Experimental Models of Neuromyelitis Optica
Recently a specific auto-antibody response has been found in patients with neuromyelitis optica, which is directed against the astrocytic water channel aquaporin 4. In experimental models these antibodies do not induce disease or lesions in the central nervous system, when present in the circulation of normal rats. However, when T-cell mediated inflammation is induced in such animals, circulati...
متن کاملComplement-dependent and -independent aquaporin 4-antibody-mediated cytotoxicity in human astrocytes: Pathogenetic implications in neuromyelitis optica
Background Neuromyelitis optica (NMO) is an inflammatory disease caused by the aquaporin (AQP)-4-antibody. Pathological studies on NMO have revealed extensive astrocytic damage, as evidenced by the loss of AQP4 and glial fibrillary acidic protein (GFAP), specifically in perivascular regions with immunoglobulin and complement depositions, although other pathological patterns, such as a loss of A...
متن کاملEvidence for classic complement activity in neuromyelitis optica
Sir, – Neuromyelitis optica is a relapsingremitting autoimmune disease associated with the anti-aquaporin-4 antibody (NMOIgG) and complement-mediated perivascular inflammation disease on pathology [1]. Although not specific for NMO, complement deposition is characteristic of the humoral immunopathogenesis. Empiric and laboratory evidence for the involvement of the NMO-IgG as a harmful pathogeni...
متن کاملNeuromyelitis Optica in Children: A Rare Entity
Neuromyelitis optica (also known as Devic's disease or Devic's syndrome) is an uncommon disorder in pediatric age group, and is characterized by acute or subacute optic neuritis and transverse myelitis. Here we report an 11- year- old female child with relapsing Neuromyelitis optica (NMO) confirmed by positive NMO- IgG antibody and had clinical recovery with high dose methyl prednisolone t...
متن کاملNeuromyelitis Optica
An 11-year-old girl developed sudden visual loss in her left eye, preceding subacute myelitis by 9 months. Multifocal lesions in the central nervous system were demonstrated by magnetic resonance imaging. Although unilateral blindness is unusual, the clinical findings predominantly involving the optic nerve and spinal cord were consistent with the diagnosis of neuromyelitis optica (NMO). This c...
