Abstract
目的: 探讨异丙酚对星形胶质细胞氧糖剥夺/复糖复氧损伤的影响。 方法: 利用新生24 h内的BALB/c鼠婴,取脑皮层星形胶质细胞原代培养后,氧糖剥夺2 h,复糖复氧24 h;CCK8检测星形胶质细胞细胞活力;免疫印迹法(Western blot)检测自噬相关蛋白的表达。 结果: 与对照组相比,氧糖剥夺损伤时细胞活力下降,随着异丙酚浓度的升高,异丙酚可增加氧糖剥夺细胞损伤活力;氧糖剥夺损伤时自噬相关蛋白Beclin1表达和LC3-Ⅱ/LC3-Ⅰ比值增加,随着异丙酚浓度的提升,Beclin1表达和LC3-Ⅱ/LC3-Ⅰ比值减少。 结论: 异丙酚能够减轻星形胶质细胞氧糖剥夺损伤引起的过度自噬,从而减轻星形胶质细胞氧糖剥夺损伤。.
