Abstract

ABSTRACT The important role of microglia, the brain’s resident immune cells, in Alzheimer’s disease (AD) is now well recognized, however their molecular and functional diversity and underlying mechanisms still remain controversial. To transcriptionally and functionally characterize the diversity of microglia in AD and aging, we isolated the amyloid plaque-containing (XO4 + ) and non-containing (XO4 − ) microglia from an AD mouse model. Transcriptomics analysis unveiled independent transcriptional trajectories in ageing and AD. XO4 + microglial transcriptomes linked plaque phagocytosis to altered expression of bona fide late onset AD genetic risk factors. We further revealed that the XO4 + tr..
