Mechanistic description

Restore oxidative metabolism in APOE4 microglia through CNS-penetrant mTOR modulators that reactivate oxidative phosphorylation while maintaining inflammatory responsiveness

Mechanism / pathway

  1. MTOR
  2. neurodegeneration

Evidence for (5)

  • TREM2 drives microglia response to amyloid-β via SYK-dependent and -independent pathways.
