Abstract
A new family of tumor rejection antigen precursors, and the nucleic acid molecules which code for them, are disclosed. These tumor rejection antigen precursors are referred to as GAGE tumor rejection antigen precursors, and the nucleic acid molecules which code for them are referred to as GAGE coding molecules. Various diagnostic and therapeutic uses of the coding sequences and the tumor rejection antigens, and their precursor molecules are described. Tumor rejection antigens are also shown.
Claims4
An isolated peptide, the amino acid sequence of which consists of the amino acid sequence set forth in SEQ ID NO:
- 21, or the amino acid sequence set forth in SEQ ID NO:
- 22.
Method for determining presence of cytolytic T lymphocytes in a body fluid sample which are specific for complexes of HLA-A29 molecules and SEQ ID NO:
- 21 or 22, comprising contacting a sample of cells which present HLA-A29 on their surface with a polypeptide comprising SEQ ID NO:
- 21 or 22, under conditions favoring processing of said polypeptide to the polypeptide SEQ ID NO:
- 23 and binding of SEQ ID NO:
- 21 or 22 to said HLA-A29 molecules, contacting a body fluid sample believed to contain said cytolytic T lymphocytes to said cells presenting complexes of SEQ ID NO:
- 21 or 22 and HLA-A29 on their surface, and determining at least one of (i) tumor necrosis factor released by cytolytic T lymphocytes or (ii) lysis of said cells presenting said complexes, as a determination of presence of said cytolytic T lymphocytes in said sample.
