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
