Aquaporin 4 as a NH3 Channel [PDF]
Journal of Biological Chemistry, 2016 Ammonia is a biologically potent molecule, and the regulation of ammonia levels in the mammalian body is, therefore, strictly controlled. The molecular paths of ammonia permeation across plasma membranes remain ill-defined, but the structural similarity of water and NH3 has pointed to the aquaporins as putative NH3-permeable pores. Accordingly, a range

Aquaporin-4 and brain edema [PDF]
Pediatric Nephrology, 2007 Aquaporin-4 (AQP4) is a water-channel protein expressed strongly in the brain, predominantly in astrocyte foot processes at the borders between the brain parenchyma and major fluid compartments, including cerebrospinal fluid (CSF) and blood. This distribution suggests that AQP4 controls water fluxes into and out of the brain parenchyma.

Aquaporin-4 and Cerebrovascular Diseases [PDF]
International Journal of Molecular Sciences, 2016 Cerebrovascular diseases are conditions caused by problems with brain vasculature, which have a high morbidity and mortality. Aquaporin-4 (AQP4) is the most abundant water channel in the brain and crucial for the formation and resolution of brain edema.

Aquaporin 4 and neuromyelitis optica [PDF]
The Lancet Neurology, 2012 Neuromyelitis optica is an inflammatory demyelinating disorder of the CNS. The discovery of circulating IgG1 antibodies against the astrocyte water channel protein aquaporin 4 (AQP4) and the evidence that AQP4-IgG is involved in the development of neuromyelitis optica revolutionised our understanding of the disease.

Aquaporin-4 expression in the human choroid plexus [PDF]
Cellular and Molecular Life Sciences, 2021 Abstract The choroid plexus (CP) consists of specialized ependymal cells and underlying blood vessels and stroma producing the bulk of the cerebrospinal fluid (CSF). CP epithelial cells are considered the site of the internal blood-cerebrospinal fluid barrier, show epithelial characteristics (basal lamina, tight junctions), and ...

Isolated dysphagia due to aquaporin-4 autoimmunity
The Turkish Journal of Gastroenterology, 2012 İstanbul Bilim Üniversitesi, Tıp Fakültesi.Neuromyelitis optica (NMO) is an inflammatory, demyelinating disease that affects the spinal cord and optic nerves and is associated with aquaporin- 4 antibodies (Aqp-4 Ab).

Rinsho Shinkeigaku, 2008 In human body, there are thirteen water channels but their expression patterns are tissue specific. Aquaporin-4 (AQP4) is a predominantly expressed water channel in the mammalian brain and an important drug target for treatment of cerebral edema, bipolar disorder, and mesial temporal lobe epilepsy.

Bisacodyl overcomes morphine-induced constipation by decreasing colonic Aquaporin-3 and Aquaporin-4 expression [PDF]
Research Results in Pharmacology, 2022 Introduction: Morphine is an opioid prescribed to treat aches and pains. However, morphine often causes opioid-induced constipation (OIC). Aquaporin (AQP) transporters, especially AQP3 and AQP4, play an essential role in mediating constipation. Bisacodyl
