Some Brains Stay Sharp Thanks to a Plaque Eating Immune Cell That Fights Alzheimer’s

UCSF researchers have pinpointed a crucial brain receptor that helps immune cells called microglia clear out toxic amyloid beta plaques linked to Alzheimer’s disease. When microglia have plenty of this receptor, they efficiently “eat” the plaques, keeping symptoms mild. But without it, plaques accumulate quickly, leading to severe memory loss and brain damage. Microglia’s Surprising […]
