Mechanism of action

PD-1 is an immune checkpoint receptor that, when engaged by its ligands (PD-L1 or PD-L2), suppresses T cell activation and allows tumors to evade immune surveillance. By blocking this interaction, the antibody releases the brakes on the immune system, enabling T cells to recognize and attack cancer cells. This mechanism is fundamental to checkpoint inhibitor immunotherapy.
