Description
The abstract mentions that AQP4 antibody discovery provided rationale for targeting humoral immune responses, but doesn’t address which specific therapeutic approaches work best or when they should be applied during disease progression. This knowledge gap limits optimization of treatment protocols for NMO patients.
