**Molecular Mechanism and Rationale**
The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) pathway represents a critical molecular switch governing microglial homeostasis and their transition from neuroprotective to neurotoxic phenotypes during aging and neurodegeneration. TREM2 functions as a transmembrane receptor exclusively expressed on microglia in the central nervous system, forming a signaling complex with the adaptor protein TYROBP (also known as DAP12). Under physiological cond
## 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
