Peptide vaccines against cancer are described herein. In particular, the present invention describes epitope peptides derived from INHBB that elicit CTLs. The present invention also provides established CTLs that specifically recognize HLA-A02 positive target cells pulsed with the peptides. Antigen-presenting cells and exosomes that present any of the peptides, as well as methods for inducing antigen-presenting cells are also provided. The present invention further provides pharmaceutical compositions containing the INHBB polypeptides or polynucleotides encoding thereof, as well as exosomes and antigen-presenting cells as active ingredients. Furthermore, the present invention provides methods for the treatment and/or prophylaxis of (i.e., prevention) cancers (tumors), and/or prevention of postoperative recurrence thereof, as well as methods for inducing CTLs, methods for inducing anti-tumor immunity, using the INHBB polypeptides, polynucleotides encoding the polypeptides, exosomes or antigen-presenting cells presenting the polypeptides, or the pharmaceutical agents of the present invention. The cancers to be targeted include, but are not limited to, cholangio cellular carcinoma, esophageal cancer, non-small cell lung cancer (NSCLC), renal carcinoma, small cell lung cancer (SCLC) and soft tissue tumor. |
