neuromyelitis optica and nucleotide variations of aquaporin-4 gene
purpose: neuromyelitis opitca (nmo) is an autoimmune disease that relates to deposition of anti-aquaporin-4 (aqp4) igg in the central nervous system (cns). however, called seronegative nmo when patients are negative for aqp4 antibody. nevertheless, nmo is most probably an antibody mediated disease. the aim of this study was to assess the association between seronegative nmo disease and variatio...
متن کاملSeverely exacerbated neuromyelitis optica rat model with extensive astrocytopathy by high affinity anti-aquaporin-4 monoclonal antibody
INTRODUCTION Neuromyelitis optica (NMO), an autoimmune astrocytopathic disease associated with anti-aquaporin-4 (AQP4) antibody, is characterized by extensive necrotic lesions preferentially involving the optic nerves and spinal cord. However, previous in-vivo experimental models injecting human anti-AQP4 antibodies only resulted in mild spinal cord lesions compared to NMO autopsied cases. Here...
متن کاملDifferent Phenotypes at Onset in Neuromyelitis Optica Spectrum Disorder Patients with Aquaporin-4 Autoimmunity
BACKGROUND Although rare, brain abnormalities without optic neuritis (ON) or transverse myelitis (TM) diagnosed with neuromyelitis optica spectrum disorder (NMOSD) have been reported in patients positive for the aquaporin-4 (AQP4) antibody. OBJECTIVE To analyze demographic and clinical differences among NMOSD patients without ON or TM, those with either ON or TM, and patients with simultaneou...
متن کاملIlluminating neuromyelitis optica pathogenesis.
W hat is the most important moment in the history of a disease? Let us consider neuromyelitis optica (NMO), which was coined by French neurologist Eugene Devic in 1894 for a disease believed until recently to be a subtype of multiple sclerosis (MS). The discovery (in 2004) of a disease-specific biomarker for NMO revolutionized our understanding of both NMO and MS (1). In PNAS, Hinson et al. (2)...
متن کاملAntibody to Aquaporin 4 in the Diagnosis of Neuromyelitis Optica
BACKGROUND Neuromyelitis optica (NMO) is a demyelinating disease of the central nervous system (CNS) of putative autoimmune aetiology. Early discrimination between multiple sclerosis (MS) and NMO is important, as optimum treatment for both diseases may differ considerably. Recently, using indirect immunofluorescence analysis, a new serum autoantibody (NMO-IgG) has been detected in NMO patients....
