In the effective antitumor immune process, T cells are first activated by T cell receptor (TCR) induced antigen recognition signals, and numerous co-stimulatory and co-suppression signals regulate the intensity and quality of T cell responses. Blocking for immunological checkpoints is one of the most effective strategies to enhance T cell activation.
