Experimental Models of Neuromyelitis Optica
نویسندگان
چکیده
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, circulating antibodies against aquaporin 4 can reach the brain and induce lesions in the central nervous system, which are closely similar to those, seen in patients with neuromyelitis optica.

Neuromyelitis 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...

Recent work from our laboratory, using different models of experimental neuromyelitis optica spectrum disorder (NMOSD), has led to a number of observations that might be highly relevant for NMOSD patients. For example: (i) in the presence of neuromyelitis optica immunoglobulin G, astrocyte-destructive lesions can be initiated by CD4+ T cells when these cells recognize aquaporin 4 (AQP4), but al...

Devic's neuromyelitis optica is an inflammatory demyelinating disorder normally restricted to the optic nerves and spinal cord. Since the identification of a specific autoantibody directed against aquaporin 4, neuromyelitis optica-immunoglobulin G/aquaporin 4 antibody, neuromyelitis optica has been considered an entity distinct from multiple sclerosis. Recent findings indicate that the neuromye...

Background: Neuromyelitis Optica (NMO) is an autoimmune inflammation of the central nervous system in which autoantibodies are released against Aquaporin-4 (AQP-4), astrocytic water channels. The disease is characterized by transverse myelitis and optic neuritis. Viruses could be inflammatory agents in the brain. Due to such inflammatory reactions, autoantibodies would cross the blood brain bar...
