Nutrient-Sensing Epigenetic Circuit Reactivation to Restore Neuronal Resilience

Aged neurons show progressive silencing of stress-response and neuroprotective genes through epigenetic mechanisms (H3K27me3 accumulation, loss of H3K27ac). The NAD+-SIRT1 axis coordinates these changes with metabolic state. Combinatorial intervention (NAD+ precursors + HDAC3 inhibitors + BRD4 modulators) may restore transcriptional resilience.
