Exploring cell membrane water exchange in aquaporin-4-deficient ischemic mouse brain using diffusion-weighted MRI

European Radiology Experimental, 2021
Background Aquaporin-4 is a membrane channel protein that is highly expressed in brain astrocytes and facilitates the transport of water molecules. It has been suggested that suppression of aquaporin-4 function may be an effective treatment for reducing ...

Aquaporin Expression Contributes to Human Transurothelial Permeability In Vitro and Is Modulated by NaCl [PDF]

, 2012
It is generally considered that the bladder is impervious and stores urine in unmodified form on account of the barrier imposed by the highly-specialised uro-epithelial lining.

Neurohypophysial and paracrine vasopressinergic signaling regulates aquaporin trafficking to hydrate marine teleost oocytes

Frontiers in Endocrinology, 2023
The dual aquaporin (Aqp1ab1/Aqp1ab2)-mediated hydration of marine teleost eggs, which occurs during oocyte meiosis resumption (maturation), is considered a key adaptation underpinning their evolutionary success in the oceans.

Structure determination of membrane-located complexes: Aquaporin 8 and YscC secretin [PDF]

, 2011
A biological membrane is key to the life of a cell. In all living cells a biological membrane separates a inner life and an outer environment. Plasma membrane has many functions such as responding to external signals and transmitting them into the cell,

Prokaryotic Aquaporins [PDF]

Cells, 2019
Aquaporins are integral membrane proteins that facilitate the diffusion of water and other small, uncharged solutes across the cellular membrane and are widely distributed in organisms from humans to bacteria. However, the characteristics of prokaryotic aquaporins remain largely unknown. We investigated the distribution and sequence characterization of

Contrasting disease patterns in seropositive and seronegative neuromyelitis optica: A multicentre study of 175 patients [PDF]

, 2012
BACKGROUND: The diagnostic and pathophysiological relevance of antibodies to aquaporin-4 (AQP4-Ab) in patients with neuromyelitis optica spectrum disorders (NMOSD) has been intensively studied. However, little is known so far about the clinical impact of

Aquaporins: relevance to cerebrospinal fluid physiology and therapeutic potential in hydrocephalus

Cerebrospinal Fluid Research, 2010
The discovery of a family of membrane water channel proteins called aquaporins, and the finding that aquaporin 1 was located in the choroid plexus, has prompted interest in the role of aquaporins in cerebrospinal fluid (CSF) production and consequently ...

Eph-ephrin Signaling Affects Eye Lens Fiber Cell Intracellular Voltage and Membrane Conductance

Frontiers in Physiology, 2021
The avascular eye lens generates its own microcirculation that is required for maintaining lifelong lens transparency. The microcirculation relies on sodium ion flux, an extensive network of gap junction (GJ) plaques between lens fiber cells and ...

Gas-tight triblock-copolymer membranes are converted to CO2 permeable by insertion of plant aquaporins [PDF]

, 2012
We demonstrate that membranes consisting of certain triblock-copolymers were tight for CO2. Using a novel approach, we provide evidence for aquaporin facilitated CO2 diffusion.
