Summarized by Masters of Longevity from Fight Aging!.
Geroscience-focused newsletter highlighting recent research on brain‑intrinsic immune signaling and nuanced reviews of mTOR as a complex aging regulator.
Key Takeaways
- Direct intracortical blockade of PD-L1 in an Alzheimer’s mouse model restored microglial process motility and neuronal calcium activity within seven days.
- Targeting brain-intrinsic glial PD-1/PD-L1 signaling reduced amyloid-β plaque burden and increased plaque-associated microglia in treated mice.
- MTOR functions as a context-dependent signaling hub through mTORC1 and mTORC2, so nuanced modulation rather than single-target inhibition may better support healthy aging.
