1、 HYPERLINK https:/www.MedChemE/Targets/PD-1_PD-L1.html PD-1/PD-L1PD-1/Programmed death-ligand 1Programmed death-1 (PD-1) is a cell surface receptor that functions as a T cell checkpoint and plays a central role in regulating Tcell exhaustion. PD-1 is activated by the engagement of its ligands PDL-1

2、or PDL-2. PD-1 receptor delivers inhibitory checkpointsignals to activated T cells upon binding to its ligands PD-L1 and PD-L2 expressed on antigen-presenting cells and cancer cells,resulting in suppression of T-cell effector function and tumor immune evasion. Inhibiting the programmed cell death-1(

3、PD-1)/programmed cell death-ligand 1 (PD-L1) pathway is an attractive strategy for tumor immunotherapy.PD-1 is expressed on activated T cells, B cells, monocytes, dendritic cells (DCs), regulatory T cells (Tregs), and natural killer T cells(NKT). It is a member of a family of immunoglobulin domain (

4、Ig) co-receptors that modify the outcome of activation of the T cellreceptor by an antigen-presenting cell (APC) or infected target cell. PD-L1 is widely and constitutively expressed on bothhematopoietic and nonhematopoietic cells; e.g., naive T and B cells, vascular endothelial cells, and pancreati

5、c islet cells, whereasPD-L2 is exclusively and inducibly expressed on professional APCs.www.MedChemE 1 HYPERLINK https:/www.MedChemE/Targets/PD-1/PD-L1.html PD-1/PD-L1 HYPERLINK https:/www.MedChemE/Targets/PD-1/PD-L1.html HYPERLINK https:/www.MedChemE/Targets/PD-1/PD-L1.html Inhibitors, HYPERLINK ht
