Additional end points were progression-free survival, overall survival, and PD-L1 tumor proportion score (TPS) assessed by immunohistochemistry based on PD-L1 copy number status.  J, Reckamp Gly124 Cleft ( L Tyr123-Accommodating Cavity) and CC′ Loop Rearrangement Are Induced by…, Figure 4.  SM, Lesokhin A 2-tailed P < .05 was considered statistically significant.  T, Okano  V, Small-Molecule Inhibitors of the Programmed Cell Death-1/Programmed Death-Ligand 1 (PD-1/PD-L1) Interaction via Transiently Induced Protein States and Dimerization of PD-L1. Targeting the PD-1/PD-L1 immunologic checkpoint with monoclonal antibodies has recently provided breakthrough progress in the treatment of melanoma, non-small cell lung cancer, and other types of cancer.  Prevalence of PDL1 amplification and preliminary response to immune checkpoint blockade in solid tumors. , Keenan This could be partially explained by the finding that group-level and chromosome-level somatic copy number alterations are more negatively associated with cytotoxic immune cell infiltration than the other type of tumor aneuploidy, focal somatic copy number alterations, through a putative mechanism of general gene dosage imbalance rather than the action of specific genes.39 Our definitions of amplification and polysomy are more likely to represent focal and group-level or chromosome-level CNGs, respectively. (A) Front-side view. PD-L1 is expressed not only on APC, DCs, as well as on activated monocytes and B cells, but also on nonlymphoid …  Clinical significance of PD-L1 and PD-L2 copy number gains in non–small cell lung cancer. , Ikeda Second, actual PD-L1 status during nivolumab treatment might not be represented because of the interval between sampling and nivolumab therapy initiation. グナルの亢進/抑制に働く CD28/CTLA-4 ファミリーに属する、50~55 kDa のI型膜たんぱく質です。.  PD-L1 and PD-L2 genetic alterations define classical Hodgkin lymphoma and predict outcome. , Barrett These results justify the clinical application of PD-L1 FISH, considering the strong association of PD-L1 amplification with response to PD-1/PD-L1 blockade.
