Positive TLR4 and PD-L1 expression are more readily observed in lung cancer tissues. (A-D) Representative images of (A) lung adenocarcinoma and (B) lung squamous cell carcinoma tissues exhibiting TLR4 staining. Representative images of (C) lung adenocarcinoma and (D) lung squamous cell carcinoma tissues exhibiting PD-L1 staining. The number of tissues staining positive for (E) TLR4 and (F) PD-L1 expression in cancer and para-cancerous tissues. Scale bar, 50 µm. #P<0.01 vs. para-cancerous tissue. TLR4, toll-like receptor; PD-L1, programmed-death ligand 1; ADC, adenocarcinoma; SCC, squamous cell carcinoma.
