We found that the resultant
aquaporin-incorporated biomimetic membrane allows water to pass through it faster and also display lower salt leakage than a membrane without
aquaporin.
Aquaporin 4 was present in high amounts in astrocytes and ependymocytes and in low amounts in the choroidal plexus epithelia and leptomeningeal cells.
Among these agents,
aquaporins are a family of hydrophobic and small integral membrane proteins that act as water selective pores, facilitating water transport along a favorable osmotic gradient (5).
There are 13 different types of
aquaporin that react to different factors.
More than just water channels: unexpected cellular roles of
aquaporins.
For example, Danish
aquaporin membrane company
Aquaporin A/S, with the support of EWI funding, has collaborated with the Singapore Membrane Technology Centre (SMTC) of NEWRI to develop a novel
aquaporin enhanced biomimetic membrane for application in desalination and water reclamation.
To investigate the role of
aquaporins in desiccation avoidance in xerophytic ferns gametophytes, Cheilanthes lanosa gametophytes were poisoned with micromolar mercury solutions, which block
aquaporin channels, exposed to several osmolytes, and quantified the efflux of water from the cells was quantified.
intraperitoneal, DPO = darbepoietin, Cr = creatinine, TNF-[alpha] = tumour necrosis factor-alpha, IL-2 = interleukin-2, LDH = lactate dehy- drogenase, rHuEPO = recombinant human erythropoietin, PTC = proximal tubule cell, MPO = myeloperoxidase, NAG = N-acetylglutamate, AST = aspartate aminotransferase (indicates reperfusion injury), FENa-fractional excretion of Na+, AQP =
aquaporin, NHE = Na+/H+ exchanger, TSC = thiazide-sensitive sodium chloride cotransporter, bcl-2 = oncogene activated by chromosome translocation in human B-cell lymphomas, JNK = c-Jun N-terminal kinase, HSP70 = heat shock protein 70.
Kabashima K, Shimauchi T, Kobayashi M et al: Aberrant
aquaporin 5 expression in the sweat gland in aquagenic wrinkling of the palms.
Similarly we have had great innovations in our exclusive pharmacy range of products Eucerin with the launch of
AQuaporin, which has been a massive hit with pharmacists and consumers alike as a patented Nobel prize winning technology makes it way for the first time into an affordable skincare product, delivering maximum hydration to dry skin sufferers," he concluded.
Novel treatment for lithium-induced nephrogenic diabetes insipidus rat model using the Sendai-virus vector carrying
aquaporin 2 gene.
13) Progesterone downregulates, or decreases,
aquaporin activity in the injured brain tissue, while upregulating, or enhancing,
aquaporin activity in the walls of the cerebral ventricles.
