Abstract
The invention relates to the identification of complexes of human leukocyte antigen molecules and tyrosinase derived peptides on the surfaces of abnormal cells. The therapeutic and diagnostic ramifications of this observation are the subject of the invention.
Claims3
A method for identifying a subject for treatment with a therapeutic agent which is specific for complexes of an HLA molecule and a tyrosinase derived peptide consisting of the amino acid sequence of SEQ ID NO:
- 4, wherein said complexes are present on surfaces of abnormal cells of said subject, comprising:
- (i) contacting a sample containing abnormal cells, which has been taken from said subject, with a cytolytic T cell specific of said complexes,
- (ii) determining lysis of at least some of said abnormal cells as an indication that the subject is a candidate for said treatment.
Isolated cytolytic T cell specific for a complex of HLA-A2 and the tyrosinase derived peptide consisting of the amino acid sequence of SEQ ID NO:
- 4.
A method for identifying abnormal cells which present complexes of an HLA molecule and a tyrosinase derived peptide consisting of the amino acid of SEQ ID NO:
- 4 on their surfaces, comprising contacting a sample which contains said abnormal cells with a cytolytic T cell specific for said complexes and determining lysis of said abnormal cells by said cytolytic T cells as a determination of said abnormal cells.
