A1-Reactive Astrocytes and a loss of TREM2 are associated to an early state of pathology in a mouse model of Cerebral Amyloid Angiopathy

In this study, we dissect in detail the glial and immune responses associated to early stages of CAA. To do so, RNAseq gene expression analysis were performed in a mouse model for Familial Danish Dementia (FDD), a neurodegenerative disease characterized by the accumulation of Danish amyloid (ADan) in the vasculature. Findings observed in this CAA mouse model were complemented with primary culture assays. Overall design: RNAseq of 3 replicates of WT (control) and Tg-FDD
