**Molecular Mechanism and Rationale**
The pathophysiology of neuromyelitis optica spectrum disorder (NMOSD) centers on the autoimmune targeting of aquaporin-4 (AQP4), a water channel protein predominantly expressed on astrocyte endfeet at the blood-brain barrier. AQP4-IgG autoantibodies bind to the extracellular epitopes of AQP4, triggering complement activation through the classical pathway. This cascade initiates with C1q binding to the Fc portion of AQP4-IgG immune complexes, leading to sequ
## **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
