Expression of p38 MAPK in Acute Lung Injury Induced by LPS in Mice

Abstract:

Objective To investigate the expression and roles of p38 mitogen-activated protein kinase (p38 MAPK) in LPS-induced acute lung injury (ALI) in mice. Methods The ALI mice models were set up by intraperineal injection of lipopolysaccharide (LPS). The expressions of p38 MAPK in lung tissues were detected by immunohistochemistry and Western-blot. Results The positive expressions of p38 MAPK distribute mainly in infiltrative inflammatory cells, epithelial cells and endothelial cells. And the level of expression of phosphated p38 MAPK in ALI group were higher obviously than that in the control group, and it reached a peak after two hours. Conclusion p38 MAPK signaling pathway was triggered by ALI induced by endotoxin.
