Background:. Programmed death-ligand 1 (PD-L1) expression on tumor cells (TC) or tumor-infiltrating immune cells (IC) is associated with OS, PFS and ORR in pts with advanced NSCLC treated with atezolizumab (anti-PDL1, MPDL3280A; Spigel et al, Spira et al, ASCO 2015), indicating that PD-L1 expression on both TC and IC is important for anti-tumor immunity. However, these 2 distinct expression patterns suggest the existence of previously unidentified NSCLC subtypes with distinct immunologic profiles. . By: .

Motivation of research, why they did what they did…. PD-L1 is a transmembrane protein involved in regulation of cellular and humoral immune responses. PD-L1 is mainly expressed on antigen presenting cells, activated T and B cells, placenta. PD-1 (receptor) is broadly expressed on activated lymphoid cells. It is also highly expressed on regulatory T cells, and over-expressed on exhausted T cells. Interaction of PD-L1 with receptor PD-1 helps regulate T cell activation and tolerance during pregnancy, tissue allografts, and in autoimmune disease.. M. edicine. . Marianna Nuti.
