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,

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

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 ...

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 ...

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,

Increased T-cell immunity against aquaporin-4 and proteolipid protein in neuromyelitis optica. [PDF]

open access: yes, 2011
In neuromyelitis optica (NMO), B-cell autoimmunity to aquaporin-4 (AQP4) has been shown to be essential. However, the role of T cells remains ambiguous. Here, we first showed an increase in CD69+ activated T cells in PBMCs during NMO relapses.

Aquaporin 4 and its Relationship with Brain Astrocytomas – Literature Review

open access: yesBrazilian Neurosurgery, 2023
Background Aquaporins (AQPs) are a family of membrane proteins that regulate the osmotic permeability of the plasma membrane. There are described in the literature a total of 13 types of Aquaporins in mammals, each with different places of expression. In
