**Background and Rationale**
Microglia, the resident immune cells of the central nervous system, play dual roles in neurodegeneration—acting as both neuroprotective mediators and contributors to neuroinflammation. Recent research has highlighted the concept of microglial senescence, where these cells adopt a senescence-associated secretory phenotype (SASP) that perpetuates chronic inflammation and tissue damage. The Triggering Receptor Expressed on Myeloid cells 2 (TREM2) has emerged as a criti
**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
