鼠李糖乳杆菌对老年小鼠术后海马区小胶质细胞激活及Tau蛋白磷酸化的影响
目的探讨术前益生菌鼠李糖乳杆菌(LGG)灌胃对麻醉手术老年小鼠海马区小胶质细胞及Tau磷酸化的影响。方法18月龄C57BL/6J小鼠30只随机分为3组,10只/组:对照组,麻醉手术组,麻醉手术+鼠李糖乳杆菌组。生理盐水/LGG 10<sup>9</sup> CFU 150 μL灌胃,每日 1 次,连续20 d后接受异氟醚麻醉+剖腹探查手术,术后12 h免疫荧光染色检测海马区小胶质细胞激活状态,ELISA 检测IL-6的浓度变化,Western blot 检测Tau蛋白磷酸化位点Tau-pS202/pT205和total Tau蛋白表达变化。结果对照组海马区小胶质细胞呈静...
