Tumor antigen peptide derivatives

摘要

Tumor antigen peptide derivatives which comprise all or part of an amino acid sequence derived from the amino acid sequence shown in SEQ ID NO: 3 through the alteration of one to several amino acid residues, which are capable of binding to HLA-A24 antigen and thus being recognized by cytotoxic T cells; the use of these tumor antigen peptide derivatives in treating, preventing and diagnosing tumors; and remedies or preventives for tumors containing these peptide derivatives as an active ingredient.
