## Molecular Mechanism and Rationale
The temporal TET2-mediated hydroxymethylation cycling hypothesis centers on the dysregulation of Ten-Eleven Translocation 2 (TET2) enzyme activity in aged neurons and its profound impact on epigenetic landscape maintenance. TET2, a member of the α-ketoglutarate-dependent dioxygenase family, catalyzes the oxidation of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), initiating the DNA demethylation pathway crucial for transcriptional plasticity. In h
**Molecular Mechanism and Rationale**
The fundamental basis of this therapeutic hypothesis centers on the epigenetic dysregulation that underlies astrocyte polarization in neurodegenerative diseases. Ten-eleven translocation methylcytosine dioxygenase 2 (TET2) serves as a critical epigenetic enzyme responsible for catalyzing the oxidation of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), initiating active DNA demethylation processes. In the context of neurodegeneration, astrocytes un
