We also hypothesized that simultaneous blockade of the PD1/ PDL1 interaction would promote a successful antitumor response. To test this, immunocompetent C57BL/6 mice were implanted with GL261 glioma cells in the brain. Mice were then stratified into 4 treatment groups (Tx on days 3 and 13 ...

PD1, an inhibitory receptor, is found on T cells, B cells, and myeloid cells. Its primary ligand, PD-L1, is expressed on the surface of tumor cells and antigen-presenting cells (APCs) [13]. The interaction between PD1 and PD-L1 plays a critical role in maintaining immune homeostasis and...

Interaction between PD-L1 ligands on tumor cells and lymphocyte PD-1 suppresses immune response; there- fore, PD-L1 expression in tumor cells indicates that the tumor cells are capable of immune evasion [17]. There- fore, it is important to evaluate PD-1 within tumor- infiltrating lymphocytes...
