CNS Aquaporin‐4‐specific B cells connect with multiple B‐cell compartments in neuromyelitis optica spectrum disorder
OBJECTIVES Neuromyelitis optica spectrum disorder (NMOSD) is a severe inflammatory disorder of the central nervous system (CNS) targeted against aquaporin-4 (AQP4). The origin and trafficking of AQP4-specific B cells in NMOSD remains unknown. METHODS Peripheral (n = 7) and splenic B cells (n = 1) recovered from seven NMOSD patients were sorted into plasmablasts, naïve, memory, and CD27-IgD- d...
متن کاملAnti-myelin Oligodendrocyte Glycoprotein in Aquaporin-4 Negative Neuromyelitis Optica Spectrum Disorder
Background: The absence of Aquaporin-4 Antibody (AQP4-Ab) in a fraction of the Neuromyelitis Optica Spectrum Disorder (NMOSD) patients has led to a search for other serologic markers. Myelin Oligodendrocyte Glycoprotein (MOG) is a protein component of the myelin sheets encapsulating the neural fibers. Objectives: We aimed to compare the presence and levels of anti-MOG (Ig-G) in a group of s...
متن کاملTumefactive Brain Lesions in Patients with Neuromyelitis Optica Spectrum Disorder
Background: Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune neurological disorder that is characterized by optic neuritis and longitudinally-extended transverse myelitis lesions in spinal segments. Magnetic Resonance Imaging (MRI) findings are part of the diagnostic process in NMOSD patients, and abnormal lesion patterns may cause deviation from a correct diagnosis. Clinical P...
متن کاملAutoimmune aquaporin-4 myopathy in neuromyelitis optica spectrum.
IMPORTANCE Documentation of muscle pathology compatible with targeting of sarcolemmal aquaporin-4 (AQP4) by complement-activating IgG implies involvement of organs beyond the central nervous system in neuromyelitis optica spectrum disorders. OBSERVATIONS We report on a 51-year-old woman who had relapsing optic neuritis, transverse myelitis, AQP4-IgG seropositivity, and recurrent myalgias with...
متن کاملConvergence spasm due to aquaporin-positive neuromyelitis optica spectrum disorder
A female 27 presented with nausea and diplopia for 1 week. On examination she had normal vertical gaze but would develop convergence with miosis whenever she made horizontal saccades. Pupils were 6 mm and unreactive to light. MRI showed extensive hyperintensity in the dorsal midbrain and thalamus. Spinal MRI and CSF were both normal. Serum aquaporin-4-antibody was positive. She was treated with...
