Abstract

Neuroinflammation is a key feature of Alzheimer's disease (AD). In this work, analysis of single- cell RNA-sequencing (scRNA-seq) data obtained from the brain of patients with AD provides evidence supporting a switch from an innate to an adaptative immune response during tauopathy progression, with both disease-associated microglia (DAM) and CD8+ T cells becoming more frequent at advanced Braak stages.

摘要

神经炎症是阿尔茨海默病(AD)的一个关键特征。在这项研究中,对从AD患者大脑中获取的单细胞RNA测序(scRNA-seq)数据的分析提供了证据,支持在tau蛋白病进展过程中从先天性免疫反应向适应性免疫反应的转变,在Braak晚期阶段,疾病相关小胶质细胞(DAM)和CD8 + T细胞均变得更加常见。
