529. 阿兹海默防御:微胶细胞的基因奥秘

from 知为谁 · host 知为谁

这份资料主要是一篇来自罗格斯大学的报道摘录,重点介绍了一项关于阿尔茨海默病防御机制的科学发现。 这篇报道详细描述了神经科学家彭江如何受到家乡邻居个人故事的启发,从而更加紧迫地进行阿尔茨海默病研究。 彭江和他的同事孟孟金在《自然神经科学》上发表了一项研究,该研究发现了一种罕见的基因突变(CSF2RB A455D),这种突变能够保护大脑的免疫细胞小胶质细胞免受疾病通常造成的损害。 研究人员观察到,带有这种突变的小胶质细胞能保持“年轻”,避免长期炎症,并更有效地清除有害蛋白质,从而为阿尔茨海默病的治疗开辟了新的治疗策略,例如移植突变小胶质细胞或进行基因治疗。 他们的工作标志着阿尔茨海默病研究的一个方向性转变,即从仅仅移除有毒蛋白质转向增强大脑自身的防御系统,以赋予大脑韧性。内容来源:https://www.rutgers.edu/news/inspired-familys-struggle-scientist-helps-uncover-defense-against-alzheimers-disease
