Summary

Story summary

A Nature-published international study identifies a distinct population of protective microglia that may offer new therapeutic pathways for Alzheimer’s disease.
These microglia exhibit reduced PU.1 transcription factor expression and co-expression of CD28, limiting neuroinflammation and slowing amyloid plaque buildup.
In mouse models, enhancing this protective state reduced toxic tau spread and preserved cognitive function, demonstrating PU.1 and CD28 form a molecular link with immunotherapeutic potential.
