Study identifies immune cells outside brain as source of Alzheimer's-like damage
Source Summary
Researchers found that immune cells accumulate at much higher levels in the brains of Alzheimer's disease patients compared to healthy individuals. These cells appear to contribute to neurodegeneration, and the study reveals they originate from outside the brain. The research clarifies how these immune cells become primed to accumulate in affected brains.
Why it matters
Understanding the origin and priming mechanism of immune cells in Alzheimer's disease could lead to new therapeutic targets for preventing or slowing neurodegeneration.
