  27. PD-L1 expression in melanoma tumor cells is lower than NSCLC or renal cell carcinoma cells. The higher response rate in melanoma patients treated with PD-1 inhibitors is likely related to PD-L1 in tumor-associated inflammatory cells. Further studies are warranted to validate the predictive role of inflammatory cell PD-L1 expression in melanoma and determine its biological significance PMID: 28223273
  28. Higher PRE PD-1(+) T cells in responders suggest active suppression of an engaged immune system that is disinhibited by anti-PD-1 therapies.

PMID: 28073845
  39. Results identified an overall low expression of PD-1 and PD-L1 in high-risk prostate cancer tissue. PMID: 28461179
  40. The biopsy tumor key protein measurements demonstrate substantial between-tumor variation in expression ratios of these proteins and suggest that programmed cell death 1 ligand 2 PD-L2 is present in some tumors at levels sufficient to contribute to programmed cell death-1 PD-1-dependent T-cell regulation and possibly to affect responses to PD-1- and programmed cell death 1 ligand 1 PD-L1-blocking drugs. PMID: 28546465
  41. Early phase clinical trials using PD-1 or PD-L1 inhibitors alone or in combination have shown objective tumor responses and durable long-term disease control, in heavily pre-treated patients, notably in the TN subtype.

  48. the positive rate of PD-L2 did not show any differences between primary tumors and metastatic lymph nodes. In multivariate analysis, PD-L1 expression, PD-L2 expression, a low density of CD8(+) T cells in primary tumors, and PD-1 expression on CD8(+) T cells in primary tumors were associated with poor prognosis. PMID: 28754154
