Cellular network perturbations point to a new microglia‐astrocyte community accelerating Alzheimer’s disease progression

Alzheimer’s Disease (AD) is a fatal neurodegenerative disease where abnormal accumulation of amyloid‐β and tau aggregates drive neurodegeneration and leads to cognitive impairment, dementia and eventually death. Combining results from recent studies, each finding a novel AD‐associated cell state of different non‐neuronal cell types, suggests a system level change of the cellular environment of the AD brain and its potential role in disease outcome.
