摘要
背景:阿尔茨海默氏病(AD)是一种慢性和进行性疾病,会在物理,心理和经济方面影响护理人员,家庭和社会。当前可用的药物只能改善认知症状,对进展无影响且不能治愈,因此识别和研究新的药物靶标很重要。有证据表明胆固醇稳态紊乱可能与AD病理有关,尤其是细胞内胆固醇和由酰基辅酶A形成的细胞质胆固醇酯的区室化:胆固醇酰基转移酶1(ACAT1)可能参与了β-淀粉样蛋白(Aβ)的调节肽,参与AD。阻断ACAT1活性可获得有益的效果,因此,有人提出ACAT1可以成为潜在的新治疗靶标。本综述讨论了胆固醇稳态在AD病理中的作用,尤其是在使用ACAT抑制剂的情况下,以及它们如何作为一种治疗方法被提出。此外,还讨论了ACAT和AD的遗传关系。 结论:尽管有来自细胞和动物研究的多条证据表明,抑制ACAT是降低脑Aβ的有效方法,但在进入下一阶段之前,在机制和关注方面仍存在信息空白。另外,药物遗传学可能对理解AD以随后提出新的治疗方法有用。但是,在该区域中仍然有很多缺少的信息。
