🧪 Overview

TREM2 is a microglial surface receptor regulating phagocytosis and survival. Loss-of-function TREM2 variants (R47H) increase AD risk ~3-fold. Therapeutic TREM2 activation may enhance amyloid plaque clearance and modulate neuroinflammation, though stage-dependent effects complicate therapeutic application.

🧬 Mechanism

No curated mechanism pathway recorded for this hypothesis.
