This hypothesis proposes that age-related TREM2-dependent microglial senescence fundamentally disrupts astrocyte-microglia communication, creating a pathological cascade that drives neurodegeneration. Under normal conditions, TREM2+ microglia detect damage-associated molecular patterns and communicate threat status to astrocytes through specific cytokines (IL-33, TNF-α) and metabolites (lactate, ATP), triggering astrocytic neuroprotective programs including complement inhibition and metabolic su
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
