Beyond 12 months human equivalent, conventional approaches fail due to irreversible epigenetic changes (DNA methylation of P2ry12 promoter, H3K27ac accumulation at disease-specific enhancers). Partial Yamanaka factor reprogramming could reset the epigenetic clock but carries oncogenic risk requiring careful titration.
**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
