氟西汀对体外培养星形胶质细胞活性及脂多糖诱导的肿瘤坏死因子-α释放的影响
Chinese Journal of Behavioral Medicine and Brain Science(2012)
Abstract
目的 通过体外培养星形胶质细胞,观察氟西汀对星形胶质细胞的活性及对脂多糖(LPS)诱导星形胶质细胞释放肿瘤坏死因子-α( TNF-α)的影响.方法 体外分离、纯化大鼠星形胶质细胞.星形胶质细胞接种到96孔板中,以浓度为(5,10,20,40)μM的氟西汀孵育24h,用甲基噻唑基四唑(MTT)法检测星形胶质细胞增殖活性;星形胶质细胞接种至48孔板,经(5,10,20,40) μM氟西汀预处理后再用1μg/ml LPS刺激,酶联免疫吸附(Elisa)法检测各组上清TNF-α的水平.结果 氟西汀浓度为20 μM,40μM时星形胶质细胞的增殖活性(OD值:0.23±0.014,0.24 ±0.012)与对照组(OD值:0.20±0.017)相比明显增加(P<0.05),经LPS刺激24h星形胶质细胞释放TNF-α水平(53.84±24.84) pg/ml与对照组(8.00±10.87) pg/ml相比明显增加(P<0.01),氟西汀浓度为10μM明显抑制LPS刺激星形胶质细胞释放TNF-α(28.85±3.36) pg/ml(P<0.05).结论 氟西汀在一定浓度范围内可促进星形胶质细胞的增殖活性,氟西汀浓度为10μM时可抑制LPS诱导的星形胶质细胞对TNF-α的释放.
