830K-cell brain atlas reveals protective microglia subtype in Alzheimer's
DrKavner · x · 2026-09-25
Mount Sinai researchers published in Nature Genetics the most comprehensive map yet of brain immune cells, profiling over 830,000 myeloid-origin cells from 1,607 donors.
Key findings:
- A protective, disease-associated microglia subtype expands as Alzheimer's progresses, engulfing and clearing harmful material;
- Its protective effects depend entirely on the TREM2–MITF–GPNMB signaling pathway;
- The work points to therapies that bolster the brain's natural immune defenses rather than targeting amyloid plaques alone.
