PPT-NSCLC with high PD-L1 expression on tumor cells or tumor-in

Intervista a Federico Cappuzzo Background Programmed deathligand 1 PDL1 expression on tumor cells TC or tumorinfiltrating immune cells IC is associated with OS PFS and ORR in pts with advanced NSCLC treated with atezolizumab antiPDL1 MPDL3280A Spigel et al Spira et al ASCO 2015 indicating that PDL1 expression on both TC and IC is important for antitumor immunity However these 2 distinct expression patterns suggest the existence of previously unidentified NSCLC subtypes with distinct immunologic profiles .

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.. recurrence or systemic metastases that develop aer treatment.

Intervista a Federico . Cappuzzo. 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. .
