Aβ1‐40 induces venular endothelial cell ferroptosis in cerebral amyloid angiopathy via the ATF3/xCT axis: Insights from single‐cell RNA sequencing

Abstract

Amyloid‐beta (Aβ)‐induced microvascular injury is a key pathological feature of cerebral amyloid angiopathy (CAA). Recent evidence suggests that ferroptosis is implicated in Aβ pathology; however, its cell‐type specificity and regulatory mechanisms within the cerebral microvasculature in CAA remain unclear.
