Over-Expression of Immunosuppressive Molecules, PD-L1 and PD-L2, in Ulcerative Colitis Patients

PD-1, PD-L1 and PD-L2 expression in mouse prostate cancer.

Programmed cell death protein 1 (PD-1) and its ligands PD-L1 and PD-L2 play critical roles in maintaining an immunosuppressive tumor microenvironment. The purpose of the present study was to assess expression of PD-1, PD-L1, and PD-L2 in mouse prostate tumors. A total of 33 mouse prostate tumors derived from Pten-null mice were examined using immunohistochemical staining for PD-1, PD-L1, and PD...

downregulation of immunosuppressive molecules, pd-1 and pd-l1 but not pd-l2, in the patients with multiple sclerosis

programmed cell death-1 (pd-1) and its ligands, pd-l1 and pd-l2, have been regarded as important immune system regulatory molecules. the aberrant expression of the molecules has been related to several autoimmune disorders. this study is aimed to assess the mrna expression level of pd-1, pd-l1, and pd-l2 molecules in the peripheral blood mononuclear mells (pbmcs) from multiple sclerosis (ms) pa...

Regulation of PD-1/PD-L1 pathway and resistance to PD-1/PD-L1 blockade

Immune checkpoint blockades, such as inhibitors against programmed death 1 (PD-1) and its ligand (PD-L1), have received extensive attention in the past decade because of their dramatic clinical outcomes in advanced malignancies. However, both primary and acquired resistance becomes one of the major obstacles, which greatly limits the long-lasting effects and wide application of PD-1/PD-L1 block...

PD-L1 and PD-L2 differ in their molecular mechanisms of interaction with PD-1.

The programmed death-1 (PD-1) molecule is involved in peripheral tolerance and in the immune escape mechanisms during chronic viral infections and cancer. PD-1 interacts with two ligands, PD-L1 and PD-L2. We have investigated the molecular mechanisms of PD-1 interactions with its ligands by surface plasmon resonance and cell surface binding as well as the ability of the two ligands to compete f...
