法媒:清除“僵尸细胞”或可治痴呆症

2018-10-21 11:22:52 来源:参考消息网 责任编辑:卫嘉
奇迹mu私服辅助 更称自己是这世上最幸运的女孩,如今梦想成真,让她感受到童话故事彷彿真的存在。

核心提示:法媒称,此前有研究显示,消除衰老实验鼠身上的衰老细胞,可延长其健康寿命。但科学家说,发表在英国《自然》周刊上的新研究结果首次证明,其与阿尔茨海默病有因果关系。

参考消息网9月22日报道 法媒称,9月19日发表的一项研究报告说,消除模拟患有阿尔茨海默病的实验鼠大脑中自然产生的已经死亡但有毒的细胞,减缓了与这种疾病有关的神经细胞损伤和记忆丧失。这一研究结果可能开辟治疗痴呆症的新战线。

据法新社9月19日报道,这种不能再分裂、还会对其他健康细胞造成危害的“僵尸细胞”在体内的积累,即被称为衰老的过程,是所有哺乳动物中常见的现象。

报道称,科学家早就知道,这些衰老的细胞聚集在大脑中与老年疾病有关的区域。老年疾病包括从骨关节炎和动脉粥样硬化,到帕金森症和痴呆症等等。

报道还称,此前有研究显示,消除衰老实验鼠身上的衰老细胞,可延长其健康寿命。但科学家说,发表在英国《自然》周刊上的新研究结果首次证明,其与阿尔茨海默病有因果关系。

不过他们提醒说,该研究仍需很多年才可能产生治疗方法。

美国明尼苏达州罗切斯特梅奥诊所的泰勒·布西安领导的研究小组利用转基因实验鼠,在实验中制作出了在阿尔茨海默病患者神经细胞中形成的破坏性的、类似蛛网状的Tau蛋白缠结。
