摘要
阿尔茨海默病(Alzheimer’s disease,AD)是引起老年性痴呆的常见神经退行性疾病,主要临床表现为学习记忆功能减退、认知功能障碍,最终导致患者死亡。β-淀粉样蛋白(beta-amyloid protein,Aβ)是目前公认的AD发病的中心环节,由淀粉样前体蛋白(amyloid precursor protein,APP)经β-位点APP剪切酶-1(β-site APP cleavage enzyme-1,BACE-1)和γ-分泌酶降解生成,BACE-1介导了APP的第1次剪切,是Aβ产生的关键酶和限速酶,故BACE-1的活性决定其剪切产物Aβ的产生。

Abstract
Alzheimer’s disease (AD) is a common neurodegenerative disease leading to dementia. Its main clinical manifestations are severe memory loss as well as cognitive and behavioral impairments, which eventually leads to death. Beta-amyloid protein (Aβ) is identified as a critical factor involved in the pathogenesis of AD. It is derived from amyloid precursor protein (APP) through the action of beta-site APP cleavage enzyme-1 (BACE-1) and γ-secretase. BACE-1 is beta-secretase 1. It mediates the first cut of APP and is the key and speed-limiting enzyme during the process of Aβ generation.
