The present invention relates toproteins and peptides, and subsequences, portions or modifications thereof and methods and compounds comprising the same for eliciting, stimulating, inducing, promoting, increasing, or enhancing an anti-immune response in a subject.

Antigens and epitopes derived from

The invention relates to combinations of peptides or variants thereof derived from a portion of an amino sequence of a house dust mite allergen, e.g. the allergens Der p 1, Der f 1, Der p 2 and/or Der f 2. Such peptides comprise at least one T cell epitope and a significant high number of patients in a worldwide population will have HLA alleles with the potential to bind the peptides of the peptide combinations. The invention also relates to the use of such peptide combinations in relieving an immune response caused by a dust mite.

Peptide combinations and uses thereof in treating dust mite allergy

The present invention provides the means and methods for selecting immunogenic peptides and the immunogenic peptide compositions capable of specifically binding glycoproteins encoded by HLA alleles and inducing T cell activation in T cells restricted by the allele. One such peptide, NMLSTVLGV (SEQ ID NO: 183) is useful to elicit an immune response against influenza. The present invention also provides a heteropolymer of an isolated immunogenic peptide less than 15 amino acids in length comprising the oligopeptide NMLSTVLGV (SEQ ID NO: 183) and at least one different peptide.

HLA binding motifs and peptides and their uses

This invention uses our knowledge of the mechanisms by which antigen is recognized by T cells to identify and prepareepitopes, and to develop epitope-based vaccines directed towards malaria. More specifically, this application communicates our discovery of pharmaceutical compositions and methods of use in the prevention and treatment of malaria. In particular, this application discloses isolated peptides comprising oligopeptides, for example the oligopeptide GVSENIFLK, or isolated peptides conjugated with T helper peptides that are used as antigens in epitope-based vaccines to prevent and/or treat malaria.

[object Object]

The subject invention provides novelantigens and novel polynucleotides encoding these antigens. Also provided by the subject invention are methods of using these antigens and polynucleotides.

This invention uses our knowledge of the mechanisms by which antigen is recognized by T cells to develop epitope-based vaccines directed towards HBV. More specifically, this application communicates our discovery of pharmaceutical compositions and methods of use in the prevention and treatment of HBV infection.

Inducing cellular immune responses to hepatitis B virus using peptide compositions

This invention uses our knowledge of the mechanisms by which antigen is recognized by T cells to identify and prepare human papillomavirus (HPV) epitopes, and to develop epitope-based vaccines directed towards HPV. More specifically, this application communicates our discovery of pharmaceutical compositions and methods of use in the prevention and treatment of HPV infection.

Inducing cellular immune responses to human papillomavirus using peptide and nucleic acid compositions

A peptide comprising an amino acid sequence derived from a human papilloma virus (HPV) protein, wherein said amino acid sequence has the ability to bind to a human Major Histocompatibility Complex Class I molecule. Its use in prophylactic or therapeutic treatment of cervical carcinoma and other HPV-related diseases.

Peptides of human Papilloma virus for use in human T cell response inducing compositions

The present invention provides the means and methods for selecting immunogenic peptides and the immunogenic peptide compositions capable of specifically binding glycoproteins encoded by HLA alleles and inducing T cell activation in T cells restricted by the allele. The peptides are useful to elicit an immune response against a desired antigen. The immunogenic peptide compositions of the present invention comprise immunogenic peptides having an HLA binding motif, where the peptide is from a target antigen. Target antigens of the present invention include prostate specific antigen (PSA), hepatitis B core and surface antigens (HBVc, HBVs) hepatitis C antigens, Epstein-Barr virus antigens, melanoma antigens (e.g., MAGE-1), human immunodeficiency virus (HIV) antigens, human papilloma virus (HPV) antigens, Lassa virus,(MT), p53, CEA, trypanosome surface antigen (TSA) and Her2/neu. An example of an immunogenic peptide of the present invention corresponds to a peptide less than about 15 amino acids in length that comprises an HLA-A2.1 binding motif, where the peptide comprises the p53 sequence SMPPPGTRV.

HLA binding peptides and their uses

The present invention provides compositions and methods of inhibiting or inducing activation of T cells in a patient. The methods comprise administering a therapeutically effective dose of pharmaceutical compositions comprising a pharmaceutically acceptable carrier and peptides of between about 4 and about 20 residues, that bind antigen binding sites on MHC molecules encoded by substantially all alleles of a DR locus. These peptides are referred to as pan DR binding peptides. The pan DR binding peptides can be used to inhibit immune responses associated with immunopathologies, such as autoimmunity, allograft rejection and allergic responses. The peptides can also be used in combination with CTL peptides to enhance a CTL response.

Inducing cellular immune responses to hepatitis B virus using peptide and nucleic acid compositions

A composition or vaccine composition comprising eight isolated epitopes consisting of YLSGANLNV (SEQ. ID. NO: 1), IMIGVLVGV (SEQ. ID. NO: 2), KLBPVQLWV (SEQ. ID. NO: 3), SMPPPGTRV (SEQ. ID. NO: 4), KVAELVHFL (SEQ. ID. NO: 5), YLQLVFGIEV (SEQ. ID. NO: 6), RLLQETELV (SEQ. ID. NO: 7), and, VVLGVVFGI (SEQ. ID. NO: 8).

HLA class I A2 tumor associated antigen peptides and vaccine compositions

The complete nucleotide and amino acid sequences of the human MAGE-1 antigen are provided. Peptides from residues of the C-terminal are used to define epitopes that stimulate HLA-restricted cytotoxic T lymphocyte activity against MAGE-1 antigens. The peptides are particularly useful in methods for stimulating the immune response of individuals against MAGE-1 antigens associated with melanomas.

MAGE-1 c-terminal immunogenic peptides

The present invention is based on peptide binding specificities of HLA DR4w4, DR1 and DR7. Peptides binding to these DR molecules have a motif characterized by a large aromatic or hydrophobic residue in position 1 (Y, F, W, L, I, V, M) and a small, non charged residue in position 6 (S, T, C, A, P, V, I, L, M). In addition, allele-specific secondary effects and secondary anchors are defined, and these results were utilized to derive allele specific algorithms. By the combined use of such algorithms peptides capable of degenerate DR1, 4, 7 binding were identified.
