摘 要:摘 要:老年性痴呆症(Alzheimer{$39}s Disease, AD)是一种慢性的、进行性的神经系统退行性疾病。主要特征为各方面智力的损伤,包括学习记忆、语言、读写、行为,以及对周围环境的识别,最终可导致死亡。它有三大病理特征:(1)主要由b淀粉样肽(β-amyloid peptide, Aβ)沉积而成的淀粉样斑;(2)由高度磷酸化的Tau蛋白组成的神经纤维缠结;(3)神经元及神经突触的丢失。在AD疾病的发病机制及治疗的对策中,Aβ和乙酰胆碱酯酶(acetylcholinesterase, AChE)都有重要的作用。近年来对Aβ和AChE在AD疾病发生发展过程中相互作用的研究有了越来越多的报道。在此,作者对Aβ和AChE的关系作一综述。

Abstract: Abstract: Alzheimer{$39}s disease (AD) is a chronic, slowly progressive neurodegenerative disorder with characteristic deterioration of intellectual capacity in various domains: learning and memory, language abilities, reading and writing, praxis, interaction with the environment, and finally lead to death. It has three pathological hallmarks, including amyloid plaques, neurofibrillary tangles and selective neuronal loss. Both Aβ and AChE have an important role in physiopathology of AD and therapic methods for AD. Recently accumulating articles reported the relation between AChE and Aβ. Thus, it is necessary to review the relation.
