Abstract
Graphical AbstractMicroglial phagocytosis and exocytosis of Aβ are mediated by primary cilia, which influence extracellular proteostasis, Aβ plaque formation, and neurite dystrophy. When microglia in wild-type mice develop into the disease-associated state, they require genes involved in primary ciliogenesis and extracellular vesicle secretion. Inhibition of Ift88, a key cilia gene, in microglia stimulates phagocytosis and the secretion of extracellular vesicles with an altered proteomic composition, leading to the failure of extracellular proteostasis and neurite degeneration.
