Cytotoxic T-lymphocyte-inducing immunogens for prevention, treatment, and diagnosis of cancer
The present invention relates to compositions and methods for the prevention, treatment, and diagnosis of cancer, especially carcinomas, such as ovarian carcinoma. The invention discloses peptides, polypeptides, and polynucleotides that can be used to stimulate a CTL response against cancer.
1. A method for eliciting a CTL response against tumor cells presenting at least one of the following epitopic peptides: SEQ ID NO: 1516, 1517, 1519, 1521, 1527, 1528, or 1529 in a subject, comprising administering to said subject a composition comprising at least one polypeptide comprising an epitopic peptide comprising an amino acid sequence selected from the group consisting of SEQ ID NO: 1516, 1517, 1519, 1521, 1527, 1528, and 1529 in an amount sufficient to induce a CTL response to said tumor cells.
2. The method of claim 1 , wherein said composition further comprises an adjuvant.
3. The method of claim 2 , wherein said adjuvant is selected from the group consisting of complete Freund's adjuvant, incomplete Freund's adjuvant, Montanide ISA-51, LAG-3, aluminum phosphate, aluminum hydroxide, alum, and saponin.
4. The method of claim 1 , wherein said composition further comprises a cytokine.
5. The method of claim 4 , wherein said cytokine is GM-CSF.
6. The method of claim 1 , wherein said composition further comprises a vehicle.
7. The method of claim 6 , where said vehicle is selected from the group consisting of a liposome, an immunostimulating complex (ISCOM), and slow-releasing particles.
8. The method of claim 7 , wherein said liposome comprises an emulsion, a foam, a micelle, an insoluble monolayer, a liquid crystal, a phospholipid dispersion, or a lamellar layer.
9. The method of claim 1 , wherein said polypeptide consists of an amino acid sequence selected from the group consisting of SEQ ID NO: 1516, 1517, 1519, 1521, 1527, 1528, and 1529.
10. The method of claim 1 wherein said tumor cells are part of a carcinoma.
11. The method of claim 1 wherein said tumor cells are part of an ovarian carcinoma.
12. The method of claim 1 wherein said polypeptide comprises at least two epitopic peptides.
13. The method of claim 12 wherein said polypeptide comprises at least three epitopic peptides.
14. The method of claim 12 , wherein said polypeptide comprises a first epitopic peptide and a second epitopic peptide, wherein said first epitopic peptide comprises an amino acid sequence selected from the group consisting of SEQ ID NO: 1516, 1517, 1519, 1521, 1527, 1528, and 1529 and said second epitopic peptide comprises an amino acid sequence selected from the group consisting of SEQ ID NO: 1516, 1517, 1519, 1521, 1527, 1528, and 1529.
