In this study, we utilize peptide libraries representing MA antigens, such as tyrosinase (Tyr), melanoma-associated antigen A3 (MAGE-A3), melanocyte antigen/melanoma antigen recognized by T cells 1 (Melan-A/MART-1), glycoprotein 100 (gp100), and New York esophageal squamous cell carcinoma-1 (NY-ESO-1). The gene discussed is MAGEA3; the disease is esophageal squamous cell carcinoma.
