CD8A and melanoma: To determine whether the cells involved in Q702-induced TGI treatment were class I MHC molecule-restricted and epitope-specific conventional CD8 T cells, and to evaluate the change in the epitope-specific conventional CD8 T cell population induced by the combination of Q702 and anti-PD-1 antibody, we performed experiments using a syngeneic model with B16F10-ovalbumin (OVA) melanoma cells.
