🧪 Overview

TREM2 signaling shapes plaque-associated microglial responses, lipid handling, APOE-related state transitions, and plaque compaction in AD. The hypothesis remains biologically strong but should be repositioned after failed standalone agonist results toward genotype- and stage-stratified intervention, likely in combination with amyloid or tau therapies.

🧬 Mechanism

No curated mechanism pathway recorded for this hypothesis.

⚖️ Evidence

⚖️ Evidence Matrix3 supports2 contradicts
Supports
The TREM2 R47H variant substantially increases AD risk, anchoring the pathway in human genetics.
Supports
TREM2 knockout impairs microglial clustering around amyloid plaques in mouse models.
Supports
TREM2 signaling is linked to lipid-droplet and lipid-metabolism programs in microglia.
Contradicts
TREM2 activation may improve target-engagement or plaque-associated phenotypes without improving cognition or neurodegeneration, and effects may depend on disease stage, APOE genotype, sex, and tau burden.
Contradicts
Lipid-laden microglia are not uniformly protective and can show dysfunctional, inflammatory, or senescent phenotypes.
