HIV, influenza, Herpes, viral hepatitis, Epstein Barr, polio, viral encephalitis, measles, chicken pox, etc.; or infections of bacterial etiology such as pneumonia, tuberculosis, syphilis, etc.; or infections of parasitic etiology such as malaria, trypanosomiasis, leishmaniasis, trichomoniasis, amoebiasis, etc. In another embodiment, the invention provides vaccines for the prevention and treatment of cancer in a wide range of species, particularly mammalian species such as human, monkey, cow, dog, cat, horse, pig, etc. Vaccines may be designed to treat all types of cancer: lymphomas, carcinomas, sarcomas, melanomas, etc. In another embodiment of the invention, conjugates, compositions and methods of the invention may be used in the design of vaccines for the treatment of allergies. Antibodies of the IgE isotype are important components in allergic reactions. Mast cells bind IgE antibodies ontlieir surface and release histamines and other mediators of allergic response upon binding of specific antigen to the IgE molecules bound on the mast cell surface. Inhibiting production of IgE antibodies, therefore, is a promising target to protect against allergies. This should be possible by attaining a desired T helper cell response. T helper cell responses can be divided into type 1 (TH1) and type 2 (TH2) T helper cell responses (Romagnani, Immunol. Today 18:263-266 (1997)). TH1 cells secrete interferon-gamma and other cytokines. In contrast, a critical cytokine produced by TH2 cells is IL-4, which drived B cells to produce IgE. In many experimental systems, the development of TH1 and TH2 responses is mutually exclusive sinceTHl cells suppress the induction of TH2 cells and vice versa. Thus, antigens that trigger a strong THI response simultaneously suppress the development of TH2 responses and hence the production of IgE antibodies. It is finding of the present invention that AP205 VLP induce a Tn1-type immune response. Thus, by using the processes of the invention, AP205 VLPs can be decorated with various allergens and used for immuirization. Due to the coupling of the allergen to AP205 VLP, a TH1 response will be elicited, "protective" IgG antibodies will be produced, and the production of IgE antibodies which cause allergic reactions will be prevented. Since the allergen is presented by VLPs which are recognized by a different set of helper T cells than the allergen itself, it is likely that the allergen-specific IgG antibodies will be induced even in allergic individuals harboring pre-existing TH2 cells specific for the allergen. The presence of high concentrations of IgG antibodies may prevent binding of allergens to mast cell bound IgE, thereby inhibiting the release of histamine. Thus, presence of IgG antibodies may protect from IgE mediated allergic reactions. Typical substances causing allergies include but are not limited to: pollens (e.g. grass, ragweed, birch or mountain cedar pollens), house dust, mites, mammalian epidermal allergens and animal danders, mold and fungus, insect bodies and insect venom, hair, saliva, serum, feathers, food or drugs (e.g., penicillin) See Shough, H. et al, REMINGTON'S PHARMACEUTICAL SCIENCES, 19th edition, (Chap. 82), Mack Publishing Company, Mack Publishing Group, Easton, Pennsylvania (1995), the entire contents of which is hereby incorporated by reference. .

Having now described the present invention in detail, the same will be more clearly understood by reference to the following examples, which are included herewith for purposes of illustration only and are not intended to be limiting of the invention. EXAMPLES EXAMPLE 1: Cloning of the AP205 Coat Protein gene The cDNA of AP205 coat protein (CP) was assembled from two cDNA fragments generated from phage AP205 RNA by using a reverse transcription-PCR technique and cloning in the commercial plasmid pCR 4-TOPO for sequencing. Reverse transcription techniques are well known to those of ordinary skill in the relevant art. The first fragment, contained in plasmid p205-246, contained 269 nucleotides upstream of the CP sequence and 74 nucleotides coding for the first 24 N-terminal amino acids of the CP. The second fragment, contained in plasmid p205-262, contained 364 nucleotides coding for amino acidsl2-13 lof CP and an additional 162 nucleotides downstream of the CP sequence The plasmid 283.-58 was designed by two-step PCR, in order to fuse both CP fragments from plasmids p205-246 and p205-262 in one full-length CP sequence. An upstream primer p 1.44 containing the Ncol site for cloning into plasmid pQb185, or pl.45 containing the XbaI site for cloning into plasmid pQb10, and a downstream primer p1.46 containing the HindIII restriction site were used (recognition sequence of the restriction enzyme underlined): (Sequence Removed) Two additional primers, p1.47, annealing at the 5' end of the fragment contained in p205-262, and p1.48, annealing at the 3' end of the fragment contained in plasmid p205-246 were used to amplify the fragments in the first PCR. Primers p1.47 and p1.48 are complementary to each other. (Sequence Removed) In the first two PCR reactions, two fragments were generated. The first fragment was generated with primers p1.45 and p1.48 and template p205-246. The second fragment was generated with primers pi .47 and p1.46, and template p205-262. Both fragments were used as templates for the second PCR reaction, a splice-overlap extension, with the primer combination p1.45 and pl.46 or p1.44 and p1.46 . The product of the two second-step PCR reactions were digested with XbaI or Ncol respectively, and HinclIII, and cloned with the same restriction sites into pQblO or pQb185 respectively, two pGEM-derived expression vectors under the control of E.coli tryptophan operon promoter. Two plasmids were obtained, pAP283-58 (SEQ ID NO.2) containing the gene coding for wt AP205 CP (SEQ ID NO: 1) in pQblO, and pAP281-32 (SEQ ID NO: 4) containing the nucleotide sequence of SEQ ID NO: 125 encoding for the mutein with mutation Pro5→Thr having the amino acid sequence of SEQ ID NO: 3 in pQbl85 . The coat protein sequences were verified by DNA sequencing. PAP283-58 contains 49 nucleotides upstream of the ATG codon of the CP, downstream of the Xbal site, and contains the putative original ribosomal binding site of the coat protein mRNA. EXAMPLE 2: Expression and Purification of Recombinant AP205 VLP A. Expression of recombinant AP205 VLP E.coli JM109 was transformed with plasmid pAP283-58. 5 ml of LB liquid medium with 20 ug/ml ampicillin were inoculated with a single colony, and incubated at 37 °C for 16-24 h without shaking. The prepared inoculum was diluted 1:100 in 100-300 ml of LB medium, containing 20 µg/ml ampicillin and incubated at 37 °C overnight without shaking. The resulting second inoculum was diluted 1:50 in 2TY medium, containing 0.2 % glucose and phosphate for buffering, and incubated at 37 °C overnight on a shaker. Cells were harvested by centrifugation and frozen at -80°C. B. Purification of recombinant AP205 VLP Solutions and buffers: 1. Lysis buffer 50mM Tris-HCl pH 8.0 with 5mM EDTA, 0.1% tritonXlOO and PMSF at 5 micrograms per ml. 2. SAS Saturated ammonium sulphate in water 3. Buffer NET. 20 mM Tris-HCl, pH 7.8 with 5mM EDTA and 150mM NaCl. 4. PEG 40% (w/v) polyethylenglycol 6000 in NET Lysis: Frozen cells were resuspended in lysis buffer at 2 ml/g cells. The mixture was sonicated with 22 kH five times for15 seconds, with intervals of 1min to cool the solution on ice. The lysate was then centrifuged for 20 minutes at 12 000 rpm, using a F34-6-38 rotor (Ependorf). The centrifugation steps described below were all performed using the same rotor, except otherwise stated. The supernatant was stored at 4° C, while cell debris were washed twice with lysis buffer. After centrifugation, the supernatants of the lysate and wash fractions were pooled. Ammonium-sulphate precipitation can be further used to purify AP205 VLP. In a first step, a concentration of ammonium-sulphate at which AP205 VLP does not precipitate is chosen. The resulting pellet is discarded. In the next step, an ammonium sulphate concentration at which AP205 VLP quantitatively precipitates is selected, and AP205 VLP is isolated from the pellet of this precipitation step by centrifugation (14 000 rpm, for 20 min). The obtained pellet is solubilised in NET buffer. Chromatography: The capsid protein from the pooled supernatants was loaded on a Sepharose 4B column (2.8 X 70 cm), and eluted with NET buffer, at 4 ml/hour/fraction. Fractions 28-40 were collected, and precipitated with ammonium sulphate at 60% saturation. The fractions were analyzed by SDS-PAGE and Western Blot with an antiserum specific for AP205 VLP coat protein prior to precipitation. The pellet isolated by centrifugation was resolubilized in NET buffer, and loaded on a Sepharose 2B column (2.3 X 65 cm), eluted at 3 ml/h/fraction. Fractions were analysed by SDS-PAGE, and fractions 44-50 were collected, pooled and precipitated with ammonium sulphate at 60% saturation. The pellet isolated by centrifugation was resolubilized in NET buffer, and purified on a Sepharose 6B column (2.5 X 47 cm), eluted at 3 nl/hour/fraction. The fractions were analysed by SDS-PAGE. Fractions 23-27 were collected, the salt concentration adjusted to 0.5 M, and precipitated with PEG 6000, added from a 40% stock in water and to a final concentration of 13.3%. The pellet isolated by centrifugation was resolubilized in NET buffer, and loaded on the same Sepharose 2B column as above, eluted in the same maimer. Fractions were analyzed by SDS-PAGE. Fractions 43-53 were collected, and precipitated with ammonium sulphate at a saturation of 60%. The pellet isolated by centrifugation was resolubilized in water, and the obtained protein solution was extensively dialyzed against water. About 10 mg of purified protein per gram of cells could be isolated. Purification of Aß 205 VLPs could be shown, which was analysed by SDS PAGE and Western-blotting. Fractions of recombinant AP205 VLP of the first Sepharose 4B chromatography step as well as of the last Sepharose 2B chromatography step could be shown on the silver-stained SDS-PAGE run under reducing conditions as well as by Western blotting with an anti-serum specific for AP205 VLP coat protein. Examination of the virus-like particles in Electronmicroscopy showed mat they were identical to the phage particles (FIG. 1A and 1B). FIG. 1A shows an EM picture of AP205 phage particles, while an EM picture of self assembled particles of recombinant AP205 VLP is shown in FIG. 1 B. For the sake of simplicity, the term „AP205 virus-like particle" and the term „AP205 YIP", as used within the Example Section, Tefers to a virus-like particle expressed and purified as described in Example 2 and composed of coat proteins having an amino acid sequence as set forth in SEQ ID NO: 1. EXAMPLE 3: Coupling of Derpl.2 and Flag Peptide Antigen to AP205 VLP, and Immunization of Mice with Derpl.2 Peptide Coupled to AP205 VLP A. Coupling of Derpl .2 peptide and Flag peptide to recombinant AP205 VLP The peptide Derpl.2 (sequence: CQIYPPNANKIREALAQTHSA "Der p 1 pi 17"; aa 117-137 (SEQ ID NO: 64)) and Flag (sequence: CGGDYKDDDDK (SEQ ID NO: 65)) were chemically synthesized according to art-known methods. AP205 VLP, expressed and purified as described in example 2, was resolubilized in 20 mM Hepes, 150 mM NaCl, pH 7.4 buffer (HBS buffer). Resolubilized AP205 VLP was then reacted at a concentration of 2 mg/ml (determined in a Bradford assay), with 2.85 mM SMPH (Pierce) for 30 minutes at room temperature (RT). The reaction mixture was then dialyzed against HBS buffer, and reacted with 0.714 mM Derpl 2 or FLAG, diluted in the reaction mixture from a 50 mM stock in DMSO. The coupling reaction was left to proceed for 2 hours at 15°C, and the reaction mixture dialyzed 2X2 hours against a 1000-fold volume HBS, and flash frozen in liquid nitrogen in aliquots for storage at -80°C until further use. An aliquot was thawed, and coupling of the antigen to an AP205 subunit assessed by SDS-PAGE and the protein concentration measured in a Bradford assay. The result of the coupling reaction of Derp 1.2 to AP205 VLP is shown in FIG. 2. The monomer subunit of AP205 VLP has a molecular weight of 14 kDa. Upon derivatization of AP205 VLP with the cross-linker, dimers, trimers, tetramers, pentamers and hexamers produced by cross-linking, are detected in SDS-PAGE in addition to the monomer form of the subunit FIG. 2 shows the SDS-PAGE analysis of the coupling reaction of AP205 VLP and Qp VLP to Derp 1.2 peptide. The samples were run under reducing conditions on a 16% Tris-glycine gel. Lane 1 is the protein marker, with corresponding molecular weights indicated on the left border of the gel; lane 2, derivatized QP capsid protein; lane 3, the supernatant of the coupling reaction of QP capsid protein to the Derpl.2 peptide; lane 4, the pellet of the coupling reaction of QP capsid protein to the Derpl .2 peptide; lane 5, derivatized AP205 VLP; lane 6, the supernatant of the coupling reaction of AP205 VLP to the Derpl.2 peptide; lane 7, the pellet of the coupling reaction of AP205 VLP to the Derpl.2 peptide. Coupling products corresponding to the coupling of 1,2, 3 ,4 and respectively 5 peptides per monomer are indicated by arrows in the Figure. A higher number of epitopes could be coupled to AP205 VLP than to QP capsid protein. B. Immunization of mice with Derpl .2 peptide coupled to recombinant AP205 VLP analysis of immune response and IgG subtype detennination AP205 VLP coupled to Derpl .2 peptide or Qß VLP coupled to Derpl .2 peptide were injected s.c. in mice (3 mice each) at day 0 and 14. Derpl.2 peptide was coupled to QP capsid protein using the same conditions as described under A for the coupling to AP205 VLP. Each mice was immunized with 10 µg of vaccine diluted in PBS to 200 ul. Mice were retroorbitally bled on day 20, and me titer of the antibodies specific for the Derpl .2 peptide were measured in an ELISA against Derpl .2 peptide. The Der p I peptide "Der p I p52" was coupled to bovine KNAse A using the chemical cross-linker sulfo-SPDP. ELISA plates were coated with coupled RNAse preparations at a concentration of 10 µg/ml. The plates were blocked and then incubated with serially diluted mouse sera. Bound antibodies were detected with enzymatically labeled anti-mouse IgG antibodies specific for the respective subtypes. As a control, preimmune sera of the same mice were also tested (data not shown). The results are shown in FIG. 3. FIG. 3 shows an ELISA analysis of the IgG antibodies specific for "Derp 1.2" in sera of mice immunized against the Derpl .2 peptide coupled to AP205 VLP or QP capsid protein respectively. Total IgG titers, as well as IgG subtype titers were determined. No antibodies specific for Derpl.2 could be detected in any of the preimmune sera analysed for each of the IgG subtypes. The figure shows that for both AP205 and QP, subtypes typical of a Th1 immune response are induced, as the IgG2a liter is much higher than the IgGl titer. A strong specific anti-peptide immune response was obtained with the peptide coupled to both VLPs. Antibodies specific for the carrier were also measured by ELISA, and these were comparable for both carriers. EXAMPLE 4: Modular Eukaryotic Expression System for Coupling of Antigens to VLPs This system was generated in order to add various amino acid linker sequences containing a cysteine residue to antigens for chemical coupling to VLPs. A. Construction of an EBNA-derived expression system encoding a cysteine-containing amino acid linker and cleavable Fc-Tag: pCep-Pu (Wuttke et al J. Biol. Cham. 276:36839-48 (2001)) was digested with Kpn I and Bam HI and a new multiple cloning site was introduced with the annealed oligonucleotides PH37 and PH381eading to pCep-MCS. A modular system containing a free cysteine flanked by several glycines, a protease cleavage site and the constant region of the human IgGl was generated as follows. pSec2/HygroB(InvitrogenCatNo.V910-20) was digested with Bspl20I and Hind III and ligated with the annealed oligonucleotides SU7 and SU8 leading to construct pSec-B-MCS. pSec-B-MCS was then digested with Nhe I and Hind HI and ligated with the annealed oligonucleotides PH29 and PH30 leading to construct pSec 29/30. The construct pSec-FL-EK-Fc* was generated by a three fragment ligation of the following fragments; first pSec 29/30 digested with Eco RI and Hind HI, the annealed oligonucleotides PH31 and PH32and the Bgl I/EcoRI fragment of a plasmid (pSP-Fc*-C1) containing a modified version of the human IgGl constant region (for details of the hu IgGl sequence see the sequence of the final construct pCep-Xa-Fc* (FIG. 4A-4C). The resulting construct was named pSec-FL-EK-Fc*. From this plasmid the linker region and the human IgGl Fc part was excised by Nhe I, Pme I digestion and cloned into pCep-MCS digested with Nhe I and Pme I leading to construct pCep-FL-EK-Fc*. Thus a modular vector, was created where the linker sequence and the protease cleavage site, which are located between the Nhe I and Hind HI sites, can easily be exchanged with annealed oligonucleotides. For the generation of cleavable fusion protein vectors pCep-FL-EK-Fc* was digested with Nhe I and HindHLand the Factor Xa cleavage site N-terminally flanked with amino acids GGGGCG (SEQ ID NO: 55) was introduced with the annealed oligonuclotides PH35 and PH36and the enterokinase site flanked n-terminally with GGGGCG (SEQ ID NO: 55) was introduced with the annealed oligonucleotides PH39 and PH40 leading to the constructs pCep-Xa-Fc* (FIG. 4A, nucleotide sequence as set forth in SEQ ID NO: 103, amino acid sequence as set forth in SEQ ID NO: 104) and pCep-EK-Fc* (FIG. 4B, nucleotide sequence as set forth in SEQ ID NO: 105, amino acid sequence as set forth in SEQ ID NO: 106) respectively. The construct pCep-SP-EK-Fc* (FIG. 4C,, nucleotide sequence as set forth in SEQ ID NO: 107, amino acid sequence as set forth in SEQ ID NO: 108) which in addition contains a eukaryotic signal peptide was generated by a three fragment ligation of pCep-EK-Fc* digested Kpn 1/ Bam HI, the annealed oligos PH41 and PH42 and the annealed oligos PH43 and PH44. B. Large Scale production of fusion proteins: For the large scale production of the different fusion proteins 293-EBNA cells (Invitrogen) were transfected with the different pCep expression plasmids with Lipofectamine 2000 reagent (Invitrogen Corporation; Carlsabad, CA) according to the manufacturer's recommendation. 24-36 h post transfection the cells were split at a 1 to 3 ratio under puromycin selection (lug/ml) in DMEM supplemented with 10 % FCS. The resistant cells were then expanded in selective medium. For the harvesting of the fusion proteins the resistant cell population were passed onto poly-L-lysine coated dishes. Once the cells had reached confluence, they were washed 2 times with PBS and serum free medium (DMEM) was added to the plates. The tissue culture supernatant were harvested every 2 to 4 days and replaced with fresh DMEM medium during a period of up to one month. The harvested supernatants were kept at 4 °C. C. Purification of the fusion proteins: The recombinant Fc-fusion proteins were purified by affinity chromatography using protein A sepharose CL-4B (Amersham Pharmacia Biotech AG). Briefly chromatography columns were packed with 1-3 ml protein A resin and the tissue culture supernatants containing the recombinant proteins were applied to the column with a peristaltic pump at a flow rate of 0.5 -1.5 ml/min. The column was then washed with 20-50 ml PBS. Depending on the fusion protein the protease cleavage was performed on the column or the protein was eluted as described below. Recombinant fusion proteins were eluted with a citrate/ phosphate buffer (pH 3.8) supplemented with 150 mM NaCl and the fractions containing the protein were pooled and concentrated with ultrafree centrifugal filters (Millipore Corporation; Bedford, MA). D. Protease cleavage of recombinant fusion proteins (Factor Xa, enterokinase): Eluted recombinant fusion proteins containing the enterokinase (EK) cleavage site were cleaved using the EKmax system (Invitrogen) according to the manufacturer's recommendation. The cleaved Fc part of the fusion protein was removed by incubation with protein A. The enterokinase was then removed with the EK-Away system (Invitrogen Corporation; Carlsbad, CA) according to the manufacturers recommendation. Similarly fusion proteins containing the factor Xa (Xa) cleavage site were cleaved using the restriction protease factor Xa cleavage and removal kit (Roche) according to the manufacturer's recommendation. The cleaved Fc part was removed by incubation with protein A and the protease was removed with the streptavidin resin provided with the kit The different fusion proteins were concentrated with ultrafree centrifugal filters (Millipore Corporation; Bedford, MA), quantitated by UV spectrophotometrie and used for subsequent coupling reactions. FIG. 4A-4C shows partial sequences of the different eukaryotic expression vectors used. Only the modified sequences are shown. FIG. 4A: pCep-Xa-Fc*: the sequence is shown from the Bam HI site onwards and different features are shown above the translated sequence (SEQ ID NO: 103 and SEQ ID NO: 104). The arrow indicates the cleavage site of the factor Xa protease. FIG. 4B: pCep-EK-Fc*: the sequence is shown from the Bam HI site onwards and different features are shown above the translated sequence (SEQ ID NO: 105 and SEQ ID NO: 106). The arrow indicates the cleavage site of the enterokinase. The sequence downstream of the Hind III site is identical to the one shown in FIG. 4A. FIG. 4C: pCep-3P-EK-Fc*: the sequence is shown from the beginning of the signal peptide on and different features are shown above the translated sequence (SEQ ID NO: 107 and SEQ ID NO: 108). The signal peptide sequence which is cleaved of by the signal peptidase is shown in bold The arrow indicates the cleavage site of the enterokinase. The sequence downstream of the Hind HI site is identical to the one shown in FIG. 4A. EXAMPLE 5: Eukaryotic Expression and Coupling of Mouse Resistin to AP205 VLP A. Cloning of mouse Resistin: Total RNA was isolated from 60 mg mouse adipose tissue using a Qiagen RNeasy kit according to the manufacturer's recommendation. The RNA was eluted in 40 µl H20. This total RNA was than used for the reverse transcription with an oligo dT primer using the ThermoScript™ RT-PCR System (Invitrogen Corporation; Carlsbad, CA) according to the manufacturer's recommendation. The sample was incubated at SO °C for 1h, heated to 85 °C for 5 minutes and treated for 20 minutes at 37 °C with RNAseH. 2 µl of the RT reaction were used for the PCR amplification of mouse resistin. The PCR was performed using Platinium TAQ (Invitrogen Corporation; Carlsbad, CA) according to the manufacturer's recommendation using primers PH19 and PH20. Primer PH19 corresponds to positions 58-77 and primer PH20 to positions 454-435 of the mouse Resistin sequence. The PCR mix was first denatured at 94 °C for 2 minutes and than 35 cycles were performed as follows: 30 seconds 94 °C, 30 seconds 56 °C and 1 minute 72 °C, at the end the samples were left for 10 minutes at 72 °C. The PCR fragment was purified and subcloned by TA cloning into the pGEMTeasy vector (Invitrogen Corporation; Carlsbad, CA) leading to pGEMT-mRes. In order to add appropriate restriction sites a second PCR was performed on pGEMT-mRes with the primers PH21 and PH22 primers using the same cycling program as described above. The forward primer PH21 contains a Bam HI site and nucleotides 81-102 of the mouse Resistin sequence. The reverse primer PH22 contains an Xba I site and nucleotides 426-406 of the mouse Resistin sequence. The indicated positions refer to the mouse resistin sequence Gene Accession No. AF323080.

Production, purification and cleavage of Resistin pCep-mRes-Xa-Fc* and pCep-mRes-EK-Fc* constructs were then used to transfect 293-EBNA cells for the production of recombinant proteins as described in EXAMPLE 4, section B. The tissue culture supernatants were purified as described in EXAMPLE 4, section C. The purified proteins were then cleaved as described in EXAMPLE 4, section D.

Single colonies from kanamycin and chloramphenicol-containing agar plates were expanded in liquid culture (LB medium, 30ug/ml kanamycin, 50ug/ml chloramphenicol) and incubated at 30°C with 220 rpm shaking overnight 11 of LB (with 30ug/ml kanamycin) was then inoculated 1:100 v/v with the overnight culture and grown to OD600=1 at 24°C. Expression was induced with 0.4 mM IPTG. Cells were harvested after 16 h and centrifuged at 5000 rpm. Cell pellet was suspended in lysis buffer (50 mM Tris-HCl, pH=8; 25 % sucrose; 1 mM EDTA, 1% NaN3; 10 mM DTT; 5 mM MgCl2; 1 mg/ml Lysozyme; 0.4u/ml DNAse) for 30 min. Then 2.5 volumes of buffer A (50 mM Tris-HCl, pH=8.0; 1% Triton X100; 100 mM NaCl; 0,l%NaN3; 10mMDTT;l mMPMSF) were added and incubated at 37°C for 15min. The cells were sonicated and pelleted at 9000 rpm for 15 min. The supernatant was immediately used for GST-affinity chromatography. A column GST-Trap FF of 5 ml (Amersham Pharmacia) was equilibrated in PBS, pH 7.3 (140 mM NaCl, 2.7 mM KC1,10 mM Na2HPO4,1.8 mM KH2PO4). The supernatant was loaded on the 5 ml GST-Trap FF column and subsequently the column was rinsed with 5 column volumes of PBS. The protein GST-PS-C-RANKL was eluted with 50 mM Tris-HCl, pH=8.0 containing GSH10 mM. The purified GST-PS-C-RANKL protein was digested using the protease PreScission (Amersham Pharmacia). The digestion was performed at 37°C for 1 hour using a molar ratio of 500/1 of GST-PS-C-RANKL to PreScission. Furthermore, the reaction of protease digestion was buffer exchanged-using a HiPrep 26/10 desalting column (Amersham Pharmacia), the fractions containing the proteins were pooled and immediately used for another step of GST affinity chromatography using the same conditions reported before. Purification of C-RANKL was analysed on a SDS-PAGE gel. The gel was stained with Coomassie Brilliant Blue.

The reaction solution is subsequently dialyzed twice for 2 hours against 1L of 20 mM Hepes, 150 mMNaCl, pH 7.2 at 4 °C. The dialyzed AP205 VLP reaction mixture is then reacted with the C-RANKL solution (end concentrations: 60 µM AP205 VLP, 60 uM C-RANKL) for four hours at 25 °C on a rocking shaker. Coupling products are analysed by SDS-PAGE and Western blot under reducing conditions. EXAMPLE 9 Cloning, expression and purification of XL-5 with an N-terminal amino acid linker containing a cysteine residue. Coupling to VLP and elicitalion of an immune response in mice. A. Cloning of mouse His-C-IL-5 and expression as Inclusion bodies in E. coli IL-5 was amplified from an ATCC clone (pmIL5-4G; ATCC number: 37562) by PCR using the following two primers: Spelinker3-Fl (SEQ ID NO: 90) and I15StopXho-R (SEQ ID NO: 91). The product of this PCR was used as template for a second PCR with the primers SpeNlinker3-F2 (SEQ ID NO: 92) and I15StopXho-R. The insert was digested with Spel and Notl. This insert was ligated into a pET vector derivative (pMODEC3-8 vector), previously digested with Nhe I and Not L and transformed into E.coli TGI cells. The construct generated by cloning IL5 into pMODEC3-8 comprises, from its N-terminus, a hexa-histidine tag (to facilitate purification), an Enterokinase cleavage site, a gamma 3 derived amino acid linker (flanked N-tenninally by the amino acids ALV and C-terminally by AS) containing a cysteine residue and the DNA encoding the mature form of IL-5 protein. Fidelity of the cloning procedure was confirmed by DNA sequencing. The protein released by cleavage with enterokinase is called "mouse C-IL-5-E". The construct containing IL-5 described above was termed pMODC6-IL5.2 (also referred to as pMODC6-IL5) and transformed into Kcoli strain BL21-DE3. The recombinant protein expressed in E. coli is termed His-C-IL5. Clonal BL21-DE3 cells harboring pMODC6-IL5 were grown over night in 5 ml of LB containing 1 mg/L Ampicillin. A 2.0 ml aliquot of this culture was diluted into 100 ml terrific broth (TB) containing lmg/L Ampicillin. The culture was grown to an optical density, OD600nm, of 0.7-1.0 and expression induced for 4 hours by adding 0.1 ml of a 1.0 M stock of Ispropyl ß-D-Thiogalactopyranoside (IPTG) Samples were taken every 2 hours. Recombinant His-C-IL5 was expressed in an insoluble form and located in the inclusion body fraction of induced cells. Expression of His-C-IL5 was confirmed in the following manner. A 10 ml sample of culture was taken 4 hours after induction and centrifuged for 10 min at 4000 x g. The pellet was suspended in 0.5 ml lysis buffer consisting of 50 mM Tris-HCl, 2 mM EDTA, 0.1 % triton X-100 (pH 8.0). To the suspension was added 20 ul of Lysozyme (40 mg/ml) and after 30 min at 4°C sonicated for 2 min. A 1.0 ml aliquot of benzonase and 100 ul aliquot of 50 mM MgCl2 were added and incubated for 30 min at room temperature. After centriragation for 15 min at 13000 x g the supernatant was discarded and the pellet heated for 5 min at 98°C in 100 µl of SDS loading buffer. Aliquots of 10 µl were then analyzed by SDS-PAGE under reducing conditions. SDS-PAGE analysis demonstrated a proteinband of 17 kDa corresponding to the mass of EL-5. As control, BL21-DE2 cells containing pMODC6-IL5 were grown in the absence of IPTG and extracts prepared from the insoluble cell fraction as described above. B. Purification and refolding of mouse-His-C-IL5. A larger scale expression of IL-5 from clone pMODC6-IL5 in BL21-DE3 cells was performed in order to obtain sufficient quantities of pure IL-5 for vaccine production. Overnight cultures were grown and diluted into either 100 ml or 1L volumes of TB medium containing 1.0 mg/L Ampicillin. A total of 3 liters of culture was thus prepared and grown at 37°C until OD600nm reached 0.7 at which time IPTG was added to give a final concentration of 1.0 mM. After 4 h incubation cells were harvested by centrifugation for 30 min at 10 000 x g. After harvesting the pellet was resuspended in PBS (5.0 ml/g wet weight) and centrifuged for 15 minutes at 10 000 x g. The washed pellet was stored at -20°C until further use. The bacterial pellet was suspended in PBS (2.0 ml/ g cell wet weight) using a Dounce homogenizer. Lysozyme (0.8mg/ml) was added to the suspension and incubated for 30 minutes at room temperature. The suspension was sonicated for 1 minute, 3 times on ice then benzonase and MgCl2 (10 mM final concentration) were added and incubated for 30 minutes at room temperature. TritonX-100 was added to a final concentration of 1% (w/v) the mixture gently stirred at room temperature for 30 minutes. The solution was centrifuged for 20 minutes at 20 000 x g (SS34 tubes) and the supernatant discarded. The pellet harbouring the inclusion bodies was suspended (5.0 ml/ g wet weight) in washing buffer (PBS containing 2M Urea and 1% (w/v) Triton X-l 00) using a Dounce homogenizer and agitated tor 5 minutes.The solution was centrifuged for 20 minutes at 20 000 x g and the supernatant discarded. The pellet was washed and centrifuged as above 2 more times. A final wash of the inclusion bodies was performed with washing buffer in the absence of Triton X-l 00. The His-C-IL-5 present in inclusion bodies of the pellet was solubilized in (5.0ml/g cell wet weight) denaturing buffer (100 mMNaH2PO4,10 mM Tris-HCl, 6.0 M Guanidine-hydrochloride, pH 8.0) and gently stirred for lh at 25°C. The suspension was centrifuged for 20 min. at 20 000 x g and the supernatant mixed with Ni-NTA resin (QIAgen, equilibrated with solubilization buffer). After 3 hours of gentle agitation at 4°C the slurry was poured into a glass column (C10/10) and the resin washed with 100 ml of 100 mM NaH2PO4, 10 mM Tris, 6.0 M Guanidine-hydrochloride (pH 6.3). An additional washing step was performed with 15 ml of 100 mM NaH2PO4, 10 mM Tris, 6.0 M Guanidine-hydrochloride (pH 5.9). Mouse His-C-IL5 was eluted from the resin by applying 20 ml of 100 mM NaH2PO4, 10 mM Tris, 6.0 M Guanidine-hydrochloride (pH 4.5). Purification was anylysed by SDS-PAGE. Fractions from the elution step containing His-C-IL-5 were pooled and dialysed against buffer comprising 8.0MUrea 100mMNaH2PO4,10mMTris-HCl(pH 8.0) at 4°C using a 10 kDa cut-off membrane. Following dialysis, the protein concentration was determined spectrophotometrically using the following formula; Protein (mg/ml) = (1.55 x A280nm) - (0.76 x A260nm). The concentration of the protein was diluted with dialysis buffer to 0.2 mg/ml. The solution was then dialysed with a 3.5kDa membrane for 24 hours at 4°C against refolding buffer 1 comprising 2.0 M urea, 50mM NaH2PO4,5 mM reduced Glutathione, 0.5 mM oxidized Glutathione, 0.5 M Arginine, 10% (v/v) glycerol (pH 8.5) and for a further 24h against another refolding buffer 2 comprising 50mM NaH2PO4,5 mM reduced Glutathione, 0.5 mM oxidized Glutathione, 0.5 M Arginine, 10% (v/v) glycerol, (pH 8.5). At the end the protein was dialysed for 24h at 4°C against PBS pH 8.0 then centrifuged at 10 000 x g for 30 min. The protein content of the supernatant was estimated by Bradford assay. In order to further purifiy His-C-IL5, anion exchange with Hitrap Q resin (Amersham Pharmacia, Uppsala Sweeden) was performed. His-C-IL5 was concentrated to lmg/ml using Centrifugal Filters (Ultrafree-15 Millipore, 10 kDa cutoff) and dialyzed for 14h against 50 mM Phosphate buffer pH 8.4. The solution was loaded onto a Hitrap Q column and washed with 50mM Phosphate pH 3.4 buffer. His-C-IL-5 was eluted from the column by applying aNaCl gradient from 0-1M. His-C-EL5 eluted from the column at 100 mM NaCl. Analysis of the purification was performed by SDS-P AGE and concentration measured by Bradford assay. Quartenary structure of the protein was assessed by SDS-P AGE performed under non-reducing conditions, which revealed that the His-C-IL5 is present as a dimer in the preparation. C. Vaccine production: Coupling His-C-IL5 to AP205 VLP A variety of conditions may be tested to optimize the efficiency of the coupling reaction. These include the addition of reducing agent, (TCEP) to His-C-IL5 and varying the molar ratios of AP205 VLP subunit monomer and His-C-IL5 in the coupling reaction. AP205-His-C-IL-5 vaccine is produced as follows. Purified His-C-IL-5 (40uM) is reduced for lh with an equimolar amount of TCEP in PBS pH 8.0. Reduced EL-5 (20 uM) is incubated for 4 hours at 22°C with 10 µM Qß derivatized with SMPH in atotal volume of 700 µl. The reaction is dialysed 12 hours against PBS pH 8.0 using a 300 kDa cutt-off dialysis membrane. The coupling reaction is analysed by SDS-P AGE and Western-Blot with anti-His and anti-AP205 antibodies (polyclonal rabbit antiserum). Protein concentration is measured by Bradford. The coupling efficiency [i.e. mol Qß-IL5/ mol Qß monomer (total)] is measured by densitometric analysis of the corresponding bands on the Coomassie blue stained SDS-P AGE. D. Assay of EL-5 activity The ability of the B cell lymphoma line BCL1 to proliferate in response to murine IL-5 was used to check, the bioactivity of the re-folded recombinant His-C-IL-5 (Harriman G.R. (1991) Current Protocols in Immunology 6.5.1-6.5.5 John Wiley and Sons Inc). The proliferative activity of His-C-IL5 covalently coupled to AP205 VLP may also be assessed. Recombinant murine IL-5 (R&D systems, Minneapolis USA) was used as a control. The various forms of recombinat IL-5 were incubated in flat bottom 96 well plates with 2 x 104 BCL1 cells per well and incubated for 24h at 37°C, 5% CO2.1 µCi of 3H-Thymidine (Hartmann Analytic, Switzerland) was added to each well and the plates incubated for another 6h at 37°C 5% CO2. The cells were harvested, washed and the incorporation of Thymidine determined by counting the p-emission with a liquid scintillation counter. The assay demonstrated that His-C3L5 is active. E. Immunization protocol In order to generate self reactive antibodies to mouse IL-5, four BalbC mice are injected subcutaneously a day 0 and day 14 with 25 µg of AP205-His-C-IL5 vaccine in 200 ul of PBS. To serve as a negative control, five mice are immunized at day 0 and 14 with a simple mixture of 6.4 ug AP205 VLP and 16 µg DL5 i.e. not covalently coupled (AP205 + His-C-IL-5) in PBS. Mice are bled prior to imunisation and at day 21 of the immunisation protocol. Sera are analysed by ELISA. F. Sera analysis ELISA. Maxisorp ELISA plates (Nunc) are coated with 50µl of purified His-C- IL-5 (3 µg/ml) for 14h at 4°C. The plates are washed 3 times with PBS and blocked with 2% BSA in PBS for 2h at 37°C then washed twice with PBS. Five-fold dilutions of sera are added in 2% BSA, 0.1% FCS in PBS and incubated at room temperature for 1 hour. The plates are subsequently washed 3 times with PBS and incubated with anti-mouse IgG conjugated with HRP (dilution 1:1000) at room temperature for 1h. The plates are again washed 3 times with PBS and 100 µl/well developing solution (0.066 MNa2HPO4,0.035 M citric acid, 0.032% H2O2,0.4% 1,2-Phenylenediamine dihydrochloride) is added. After 5 minutes of reaction at room temperature the ELISA is stopped with 50 ul per well 5% H2SO4. Absorbance is measured at 450 nm on a Spectramax spectrophotometer (Molecular Devices). EXAMPLE 10: Cloning, Expression and Coupling of Mouse Prion Protein A. Introduction of amino acid linker containing a cysteine residue, expression and purification of a truncated form of the mouse prion protein A truncated form (aa 121-230) of the mouse prion protein (termed mPrPt) was recombinantly expressed with a GGGGCG amino acid linker (SEQ ID NO: 55) fused at its C-terminus for coupling to AP205 VLP. The protein was fused to the N-terminus of a human Fc-fragment for purification. An enteroldnase (EK) cleavage-site was introduced behind the EK cleavage site to cleave the Fc- part of the fusion protein after purification. Construction of mPrPt-EK-Fc*. Mouse PrPt was amplified by PCR with the primer 5'PRP-.BAMHI and 3'PrP-Nhel using the plasmid pBPCMVPrP-Fc as a template. pBPCMVPrP-Fc contained the wild-type sequence of the mouse prion protein. 5'PrP-BamHI had an internal BamHi site and contained an ATG and 3'PrP-Nhel had an internal Nhel site. For the PCR reaction, 0.5 µg of each primer and 200 ng of the template DNA was used in the 50 µl reaction mixture (1 unit of PFX Platinum polymerase, 0.3 mM dNTPs and 2 mM MgSO4). The temperature cycles were as follows: 94°C for 2 minutes, followed by 5 cycles of 94°C (15 seconds), 50°C (30 seconds), 68°C (45 seconds), followed by 20 cycles of 94°C (15 seconds), 64°C (30 seconds), 68°C (45 seconds) and followed by 68°C for 10 minutes. The PCR product was digested with Bam HI and Nhel and inserted into pCEP-SP-EK-Fc* containing the GGGGCG linker sequence (SEQ BONO: 55) atthe 5'end of the EK cleavage sequence. The resulting plasmid was named pCEP-SP-mPrPrEK-Fc*. All other steps were performed by standard molecular biology protocols. Oligos: (Sequence Removed) Expression and Purification of mPrPrEK-Fc* Plasmid pCEP-SP-mPrPrEK-Fc* was transfected into 293-EBNA cells ( Invitrogen) and purified on a Protein A-sepharose column as described in EXAMPLE 4. mPrPt after cleavage has the sequence as identified in SEQ ID NO:324 with the GGGGCG linker at its C-terminus. The purified fusion protein mPrPrEK-Fc* was cleaved with enterokinase and analysed on a 16% SDS-P AGE gel under reducing conditions before and after .enterokinase cleavage. The gel was stained with Coomassie Brilliant Blue. The mPrPrEK-Fc* fusion protein could be detected as a 50 kDa band. The cleaved mPrPt protein containing the GGGGCG amino acid linker (SEQ ID NO: 55) fused to its C-terminus could be detected as a broad band between 18 and 25 kDa, The identity of mPrPt was confirmed by western blotting (data not shown). Thus, mPrPt with a C-terminal amino acid linker containing a cysteine residue, could be expressed and purified to be used for coupling to AP205 VLP. The samples loaded on the gel were the following. Lane 1: Molecular weight marker. Lane 2: mPrPrEK-Fc* before cleavage. Lane 3: mPrPt after cleavage. B. Coupling of mPrPt to AP205 VLP A solution of 120 µM AP205 VLP in 20 mM Hepes, 150 mMNaCl pH 7.2 is reacted for 30 minutes with a 25 fold molar excess of SMPH (Pierce), diluted from a stock solution in DMSO, at 25 °C on a rocking shaker. The reaction solution is subsequently dialyzed twice for 2 hours against 1L of 20 mM Hepes, 150 mM NaCl, pH 7.2 at 4 °C. The dialyzed AP205 VLP reaction mixture is then reacted with the mPrPt solution (end concentrations: 60 uM AP205 VLP, 60 uM mPrPt) for four hours at 25 °C on a rocking shaker. Coupling products are analysed by SDS-P AGE and Western blot under reducing conditions. EXAMPLE 11: Coupling of rMIF to AP205 VLP RMIF-C1 (SEQ ID NO: 114), expressed and purified as described in Example 7, in 20 mM Hepes, 150 mM NaCl pH 7.2, 0.18 mM was incubated with one molar equivalent of TCEP for 1 hour at R.T. before use in the coupling reaction. One ml of a AP205 VLP solution, 2.5 mg/ml, was reacted with a 2.3-fold molar excess of SMPH for 1 hour at R.T. The derivatized AP205 VLP was dialyzed two times 2 hours against 21 of 20 mM Hepes, 150 mM NaCl, pH 7.2.820 ul of the dialyzed derivatized AP205 VLP (0.18 mM) were subsequently reacted with 820 µl of a 0.18 mM rMF-Cl solution previously treated with TCEP as described above, for 3 hours at R.T. No precipitate was observable at the end of the coupling reaction, and the samples were analyzed by SDS-PAGE under reducing conditions, and the gel stained with Coomassie Brillant Blue. The result of the coupling reaction is shown in FIG. 6. MIF has a molecular weight of, while the AP205 VLP subunit has a molecular weight of 14 kDa while rMEF-Cl has a molecular weight of 13.

Immunization of mice with AP205 VLP coupled to rMIF-Cl AP205 VLP coupled to rMIF-Cl (from Example 11) was injected subcutaneously in female Balb/c mice (3 mice) at day 0 and 14. Each mouse was immunized with 10 µg of vaccine diluted in PBS to 200 µl. Mice were retroorbitally bled on day 21, and the titer of the antibodies specific for rMIF-Cl were measured in an ELISA specific for rMIF-Cl, as follows. ELISA plates were coated with rMEF-Cl at a concentration of 5 µg/ml. The plates were blocked and then incubated with serially diluted mouse sera. Bound antibodies were detected with enzymatically labeled anti-mouse IgG antibody. As a control, a preimmune serum of the same mice was also tested. Immunization with rMEF-Cl coupled to AP205 VLP led to a strong specific immune response against rMIF-Cl (Fig. 7), whereby the average titer of the three mice against rMEF-Cl, defined as the dilution of the serum giving half-maximal OD was of 1:31000. rMEF-Cl was therefore properly displayed on the AP205 VLP and accessible to the immune system for generation of a strong immune response. Shown on Fig. 7 is the analysis by ELISA of the IgG response specific for rMIF-Cl in the sera of mice immunised with rMIF-Cl coupled to AP205 VLP. Analysis of the day 21 -sera of the three mice (Ml, M2 and M3) was done in duplicate. Three-fold dilutions of the sera were applied to the well, "pre imm" stands for the pre immune serum of one mouse subsequently immunized with rMIF-Cl coupled to AP205 VLP. B. Immunization of rats with AP205 VLP coupled to rMIF-Cl AP205 VLP coupled to rMIF-Cl (from Example 12) is injected s.c. in rats (3 rats each) at day 0 and 28 in the absence of adjuvants. Each rat is immunized with SO µg of vaccine diluted in PBS to 200 µl. Rats are bled on day 42, and the titer of the antibodies specific for rMIF-Cl are measured in an ELISA specific for rMIF-Cl, as described above, using however an enzymatically labeled anti-Rat IgG secondary antibody. EXAMPLE 13: Coupling of the Angio I peptide to AP205 VLP and Immunization of mice A. Coupling of Angio I peptide to AP205 VLP The Angio I peptide, having the sequence of Angiotensin II (DRVYIHPF) (SEQ ID NO: 13) fused at its N-terminus to the linker sequence CGG containing a cysteine residue for coupling to the activated VLP, was chemically synthesized. AP205 VLP, expressed and purified as described in example 2, was resolubilized in 20 mM Hepes, 150 mM NaCl, pH 7.4 buffer (HBS buffer). Resolubilized AP205 VLP was then reacted at a concentration of 2 mg/ml (determined in a Bradford assay), with 1.43 mM SMPH (Pierce) for 30 minutes at room temperature (RT). The reaction mixture was then dialyzed twice against HBS buffer for 2 hours at 4°C, and reacted with 1.144 mM Angio I peptide (sequence: CGGDRVYIHPF (SEQ ID NO: 12), free amine and free acid), diluted in the reaction mixture from a 50 mM stock in DMSO. The coupling reaction was left to proceed for 2 hours at 15°C, and the reaction mixture dialyzed 2 X 2 hours against a 1000-fold volume HBS, and flash frozen in liquid nitrogen in aliquots for storage at -80°C until further use. An aliquot was thawed, and coupling of the antigen to an AP205 subunit assessed by SDS-PAGE and the protein concentration measured in a Bradford assay. Coupling efficiency of the peptide to AP205 VLP, as defined by the sum of the intensities of the bands corresponding to 1, 2 or 3 peptides coupled per monomer subunit, divided by the sum of the intensities of coupled and uncoupled AP205 monomer subunits, was of 88%. Epitope density was measured similarly as coupling efficiency, with the modification that the intensity of the coupling bands are multiplied by the number of coupled peptide per subunit in the respective band, in the numerator. Epitope density was of 1.6 Angio I peptides per AP205 VLP subunit. B. Irnmunization of mice with AP205 VLP coupled to Angio I peptide AP205 VLP coupled to Angio I peptide produced as described in part A was injected s.c. in three mice at day 0 and 14 in the absence of adjuvants. Each mouse was immunized with 25 µg of vaccine diluted in PBS to 200 µl. Mice were retro-orbbitally bled on day 21, and the titer of the antibodies specific for Angio I peptide were measured by ELISA. The Angio I peptide was coupled to bovine RNAse A using the chemical cross-linker sulfo-SPDP. ELISA plates were coated with Angio I-coupled RNAse at a concentration of 10 µg/ml. The plates were blocked and men incubated with serially diluted mouse sera. Bound antibodies were detected with enzymatically labeled anti-mouse IgG antibodies. As a control preimmune sera of the same mice were also tested. The results are shown in FIG. 8. FIG. 8 shows an ELISA analysis of the IgG antibodies specific for Angio I peptide in the sera of the three mice (1-3) immunized on day 0 and 14 against the Angio I peptide coupled to AP205 VLP. Total IgG titers were determined in the day 21 sera. No antibodies specific for Angio I could be detected in the preimmune serum analysed. A very high specific titer against Angio I of 1:69 000 in average (given as the dilution giving half maximal OD at 450 nm) was obtained, demonstrating that self-tolerance against Angio I (a self peptide in the mouse) had been broken. The data demonstrate that vaccines with very high display of peptides are obtained upon coupling antigens to AP205 VLP. The data also demonstrate that very high titers against self-antigens are obtained upon coupling of these self-antigens to AP205 VLP and subsequent immunization with the resulting vaccine in the absence of adjuvant.
