Compositions comprising a lung tumor antigen
Compositions and methods for the therapy and diagnosis of cancer, particularly lung cancer, are disclosed. Illustrative compositions comprise one or more lung tumor polypeptides, immunogenic portions thereof, polynucleotides that encode such polypeptides, antigen presenting cell that expresses such polypeptides, and T cells that are specific for cells expressing such polypeptides. The disclosed compositions are useful, for example, in the diagnosis, prevention and/or treatment of diseases, particularly lung cancer.
1. A composition comprising a first component selected from the group consisting of physiologically acceptable carriers and immunostimulants, and a second component selected from isolated polypeptides comprising an immunogenic portion of the amino acid sequence of SEQ ID NO:809, wherein said immunogenic portion comprises at least ten contiguous amino acid residues of the amino acid sequence of SEO ID NO:809.
2. The composition of claim 1 , wherein the second component is an isolated polypeptide comprising the amino acid sequence of SEQ ID NO:809.
3. The composition of claim 1 , wherein the immunogenic portion consists of contiguous amino acid residues of SEQ ID NO:809 selected from the group consisting of: 16-35, 21-40, 26-45, 31-50, 71-90, 86-105, 91-110, 96-115, 101-120, 106-125, 111-130, 116-135, and 131-150.
4. The composition of claim 1 , wherein the second component is an isolated polypeptide consisting of the amino acid sequence of SEQ ID NO:1964.
