摘要:

阿尔茨海默病(AD)是最常见的神经退行性疾病之一,临床表现为认知和记忆功能障碍。钙蛋白酶(calpain)在细胞中广泛地被激活,钙蛋白酶的紊乱会引起AD病理学中tau蛋白过度磷酸化和tau蛋白的异常剪切。钙蛋白酶通过影响糖原合成酶激酶3和蛋白磷酸酶2A的活性,从而使tau蛋白多个位点发生异常过度磷酸化,并且介导tau蛋白单体的截断,诱导神经变性。钙蛋白酶有望成为AD药物治疗的潜在靶点。

Abstract:

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases, which is characterized by cognitive and memory dysfunction. Calpain is widely activated in cells. Disturbance of calpain is currently thought to a main cause of hyperphosphorylation and abnormal cleavage of tau protein in AD pathology. Calpain affects the activities of glycogen synthase kinase 3 and protein phosphatase 2A, which causes abnormal hyperphosphorylation of multiple sites of tau protein, and mediates truncation of tau protein monomers, and induces neurodegeneration. Calpain is expected to be a potential target for drug therapy of AD.

Key words: calpain, Alzheimer's disease, tau protein, hyperphosphorylation, cleavage, review
