OPTN deficiency leads to tau pathology and creates a 'find-me' signal attracting microglia. TREM2-activating antibodies could shift microglia from a complement-producing phagocytic state to a neuroprotective phenotype, reducing synapse loss secondary to OPTN dysfunction.

**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
