Abstract

Acute lung injury (ALI) is a respiratory failure disease and the major source of mortality in the critically ill patients. The main pathological changes involved in ALI include the excessive recruitment and activation of neutrophils by increased pro-inflammatory mediators. However, any specific therapy for ALI has not been developed. The objective of this study was to investigate protective effects of parthenolide, a sesquiterpene lactone produced in feverfew, on LPS-induced lung injury. In the present study, parthenolide treatment reduced infiltration of inflammatory cells, airway permeability and production of pro-inflammatory cytokines in LPS-induced ALI mouse model. Further, LPS-stimulated phosphorylation of NF-κB, the key regulatory transcription factor in ALI, was inhibited by parthenolide treatment in lung epithelial BEAS-2B cells and alveolar macrophage MH-S cells. These results suggest that parthenolide may provide a beneficial therapeutic strategy for ALI.
