摘要 目的通过建立体外氧糖剥夺模型模拟缺血缺氧环境,观察轴突导向因子netrin-1对脑微血管内皮细胞氧糖剥夺损伤后的作用。方法体外培养脑微血管内皮细胞,免疫荧光法检测其netrin-1受体结直肠癌缺失基因(deleted in colorectal cancer,DCC)及uncoordinated(UNC)5H2的表达;并使用不同浓度netrin-1作用于氧糖剥夺损伤的脑微血管内皮细胞,Cell Counting Kit-8(CCK-8)试剂盒及Annexin V-FITC/PI细胞凋亡双染试剂盒检测其细胞活性。结果脑微血管内皮细胞表达UNC5H2受体,无DCC受体表达;与对照组相比,浓度为10、50、100 ng/m L的netrin-1作用于氧糖剥夺损伤的脑微血管内皮细胞后细胞活性增强(10 ng/m L:1.25±0.20,存活率63.33%,P<0.05;50 ng/m L:1.41±0.17,存活率79.40%,P<0.05;100 ng/m L:1.33±0.27,存活率75.98%,P<0.05),且在其浓度为50 ng/m L时细胞活性最强。结论 Netrin-1对氧糖剥夺损伤的脑微血管内皮细胞具有剂量相关的保护作用,这种保护作用可能由其受体UNC5H2介导。
