Host programmed death ligand 1 is dominant over programmed death ligand 2 expression in regulating graft-versus-host disease lethality.
Programmed death 1 (PD-1) and its ligands, PD-L1 and PD-L2, play an important role in the maintenance of peripheral tolerance. We explored the role of PD-1 ligands in regulating graft-versus-host disease (GVHD). Both PD-L1 and PD-L2 expression were upregulated in the spleen, liver, colon, and ileum of GVHD mice. Whereas PD-L2 expression was limited to hematopoietic cells, hematopoietic and endo...
متن کاملClinical significance of programmed death-1 ligand-1 and programmed death-1 ligand-2 expression in human esophageal cancer.
PURPOSE The negative regulatory programmed death-1/programmed death-1 ligand (PD-1/PD-L) pathway in T-cell activation has been suggested to play an important role in tumor evasion from host immunity. In this study, we investigated the expression of PD-L1 and PD-L2 in human esophageal cancer to define their clinical significance in patients' prognosis after surgery. EXPERIMENTAL DESIGN PD-L1 a...
متن کاملCritical Role of the Programmed Death-1 (PD-1) Pathway in Regulation of Experimental Autoimmune Encephalomyelitis
Experimental autoimmune encephalomyelitis (EAE) is mediated by autoantigen-specific T cells dependent on critical costimulatory signals for their full activation and regulation. We report that the programmed death-1 (PD-1) costimulatory pathway plays a critical role in regulating peripheral tolerance in murine EAE and appears to be a major contributor to the resistance of disease induction in C...
متن کاملAntagonizing programmed death-1 and programmed death ligand-1 as a therapeutic approach for gastric cancer
Malignant tumor cells are equipped with mechanisms that can help them escape the surveillance by host immune system. Immune checkpoint molecules can transduce coinhibitory signals to immunocompetent cells and exert immunosuppressive roles in antitumor immunity. Programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1) are the two important checkpoint molecules with great potential in targ...
متن کاملMolecular pathways: next-generation immunotherapy--inhibiting programmed death-ligand 1 and programmed death-1.
The aim of T-cell-based immune therapy for cancer has been to generate durable clinical benefit for patients. Following a generation of therapies that largely showed minimal activity, substantial toxicity, and no biomarkers to identify which patients benefit from treatment, early studies are showing signs that programmed death-ligand 1 (PD-L1) and programmed death-1 (PD-1) inhibitors are highly...
