LPS treatment increases TLR-4 and PD-L1 expression in a dose-dependent manner. A549 cells were subjected to 0.5, 1, 2 µg/ml LPS for 24 h prior to western blotting. (A) Representative images of the TLR-4 and PD-L1 blots. (B) Quantification of the TLR4 and PD-L1 expression levels shown in (A). Data are shown as the mean ± SD. *P<0.05, **P<0.01 and ***P<0.001 vs. con. LPS, lipopolysaccharide; Con, control; TLR4, toll-like receptor; PD-L1, programmed-death ligand 1.
