中国博后一作兼通讯Nature论文:为阿尔茨海默病带来颠覆性治疗方法
生物世界· 2025-07-13 03:05
2025 年 7 月 9 日,加州大学洛杉矶分校 侯珂 博士作为第一作者兼共同通讯作者,在国际顶尖学术期刊 Nature 发表了题为: How short peptides disassemble tau fibrils in Alzheimer's disease 的研究论文。 阿尔茨海默病 (AD) ,是最常见的神经退行性疾病,以认知能力逐渐衰退为特征,其与两种蛋白在大脑中的异常聚集密切相关 —— tau 蛋白 和 β-淀粉样蛋白 (A β ) 。其中, A β 蛋白 聚集体在神经元之间形成,而 tau 蛋白的缠结主要在 神经元内部形成,相比 A β 蛋白, tau 蛋白的异常聚集 与阿尔茨海默病的认 知症状及严重程度之间的关联更强。 这些 tau 蛋白聚集体主要形成 具有成对原纤维有序核心的纤维,破坏这些纤维被认为是阿尔茨海默病的一种很有前景的治疗策略。然而,这些 tau 蛋白 纤维 极 其稳定,目前还没有能够有效降解大脑中 tau 蛋白 纤维的药物或方法。 撰文丨王聪 编辑丨王多鱼 排版丨水成文 该研究表明, D 型多肽 自组装为淀粉样蛋白纤维,通过应力释放导致阿尔茨海默病来源的 tau 蛋白纤维断裂 ...
