APOE4 reduction in vascular-associated fibroblasts decreases cerebral amyloid angiopathy and associated vascular dysfunction

Vascular-associated fibroblasts are a major source of pathogenic APOE4 that drives vascular dysfunction in cerebral amyloid angiopathy and are establish VAF-derived APOE4 as a compartment-specific driver of CAA and cerebrovascular dysfunction.

Priming of CD8+ T cells by peripheral dendritic cells exacerbates tau-mediated neurodegeneration.

Alzheimer's disease and primary tauopathies are marked by changes in adaptive immunity, with increased brain CD8+ T cells correlating with tau pathology severity. However, how peripheral T cells get primed to enter the brain and contribute to tau-mediated neurodegeneration remains unclear. In different disease conditio...

The sphingosine-1-phosphate receptor functional antagonist fingolimod exacerbates neuroinflammation and tau pathology in a mouse model of tauopathy

Objective T cells are increased in the brain in Alzheimer’s disease (AD) and primary tauopathies where they correlate with tau pathology. In mouse models, T cells exacerbate tau-related neuroinflammation and neurodegeneration, and depletion of T cells is neuroprotective. Here, we investigate whether the multiple sclero...
