Induction of aquaporin 4-reactive antibodies in Lewis rats immunized with aquaporin 4 mimotopes [PDF]

open access: yesActa Neuropathologica Communications, 2020
Most cases of neuromyelitis optica spectrum disorders (NMOSD) harbor pathogenic autoantibodies against the water channel aquaporin 4 (AQP4). Binding of these antibodies to AQP4 on astrocytes initiates damage to these cells, which culminates in the ...

Skull diploë is rich in aquaporin-4 [PDF]

open access: yesHeliyon, 2020
Aquaporin-4 (AQP4) is a water conducting membrane integral protein channel which is widely expressed in the astrocyte system of the brain. During the development of the AQP4 positron emission tomography (PET) imaging agent [11C]TGN-020 (N-(1,3,4 ...

Aquaporin-4 and Parkinson's Disease. [PDF]

open access: yesInt J Mol Sci
The water-selective channel aquaporin-4 (AQP4) is implicated in water homeostasis and the functioning of the glymphatic system, which eliminates various metabolites from the brain tissue, including amyloidogenic proteins. Misfolding of the α-synuclein protein and its post-translational modifications play a crucial role in the development of Parkinson’s

Co-occurrence of aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder and hepatocellular carcinoma: A case report [PDF]

open access: yesJournal of International Medical Research
Neuromyelitis optica spectrum disorder is a rare, relapsing autoimmune disease in which the immune system attacks the central nervous system, primarily the optic nerves and spinal cord.

Antibody to aquaporin 4 in the diagnosis of neuromyelitis optica.

open access: yesPLoS Medicine, 2007
BackgroundNeuromyelitis 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 ...

Aquaporin-3 and aquaporin-4 are sorted differently and separately in the trans-Golgi network. [PDF]

open access: yesPLoS ONE, 2013
Aquaporin-3 (AQP3) and aquaporin-4 (AQP4) are homologous proteins expressed in the basolateral plasma membrane of kidney collecting duct principal cells, where they mediate the exit pathway for apically reabsorbed water.

Osmotic adaptation of nucleus pulposus cells: the role of aquaporin 1, aquaporin 4 and transient receptor potential vanilloid 4 [PDF]

open access: yesEuropean Cells & Materials, 2021
The microenvironment of the nucleus pulposus is hyperosmotic and fluctuates diurnally due to mechanical loading. Changes in extracellular osmolality result in cell volume alterations, responsiveness to such changes is essential for cellular homeostasis ...

α-Actinin 4 Links Vasopressin Short-Term and Long-Term Regulation of Aquaporin-2 in Kidney Collecting Duct Cells

open access: yesFrontiers in Physiology, 2021
Water permeability of the kidney collecting ducts is regulated by the peptide hormone vasopressin. Between minutes and hours (short-term), vasopressin induces trafficking of the water channel protein aquaporin-2 to the apical plasma membrane of the ...

Aquaporin-4 autoimmunity [PDF]

open access: yesNeurology Neuroimmunology & Neuroinflammation, 2015
Neuromyelitis optica (NMO) and a related spectrum of inflammatory CNS disorders are unified by detection of a serum autoantibody specific for the aquaporin-4 (AQP4) water channel, which is abundant in astrocytic foot processes. The classic clinical manifestations of NMO are optic neuritis and longitudinally extensive transverse myelitis.
