Telomere shortening in proliferative microglial niches activates p53-p21 and p16-RB pathways, causing cell cycle arrest and senescence. Cumulative nuclear DNA damage from oxidative stress activates ATM/ATR-Chk1/Chk2-p53 independently of telomeres.
**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
