Background: Neuromyelitis optica (NMO) is a demyelinating disorder involving optic neuritis and transverse myelitis.
Background: NMO-IgG autoantibody is now considered a useful serum biomarker of neuromyelitis optica (NMO). A series of clinical and pathological observations suggest that NMO-IgG may play a central role in NMO physiopathology. Objective: The aim of this in vitro-based study was to characterize molecular and functional consequences of interaction between NMO-IgG and primary cultures of astrocytes.
Neuromyelitis optica (NMO; Devic’s disease) and the NMO spectrum disorders are idiopathic inflammatory demyelinating disorders that affect the central nervous system and have a predilection for optic nerves and spinal cord. The identification of NMO-IgG as a disease-specific marker and aquaporin 4 as the target antigen has renewed interest in NMO.
