The role of FUT8‐catalyzed core fucosylation in Alzheimer’s amyloid‐β oligomer‐induced activation of human microglia

A previous RNA‐seq study of human Alzheimer’s disease (AD) brain samples revealed significant upregulation of FUT8 coding for α1‐6 fucosyltransferase in parahippocampal gyrus, suggesting a role of FUT8 and the core fucosylation it catalyzes in early AD. Despite the well‐recognized roles of core fucosylation in immune regulation, its significance in microglial function, especially in neurodegenerative conditions such as AD, has rarely been studied.
