Correlation between serum AQP-4 antibody, inflammatory cytokines and recurrence of neuromyelitis optica in patients with chronic insomnia

open access: yesZhongguo linchuang yanjiu, 2022
Objective To investigate the levels of serum aquaporin 4(AQP-4) antibodies and cytoinflammatory factors in patients with neuromyelitis optica(NMO) complicated with chronic insomnia and their correlation with the recurrence of NMO. Methods A total of 103

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

open access: yes, 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.

A comparison of aquaporin expression in mosquito larvae (Aedes aegypti) that develop in hypo-osmotic freshwater and iso-osmotic brackish water.

open access: yesPLoS ONE, 2020
The mosquito Aedes aegypti vectors the arboviral diseases yellow fever, dengue, Zika and chikungunya. Larvae are usually found developing in freshwater; however, more recently they have been increasingly found in brackish water, potential habitats which ...

Incipient balancing selection through adaptive loss of aquaporins in natural Saccharomyces cerevisiae populations. [PDF]

open access: yesPLoS Genetics, 2010
A major goal in evolutionary biology is to understand how adaptive evolution has influenced natural variation, but identifying loci subject to positive selection has been a challenge.

Distinct serum and cerebrospinal fluid cytokine and chemokine profiles in autoantibody-associated demyelinating diseases

open access: yesMultiple Sclerosis Journal - Experimental, Translational and Clinical, 2019
Background Demyelinating diseases of the central nervous system associated with autoantibodies against aquaporin-4 and myelin-oligodendrocyte-glycoprotein are mediated by different immunopathological mechanisms compared to multiple sclerosis.

Adenylate Cyclase 6 Determines cAMP Formation and Aquaporin-2 Phosphorylation and Trafficking in Inner Medulla [PDF]

open access: yesJournal of the American Society of Nephrology, 2010
Arginine vasopressin (AVP) enhances water reabsorption in the renal collecting duct by vasopressin V₂ receptor (V₂R)-mediated activation of adenylyl cyclase (AC), cAMP-promoted phosphorylation of aquaporin-2 (AQP2), and increased abundance of AQP2 on the apical membrane.

The role of aquaporin-4 in optic nerve head astrocytes in experimental glaucoma.

open access: yesPLoS ONE, 2021
PurposeTo study aquaporin channel expression in astrocytes of the mouse optic nerve (ON) and the response to IOP elevation in mice lacking aquaporin 4 (AQP4 null).MethodsC57BL/6 (B6) and AQP4 null mice were exposed to bead-induced IOP elevation for 3 ...

Role of Aquaporin-6 in Rat Parotid Secretory Granules

open access: yesJournal of Oral Biosciences, 2011
Abstract Aquaporin-6 (AQP6) is a unique member of the family of AQP water channels and is involved in anion permeability. AQP6 was initially discovered in the cytoplasm of kidney cells as a kidney-specific AQP; however, subsequent studies revealed that the brain, inner ear, vestibular and intestines also express AQP6.
