MAGEA1 and melanoma: We used overlapping peptides spanning the entire alpha‐fetoprotein (AFP), glypican‐3 (GPC‐3), melanoma‐associated gene‐A1 (MAGE‐A1) and New York‐esophageal squamous cell carcinoma‐1 (NY‐ESO‐1) proteins and major‐histocompatibility‐complex‐class‐I‐tetramers specific for epitopes of MAGE‐A1 and NY‐ESO‐1 to analyze TAA‐specific CD8+ T‐cell responses in a large cohort of HCC patients.
