Peptide capable of inducing immune response to human gastric cancer and agent containing it for preventing or treating human gastric cancer

摘要

A peptide which is a fragment of a gastric cancer antigen or modification thereof, eg having the amino-acid sequence SEQ ID NO:1 or SEQ ID NO:2, when bound to an HLA molecule induces a cytotoxic T-cell response that targets a gastric cancer cell. Accordingly, this peptide is expected to be useful as an agent for preventing or treating a gastric cancer.
