摘要

神经炎症是阿尔茨海默病(AD)的一个主要特征。在这项研究中,对从阿尔茨海默病患者大脑中获得的单细胞RNA测序(scRNA-seq)数据进行的分析提供了证据,证明在牛磺酸病进展过程中,免疫反应从先天性向适应性转变,疾病相关小胶质细胞(DAM)和CD8+ T细胞在晚期脑病阶段变得更加频繁。

Switch of innate to adaptative immune responses in the brain of patients with Alzheimer's disease correlates with tauopathy progression.

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.
