## 1. Molecular Mechanism and Rationale
The fundamental premise underlying astrocyte-mediated neuronal epigenetic rescue centers on the strategic manipulation of histone deacetylase (HDAC) activity through engineered paracrine signaling. HDACs comprise a family of 18 zinc-dependent enzymes divided into four classes (I, IIa, IIb, and IV) that catalyze the removal of acetyl groups from lysine residues on histone proteins. This deacetylation drives chromatin condensation into heterochromatin, gene
This hypothesis proposes that age-related TREM2 signaling dysfunction drives microglia into a senescent state that fundamentally rewires astrocyte-microglia communication networks, creating a pathological feedback loop in neurodegeneration. Under normal conditions, TREM2/TYROBP signaling maintains microglial homeostasis and supports neuroprotective astrocyte-microglia cross-talk through regulated release of IL-33, lactate, and ATP. However, during aging, accumulated DNA damage and metabolic stre
