**Molecular Mechanism and Rationale**
The aquaporin-4 (AQP4) water channel represents the most abundant water channel in the central nervous system, with its polarized localization at astrocyte endfeet being critical for proper glymphatic function. Under physiological conditions, AQP4 is highly concentrated at perivascular astrocyte membranes through a sophisticated molecular anchoring system centered on the dystrophin-associated protein complex (DAPC). This anchoring complex consists of severa
## **Molecular Mechanism and Rationale**
Aquaporin-4 (AQP4) represents the predominant water channel in the central nervous system, constituting approximately 50-60% of all aquaporin expression in astrocytes. This tetrameric transmembrane protein localizes primarily to astrocytic endfeet at the blood-brain barrier and ependymal surfaces, forming the structural foundation of the glymphatic system. Under normal physiological conditions, AQP4 facilitates bidirectional water transport across cellul
