NRR:脑缺血与阿尔茨海默病在发病机制上联系密切

2013-11-06 EurekAlert EurekAlert

阿尔茨海默症患者脑中老年斑的主要成分β淀粉样蛋白及脑缺血再灌注损伤均可导致脑组织神经细胞死亡,并致认知功能受损。最近有研究表明,脑缺血与阿尔茨海默病在发病机制上联系密切。 为此,清华大学生命科学学院宋波博士所在课题组进行了一项关于“Amyloid beta-peptide worsens cognitive impairment following cerebral ischemia-reper

阿尔茨海默症患者脑中老年斑的主要成分β淀粉样蛋白及脑缺血再灌注损伤均可导致脑组织神经细胞死亡,并致认知功能受损。最近有研究表明,脑缺血与阿尔茨海默病在发病机制上联系密切。

为此,清华大学生命科学学院宋波博士所在课题组进行了一项关于“Amyloid beta-peptide worsens cognitive impairment following cerebral ischemia-reperfusion injury”的研究,发现脑室注射β淀粉样蛋白结合脑缺血再灌注能加重大鼠学习记忆的损伤和神经细胞的死亡。

β淀粉样蛋白与脑缺血再灌注具有协同损伤作用,二者通过影响糖原合酶激酶3β和蛋白磷酸酶2A的活性而导致tau蛋白的磷酸化水平升高,从而加剧了神经细胞损伤。【原文下载

作者认为,文章结果为脑缺血再灌注后认知障碍机制的研究提供了参考依据。文章发表在《中国神经再生研究(英文版)》杂志2013年9月第26期。

中国缺血性脑卒中和短暂性脑缺血发作二级预防指南2010.pdf 由于缺血性脑卒中和TIA患者有着不同的病因、病理生理机制、血管损伤的部位及不同的危险因素,且患者的依从性不同,决定了患者脑卒中再发的风险也有所差别。因而,从二级预防的角度看,对脑卒中患者进行科学的危险分层尤为重要,比如,采用Essen脑卒中危险评分或ABCD2评分法。 此指南适用于神经内科、内科和其他相关科室的医生,目的是为临床医
