Pharmacological activation of TREM2 signaling to shift APOE4-associated microglia from complement-mediated synaptic engulfment toward amyloid-phagocytic phenotype. Leverages strong APOE-TREM2 protein interaction (score: 0.986) and addresses APOE4's immune enhancement paradox by redirecting microglial surveillance away from synapses.

**Background and Rationale** Triggering Receptor Expressed on Myeloid cells 2 (TREM2) represents one of the most significant genetic risk factors for late-onset Alzheimer's disease, with rare loss-of-function variants conferring up to threefold increased risk of dementia. This single-pass transmembrane receptor, exclusively expressed on microglia within the brain, has emerged as a critical regulator of microglial phenotype and function throughout the lifespan. Under physiological conditions, TR
