Border-Associated Macrophage Migrasomes in Alzheimer’s Disease: An Emerging Aβ–Senescence–Microglia Axis?
Alzheimer’s disease (AD) involves not only the neural parenchyma but also brain-border interfaces in which border-associated macrophages (BAMs) regulate amyloid-β (Aβ) handling, vascular function, and immune surveillance. This review focuses on a pathological axis in which persistent vascular Aβ40 and aging-related str...
