WebCheckpoint inhibitor therapy is a form of cancer immunotherapy. The therapy targets immune checkpoints, key regulators of the immune system that when stimulated can dampen the immune response to an immunologic stimulus. Some cancers can protect themselves from attack by stimulating immune checkpoint targets. WebApr 13, 2024 · Immune checkpoints, which include CTLA-4, PD-1 and its ligand PD-L1, act as inhibitory regulatory molecules that brake the immune system. Nevertheless, tumor cells have the ability to express PD-L1, which binds to PD-1 on the surface of T cells, allowing them to be neglected by the immune surveillance, thus enabling the immune escape [ 19 ].
