摘要

目的 探讨Ski对激活星形胶质细胞炎症因子分泌的影响。方法 从3日龄Sprague-Dawley大鼠大脑皮质分离星形胶质细胞,分为空白对照组、阴性对照组、siRNA组,siRNA组沉默Ski基因。48 h后,采用Western blotting和免疫荧光染色检测Ski表达;再以脂多糖激活星形胶质细胞24 h。ELISA检测各组细胞中肿瘤坏死因子-α (TNF-α)和白细胞介素-1β (IL-1β)的浓度。结果 siRNA组Ski蛋白表达显著降低(P<0.001);激活后,TNF-α、IL-1β浓度显著减少(P<0.001)。结论 Ski可能参与星形胶质细胞炎症反应。

Abstract

Objective To investigate the effect of Ski on the secretion of inflammatory cytokines from activated astrocytes. Methods Astrocytes were obtained from cerebral cortex of a three-day old Sprague-Dawley rat and cultured in vitro. They were divided into blank group, control group and siRNA group. The Ski gene was silenced in siRNA group. The expression of Ski was tested with Western blotting and immunofluorescence 48 hours later. Then the astrocytes were stimulated with lipopolysaccharide for 24 hours. The secretion of tumor necrosis factor α (TNF-α) and interleukin-1β (IL-1β) in activated astrocytes was detected with ELISA. Results The expression of Ski protein reduced in the siRNA group (P<0.001), as well as the secretion of TNF-α and IL-1β (P<0.001). Conclusion Ski may play a role in inflammatory response of astrocyte.
