Description
Background
CD274(CD274 molecule), also known as PDCD1L1, PDL1, B7H1, CD274 molecule, cluster of differentiation (CD274) or B7 homolog 1 (B7-H1), Programmed cell death 1 ligand 1, is a protein that in humans is encoded by the CD274 gene. Levels of B7H1 correlated with PTEN loss in glioblastoma specimens, and tumor-specific T cells lysed human glioma targets expressing wildtype PTEN more effectively than those expressing mutant PTEN. Sequence analysis predicted that it has 290-amino acid. immunoresistance in glioma is related to loss of the tumor suppressor PTEN and is mediated in part by B7H1.Programmed death ligand 1 (PD-L1) is a 40kDa type 1 transmembrane protein that has been speculated to play a major role in suppressing the immune system during particular events such as pregnancy, tissue allografts, autoimmune disease and other disease states such as hepatitis. Using microarray analysis and flow cytometry, Barber et al.(2006) found that Pd1 was highly upregulated by functionally exhausted CD8 T cells from mice infected with a lymphocytic choriomeningitis virus (LCMV) strain causing chronic infection, but not by functional memory CD8 T cells from mice infected with an LCMV strain causing acute infection.
