Comparing 2 hypotheses side-by-side
## Molecular Mechanism and Rationale The archived hypothesis centers on targeting the microglial activation cascade through selective modulation of the TREM2-DAP12-SYK signaling pathway in Alzheimer's disease. TREM2 (Triggering Receptor Expressed on Myeloid cells 2) represents a critical immunoreceptor that governs microglial responses to amyloid plaques and neuroinflammatory stimuli. The molecular mechanism involves TREM2's association with the adaptor protein DAP12 (DNAX-activation protein 12
TREM2 loss-of-function variants impair microglial survival, clustering around amyloid plaques, and phagocytic clearance, creating a non-cell-autonomous amplification loop where dysfunctional microglia accelerate tau pathology. This hypothesis has the strongest human genetic support (R47H OR ~2-4 for AD risk) and active clinical validation through AL002c Phase II trials (TRAILBLAZER-ALZ2). The mechanism is druggable via agonism antibodies, with validated biomarker (sTREM2) for patient stratificat
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
