Abstract

Parkinson's Disease

In article number 2413451, Zhentao Zhang and co-workers show that microglia process α-synuclein fibrils to generate novel fibrils with enhanced toxicity, promoting the onset and progression of Parkinson's disease. α-Synuclein fibrils enter microglia through TREM2. Then they are processed by asparagine endopeptidase to produce α-synuclein 1-103 fibrils, which are more toxic than naive α-synuclein fibrils. These results show that blocking the aberrant activity of microglia halts the progression of Parkinson's disease.

小胶质细胞过程α-突触核蛋白原纤维与trem2依赖方式增强其致病性(Adv. Sci. 7/2025)
在文章编号2413451中,张振涛等人发现,小胶质细胞加工α-突触核蛋白原纤维,生成具有增强毒性的新型原纤维,促进帕金森病的发生和进展。α-突触核蛋白原纤维通过TREM2进入小胶质细胞。然后经天冬酰胺内肽酶加工生成α-突触核蛋白1-103原纤维,其毒性大于原始α-突触核蛋白原纤维。这些结果表明,阻断小胶质细胞的异常活动可以阻止帕金森病的进展。
