TREM2 loss-of-function variants drive Alzheimer's disease pathogenesis through a two-stage mechanism where age-related microglial senescence fundamentally disrupts astrocyte-microglia communication networks. In the first stage, TREM2-deficient microglia undergo accelerated senescence characterized by shortened telomeres, increased DNA damage, and metabolic dysfunction. This senescence transition is driven by impaired TREM2/TYROBP signaling that normally maintains microglial homeostasis and stres
