Mechanism of action

PD-1 (programmed death receptor 1) is an immune checkpoint that normally suppresses T cell activity to prevent autoimmunity. Tumors exploit this mechanism by expressing PD-L1 and PD-L2 ligands, which bind PD-1 and inactivate tumor-infiltrating T cells. PD-1 inhibitors restore anti-tumor immunity by blocking this interaction, enabling cytotoxic T lymphocytes to mount an effective response against malignant cells.
