虫草素抑制脂多糖诱导的支气管上皮细胞炎症反应
Cordycepin suppresses lipopolysaccharide-induced inflammatory responsesin human bronchial epithelial cells
摘要
Abstract
Objective:To investigate the role of cordycepin in regulating the inflammatory response of human bronchial epithelial cells and its underlying mechanism.Methods:The human bronchial epithelial cells (16HBE),which grew in good condition,were treated with different concentrations of cordycepin (0,10,20,40,60 μmol/mL) for 4 hours and then treated with lipopolysaccharide(LPS,1 mg/L) for 12 hours.MTT assay was used for the detection of cell vitality.At the same time,the mRNA expression level of inflammatory cytokines (IL-8,TNF-α) was evaluated by quantitative real-time PCR.The level of p-AKT2 expression was analyzed by Western blotting analysis.Results:Cordycepin could protect bronchial epithelial cells from damage of LPS in a concentration-dependent manner(P<0.05),and attenuated LPS-induced release of pro-inflammatory cytokines(P<0.05),down-regulate the phosphorylation level of AKT2 induced by LPS(P<0.05).Conclusion:Cordycepin shows active inhibitory effect on the inflammatory response of 16HBE cells,possibly through mediating relevant signal pathway of AKT2.关键词
