Fig. 3From: Role of TLR4-p38 MAPK-Hsp27 signal pathway in LPS-induced pulmonary epithelial hyperpermeabilityEffect of LPS on p38 MAPK phosphorylation. A549 cells were stimulated by LPS in (a) time- or (b) dose-dependent manner. p-p38 was detected by western blotting. n = 3, *P < 0.05 versus controlBack to article page
