摘要 目的观察缺氧后丙泊酚对体外培养海马神经细胞谷氨酸转运蛋白(EAAT2)表达及谷氨酸摄取功能的影响。方法取10个月龄SD大鼠海马区神经细胞进行培养,制备缺氧模型后随机分为对照组和丙泊酚组。采用用Western blot及Northern blot分别测定缺氧后EAAT2蛋白和基因表达;NF-κB正义寡核苷酸和反义寡核苷酸转染各组培养细胞后,行NF-κB和EAAT2蛋白测定;同位素标记法测定谷氨酸摄取量。结果与对照组相比,丙泊酚处理后海马细胞EAAT2蛋白及mRNA均增加。NF-κB正义寡核苷酸转染培养细胞后,丙泊酚处理可明显抑制细胞核内NF-κB的表达,并上调EAAT2的表达,提高谷氨酸摄取率。结论缺氧后丙泊酚处理可通过NF-κB通路上调海马细胞EAAT2的表达,提高谷氨酸摄取率,降低兴奋性神经毒性损伤。
