mRNA expression of Toll-like receptors in models after exposure to diesel exhaust particles (DEP). Fold change of TLR2 (a) and TLR4 (b) expression in PBEC-ALI and PBEC-AL/MQ (N = 6) after exposure to DEP and incubated for 24 h; Exposure: sham: clean air; DEP: 12.7 μg/cm2; Data presented as median and 25th -75th percentiles, fold change =2-ΔCt of models / 2-ΔCt of sham exposed PBEC-ALI; *: P < 0.05 VS Sham exposure
