To obtain hints towards the nature of the recognized antigens, we in silico subjoined TCR CDR3 sequences, which have been experimentally verified to recognize melanoma differentiation (MDA) and cancer testis antigens (CTA), i.e., gp100, MAGEA1, MART-1, or NY-ESO-1, derived peptide/MHC complexes (Fig. 5b and Suppl. Here, MAGEA1 is linked to cancer.
