**Molecular Mechanism and Rationale**
Histone deacetylase 6 (HDAC6) represents a unique member of the class IIb HDAC family, distinguished by its predominantly cytoplasmic localization and dual catalytic domains that confer distinctive substrate specificity. Unlike nuclear HDACs that primarily regulate gene transcription through histone modification, HDAC6 functions as a critical regulator of cytoplasmic protein acetylation, particularly targeting α-tubulin and heat shock protein 90 (Hsp90). Th
## Mechanistic Overview
HDAC6 Inhibition for Dual Restoration of Microtubule Stability and Autophagic Tau Clearance starts from the claim that modulating HDAC6 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview HDAC6 Inhibition for Dual Restoration of Microtubule Stability and Autophagic Tau Clearance starts from the claim that Selective HDAC6 inhibitors (T-518, Tubastatin A, ACY-1215) simultaneously i
