Study Reveals Aging Human Brains Replace Resident Immune Cells with Blood-Derived Cells Starting at Age 50

Researchers have overturned longstanding scientific dogma by discovering that beginning around age 50, the brain's memory center loses its longtime resident immune cells (microglia) and replaces them with more inflammatory immune cells derived from peripheral blood stem cells. This previously unrecognized migration may help explain how normal aging sets the stage for Alzheimer's disease and dementia.

Scientists Discover Immune Cell Migration from Blood to Brain Beginning at Age 50

Researchers have overturned long-held scientific understanding by discovering that aging human brains undergo a massive influx of peripheral blood-derived immune cells starting around age 50, replacing resident microglia with more inflammatory cells. This shift may help explain how normal aging sets the stage for Alzheimer's disease and dementia.
