Study of Brain Immune Cells Reveals New Clues to Alzheimers Disease Progression

Researchers have mapped over 830,000 brain immune cells, revealing a protective subtype of microglia that increases with Alzheimers progression. This subtype aids in clearing harmful material via the TREM2 pathway. The findings suggest new therapeutic targets focused on bolstering the brain's immune response rather than solely targeting amyloid plaques.
