**Molecular Mechanism and Rationale**
The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling pathway represents a critical regulatory nexus in microglial function, operating through a sophisticated molecular cascade that becomes fundamentally altered during aging. Under physiological conditions, TREM2 associates with TYROBP (also known as DAP12) to form a functional receptor complex on microglial cell surfaces. Upon ligand binding—including phospholipids, lipoproteins, and cellu
## 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 factors. During aging, declining NAD+ levels and oxidative stress lead to SIRT1 downregulation, trigge
