Chronic Ethanol Exposure Sensitizes The Lung In A Mouse Model Of Endotoxemia-Induced Acute Lung Injury : Potential Role Of Plasminogen Activator Inhibitor-1., Lauren G. Poole
Electronic Theses and Dissertations
The goal of this project is to characterize a new mouse model of alcohol-enhanced acute lung injury (ALI) and to determine the role of plasminogen activator inhibitor-1 (PAI-1) in this model. Male mice (WT and PAI-1-/-) were exposed to ethanol-containing Lieber-DeCarli diet or pair-fed control diet for 6 weeks; some animals were administered intraperitoneal lipopolysaccharide (LPS) prior to sacrifice. Chronic alcohol feeding enhanced induction of the chemokines MIP-2 and KC (murine IL-8 homologues) after LPS injection in wild type animals. This enhanced chemokine expression did not correlate with enhanced pulmonary neutrophil infiltration, however animals exposed to chronic ethanol showed sustained …
