摘要 阿尔茨海默病(Alzheimer's disease,AD)是一种以进行性认知功能障碍和行为损害为特征的中枢神经系统退行性病变,是老年期痴呆的最常见类型,严重影响着老年人的生活质量.然而,其确切病因及发病机制目前尚不清楚,且缺乏有效的治疗措施.目前多认为AD的发生由遗传因素和环境因素共同决定,前者包含了两类遗传信息:一类是DNA序列所提供的传统意义上的遗传信息;另一类则是近期研究发现的表观遗传学信息,它提供了何时、何地、以何种方式去执行DNA遗传信息的指令.表观遗传学的研究为AD发病机制及治疗的探索掀开了新的篇章.本文主要从DNA甲基化、组蛋白修饰、非编码RNA的调控3个方面就近年来国内、外AD的表观遗传学调控机制和治疗的研究进展作一简要综述.
