【摘要】:目的研究β-淀粉样蛋白(Aβ25-35)对大鼠海马细胞内质网钙库的影响。方法将40只成年清洁级雄性SD大鼠按体重随机分为4组,分别为Aβ25-35染毒组(每测一次性注射2.5μg/μl凝聚态Aβ25-35溶液2μl)、假手术组、生理盐水组,正常对照组(不进行任何处理),每组10只。于手术后14 d,检测海马细胞内游离钙离子浓度和内质网IP3、RYR、PS mRNA的表达水平。结果与正常对照组、假手术组和生理盐水组相比,Aβ25-35染毒组海马细胞内质网肿胀肥大,扩张明显,且大多内质网膜破裂,游离钙浓度明显增高,内质网IP3、PS mRNA的表达水平升高,RYR mRNA的表达水平降低,差异有统计学意义(P0.05)。结论 Aβ25-35可以通过破坏大鼠海马细胞内质网钙稳态而发挥神经毒性作用。
