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

open access: yes, 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

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

open access: yes, 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,

Barley plasma membrane intrinsic proteins (PIP aquaporins) as water and CO2 transporters [PDF]

open access: yes, 2008
We identified barley aquaporins and demonstrated that one, HvPIP2;1, transports water and CO2. Regarding water homeostasis in plants, regulations of aquaporin expression were observed in many plants under several environmental stresses. Under salt stress,

Genetic deletion of laminin isoforms β2 and γ3 induces a reduction in Kir4.1 and aquaporin-4 expression and function in the retina. [PDF]

open access: yesPLoS ONE, 2011
Glial cells such as retinal Müller glial cells are involved in potassium ion and water homeostasis of the neural tissue. In these cells, inwardly rectifying potassium (Kir) channels and aquaporin-4 water channels play an important role in the process of ...

Serum Neurofilament Light and GFAP Are Associated With Disease Severity in Inflammatory Disorders With Aquaporin-4 or Myelin Oligodendrocyte Glycoprotein Antibodies

open access: yesFrontiers in Immunology, 2021
Objective: To evaluate the potential of serum neurofilament light (sNfL) and serum glial fibrillary acidic protein (sGFAP) as disease biomarkers in neuromyelitis optica spectrum disorder (NMOSD) with aquaporin-4 antibody (AQP4-ab) or myelin ...

Cerebral Microcirculation, Perivascular Unit, and Glymphatic System: Role of Aquaporin-4 as the Gatekeeper for Water Homeostasis

open access: yesFrontiers in Neurology, 2021
In the past, water homeostasis of the brain was understood as a certain quantitative equilibrium of water content between intravascular, interstitial, and intracellular spaces governed mostly by hydrostatic effects i.e., strictly by physical laws.

Expression and localization of Aquaporin 1a in the sea-bass (Dicentrarchus labrax) during ontogeny [PDF]

open access: yes, 2011
The successful establishment of a species in a given habitat depends on the ability of each of its developing stages to adapt to the environment. In order to understand this process we have studied the adaptation of a euryhaline fish, the sea-bass ...

Evaluation of aquaporin‐4 antibody assays [PDF]

open access: yesClinical and Experimental Neuroimmunology, 2014
AbstractAquaporin‐4 (AQP4) is a water channel protein that is most highly, but not exclusively, expressed in the central nervous system. In 2005 AQP4 was shown to be the antigenic target of neuromyelitis optica‐immunoglobulin G (NMO‐IgG, or AQP4‐IgG), an antibody found specifically in patients with NMO and in formes frustes of NMO, such as ...
