Abstract:

Acute lung injury (ALI) is a common severe clinical syndrome in intensive care unit. Inflammation has been reported to play a critical role in the development of ALI. Cordycepin, an active component isolated from Cordyceps militaris, has been reported to have anti-inflammatory effects. However, the anti-inflammatory effects of cordycepin on LPS-induced ALI remain unclear. Therefore, in the present study, we assessed whether cordycepin could attenuate ALI induced by LPS. The mice were conditioned with cordycepin 1h before intranasal instillation of LPS. Lung wet/dry (W/D) ratio, MPO activity, MDA content, and inflammatory cytokines production were detected. The expression of NF-κB p65, I-κB, Nrf2, and HO-1 were detected by western blot analysis. We found that LPS significantly increased lung wet/dry (W/D) ratio, MPO activity, MDA content, and inflammatory cytokines production. However, the increases were significantly inhibited by treatment of cordycepin. LPS-induced NF-κB activation was also suppressed by cordycepin. In addition, cordycepin was found to up-regulate the expression of Nrf2 and HO-1 in a dose-dependent manner. In conclusion, our results demonstrated that cordycepin could attenuate LPS-induced ALI effectively, probably due to inhibition of inflammation and oxidative stress.
