【摘要】:目的研究β-淀粉樣蛋白(Aβ25-35)對大鼠海馬細胞內質網鈣庫的影響。方法將40只成年清潔級雄性SD大鼠按體重隨機分為4組,分別為Aβ25-35染毒組(每測一次性注射2.5μg/μl凝聚態(tài)Aβ25-35溶液2μl)、假手術組、生理鹽水組,正常對照組(不進行任何處理),每組10只。于手術后14 d,檢測海馬細胞內游離鈣離子濃度和內質網IP3、RYR、PS mRNA的表達水平。結果與正常對照組、假手術組和生理鹽水組相比,Aβ25-35染毒組海馬細胞內質網腫脹肥大,擴張明顯,且大多內質網膜破裂,游離鈣濃度明顯增高,內質網IP3、PS mRNA的表達水平升高,RYR mRNA的表達水平降低,差異有統(tǒng)計學意義(P0.05)。結論 Aβ25-35可以通過破壞大鼠海馬細胞內質網鈣穩(wěn)態(tài)而發(fā)揮神經毒性作用。
