**Background and Rationale** Protein aggregation represents a central pathological hallmark across multiple neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and frontotemporal dementia (FTD). While traditional therapeutic approaches have focused on preventing aggregate formation or broadly enhancing clearance mechanisms, recent insights into the heterogeneous nature of pathological protein assemblies have revealed new opportunities for precision interven

**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
