背景
Programmed cell death 1 ligand 1 (CD274/PD-L1) is a ~32 kDa protein. Plays a critical role in induction and maintenance of immune tolerance to self. As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response. Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10). CD274 is the therapeutic target of atezolizumab (Tecentriq) and durvalumab (Imfinzi).
