PEPTIDES OF AN ANTIGEN, CAPABLE OF RECOGNITION BY OR INDUCTION OF CYTOTOXIC T LYMPHOCYTES, AND METHOD OF THEIR IDENTIFICATION

摘要

PCT No. PCT/GB93/00711 Sec. 371 Date Dec. 5, 1994 Sec. 102(e) Date Dec. 5, 1994 PCT Filed Apr. 5, 1992 PCT Pub. No. WO93/20103 PCT Pub. Date Oct. 14, 1993A method of identifying peptides of an antigen of interest which are capable of recognition by or induction of cytotoxic T lymphocytes, comprises the steps of: ascertaining a "motif" of peptides which bind to a chosen HLA class I allele; providing peptides having this motif which are present in the known sequence of the antigen of interest; screening the peptides using an HLA assembly assay; and screening the resulting peptides for recognition by or induction of cytotoxic T lymphocytes. The above peptides have been identified by this method, and the peptides and vaccines containing them are also claimed.
