H95 Is a pH-Dependent Gate in Aquaporin 4.
Aquaporin 4 (AQP4) is a transmembrane protein from the aquaporin family and is the predominant water channel in the mammalian brain. The regulation of permeability of this protein could be of potential therapeutic use to treat various forms of damage to the nervous tissue. In this work, based on data obtained from in silico and in vitro studies, a pH sensitivity that regulates the osmotic water...
متن کاملAquaporin 4 as a NH3 Channel.
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 of aquaporins from mammals, plants, fungi,...

This paper presents a re-analysis of Lauer & Postman's (1994) nding that the Abell cluster inertial frame (ACIF), deened by the 119 Abell clusters within 15,000 km s 1 , is moving at almost 700 km s 1 with respect to the cosmic microwave background. Such a motion is inconsistent with most cosmological models at a conndence level of 95% or higher. We examine the use of the relation between the m...
متن کاملAquaporin-4 autoantibodies in a paraneoplastic context.
BACKGROUND The neuromyelitis optica IgG autoantibody (NMO-IgG) is a validated biomarker for NMO and an emerging spectrum of inflammatory central nervous system-demyelinating disorders. Its antigen is the astrocytic water channel aquaporin-4; NMO-IgG has not been described in a cancer context. OBJECTIVES To report (1) neurologic and oncologic correlates for patients incidentally identified as ...
متن کاملAquaporin-4 autoimmunity
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. Newly recognized manifestations of AQP4 autoimmunity incl...
