As ID8 cancercells express the mesothelin, a well-known tumor antigen [29,30], we harvested splenocytes from treated mice, and cultured them in thepresence of 10 μg/mL of H-2Db-restricted mesothelin-derived epitope peptide(MESO406–414) or control GP33–41 epitope peptide for 3 days and assayedIFN-γ secretion in culture supernatants by ELISA. Here, MSLN is linked to neoplasm.
