The Effect of CHIP on PS1 Stability

Abstract

阿尔茨海默氏病(Alzheimerdisease,AD)是一种以渐进性记忆力丧失和认知障碍为主要症状的神经退行性疾病,在AD病人有两个主要的病理特征:神经纤维缠结和淀粉样沉积斑。淀粉样沉积斑主要由淀粉样蛋白(Aβ)组成的。目前,Aβ级联假说是流行的AD发病机理,而Aβ是由β分泌酶和γ分泌酶顺序切割产生的,Presenilin1(PS1)又是γ分泌酶复合体的主要组成和活化中心,所以对于PS1的功能研究对阐述AD的发病机制有着重要意义。 我们实验室已经用酵母双杂交和免疫共沉淀方法确定CHIP(carboxylterminusofHsc70-interactingprotein)通过其TPR结构域...Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and progressive memory loss. AD has two pathological hallmarks in the brain: neurofibrillary tangle (NFT) and senile plaque (SP). Senile plaques are composed of β-amyloid (Aβ) peptide,which is derived from its precursor protein APP through sequential cleavages by β- and γ-secretases. γ-secretase...学位:理学硕士院系专业:生命科学学院生物学系_细胞生物学学号:2172006115220
