SIRT1 activators enhance FOXO3 deacetylation, enhancing its DNA binding affinity and nuclear translocation to maintain heterochromatin architecture in aging neurons exposed to oxidative stress. Under oxidative stress, FOXO3 nuclear translocation protects neurons by facilitating DNA damage repair and chromatin compaction. SIRT1 deacetylates FOXO3, potentiating this neuroprotective response; however, SIRT1 declines in aged neurons, contributing to loss of heterochromatin integrity and increased ne
**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
