SIRT1-Mediated Reversal of TREM2-Dependent Microglial Senescence

h-var-b7de826706

## Mechanistic Overview SIRT1 (Sirtuin 1), a class III NAD+-dependent histone deacetylase, functions as a master metabolic sensor that couples cellular energy status to transcriptional programs governing longevity and stress resistance. In healthy microglia, SIRT1 maintains cellular homeostasis through deacetylation of key transcriptional regulators including PGC1α, p53, and FOXO transcription fa
