Abstract
Background/Aims: Endotoxemia is a life-threatening situation that signifies a key challenge in the field of intensive care medicine. Proinflammatory mediators produced by macrophages play a key role in endotoxemia. Gelsolin (GSN) is involved in the process of inflammation. Methods: IL-6 and TNF-α in the supernatant were measured with an ELISA kit. NO production was assessed by measurement of nitrite concentration with the Griess assay. si-RNA directed against GSN (si-GSN) was transfected by Lipofectamine. Results: LPS decreased the levels of GSN. Recombinant GSN inhibited the cytokines induced by LPS and rescued mice from LPS-induced death, and si-GSN increased death in the LPS-pretreated mice. Conclusion: GSN exhibited a protective role in endotoxemia.
