5. our findings suggest a regulatory mechanism of PD-L1 through data analysis, in vitro and vivo experiments, which is an important factor of immune evasion in GC cells, and CXCL9/10/11-CXCR3 could regulate PD-L1 expression through STAT and PI3K-Akt signaling pathways in GC cells. PMID: 29690901
6. CD163(+)CD204(+) Tumor-associated macrophages possibly play a key role in the invasion and metastasis of oral squamous cell carcinoma by T-cell regulation via IL-10 and PD-L1 production. PMID: 28496107

23. we found that in advanced stage NSCLC patients who received nivolumab, the C allele of PD-L1 rs4143815 and the G allele of rs2282055 were significantly associated with better ORR and PFS. This is the first report that PD-L1 SNP, which was thought to increase PD-L1 expression, is associated with a response to nivolumab. PMID: 28332580
24. PD-L1 expression differs between the two components of lung ASCs. Given the complexity of lung ASCs, their treatment outcomes may be improved by administration of both EGFR TKIs and anti-PD-1/PD-L1 antibodies in cases where EGFR mutations are present and PD-L1 is overexpressed. PMID: 28387300
25. IDO and B7-H1 expressions were observed in patients with pancreatic carcinoma tissues and are important markers for PC malignant progression PMID: 30029936
26. There was higher programmed cell death protein ligand-1(PD-L1) expression in post-treatment EBV DNA-positive patients. Post-treatment positive EBV DNA status maybe a useful biomarker of worse outcomes in early stage -stage extranodal natural killer/T cell lymphoma. PMID: 30116872
27. PD-L1 is a critical TTP-regulated factor that contributes to inhibiting antitumor immunity. PMID: 29936792
28. Structural and functional analyses unexpectedly reveal an N-terminal loop outside the IgV domain of PD-1. This loop is not involved in recognition of PD-L1 but dominates binding to nivolumab, whereas N-glycosylation is not involved in binding at all. PMID: 28165004
29. While mutational analysis appeared similar to that of older patients with OCSCC who lack a smoking history, a comparatively high degree of PD-L1 expression and PD-1/L1 concordance (P=0.001) was found among young female OCSCC patients. PMID: 28969885

31. PD-L1 expression was augmented on CD8+ T cells in BALF of a patient with smoldering adult T-cell lymphoma and Pneumocystis jiroveci pneumonia. This suggested that the PD-1-PD-L1 system may suppress not only antitumor immunity but also host defense against pathogens and thereby allow establishment of chronic HTLV-1 infection and immunodeficiency.

32. MUC1 drives PD-L1 expression in triple-negative breast cancer cells. PMID: 29263152
33. Positive PD-L1 expression was found in 36.8% of inflammatory breast carcinoma (IBC) samples but was not significantly associated with the clinicopathologic variables examined. Worse overall survival (OS) was significantly associated with positive PD-L1, negative estrogen receptor, and triple-negative status. The 5-year OS rate was 36.4% for patients with PD-L1-positive IBC and 47.3% for those with PD-L1-negative. PMID: 29425258

47. Authors assessed PD-L1 expression in both tumor cells and tumor-infiltrating immune cells in the tumor specimens (complete histological sections, not tissue microarray). PMID: 28420659
48. We conclude that a subgroup of advanced disease ovarian cancer patients with high grade tumors, expressing PD-L1, may be prime candidates for immunotherapy targeting PD-1 signaling PMID: 29843813
49. PD-L1 expression is a prognostic factor related with poor survival among patients that developed non-small cell lung cancer. PMID: 29614306
50. The inhibition of PTEN also reduced the cancer effects of CD4+ T cells on non-small cell lung cancer (NSCLC) cell lines following miR-142-5p downregulation. Therefore, our study demonstrated that miR-142-5p regulated CD4+ T cells in human NSCLC through PD-L1 expression via the PTEN pathway. PMID: 29767245
