Abstract Background: Choroid plexus (CP) is a branched structure made up of a single layer of epithelial cells and blood capillaries, forming the blood-CSF-barrier. The CSF (cerebrospinal fluid) is mainly produced from the CP. Aquaporin1 (AQP1), water channels that are highly expressed on the apical side of the membrane in choroid plexus, have a major role in mediating water transport across th...
متن کاملDistribution of sodium transporters and aquaporin-1 in the human choroid plexus.
The choroid plexus epithelium secretes electrolytes and fluid in the brain ventricular lumen at high rates. Several channels and ion carriers have been identified as likely mediators of this transport in rodent choroid plexus. This study aimed to map several of these proteins to the human choroid plexus. Immunoperoxidase-histochemistry was employed to determine the cellular and subcellular loca...
متن کاملInwardly rectifying K+ channel Kir7.1 is highly expressed in thyroid follicular cells, intestinal epithelial cells and choroid plexus epithelial cells: implication for a functional coupling with Na+,K+-ATPase.
A novel inwardly rectifying K+ channel, Kir7.1, with unique pore properties, was cloned recently. Working in the field of osmoregulation, we have also identified the same human and rat channel and found that the channel is unique not only in its pore sequence but also in its dense localization in the follicular cells of the thyroid gland. Northern blot analysis revealed that the channel message...
متن کاملKCNE2 forms potassium channels with KCNA3 and KCNQ1 in the choroid plexus epithelium.
Cerebrospinal fluid (CSF) is crucial for normal function and mechanical protection of the CNS. The choroid plexus epithelium (CPe) is primarily responsible for secreting CSF and regulating its composition by mechanisms currently not fully understood. Previously, the heteromeric KCNQ1-KCNE2 K(+) channel was functionally linked to epithelial processes including gastric acid secretion and thyroid ...
متن کاملTWIST-1 is overexpressed in neoplastic choroid plexus epithelial cells and promotes proliferation and invasion.
The pathogenesis of choroid plexus papillomas, intraventricular papillary neoplasms most often occurring sporadically in children and young adults, remains poorly understood. To identify pathways operative in the development of choroid plexus papillomas, gene expression profiles obtained from laser-microdissected human choroid plexus papilloma cells (n = 7) were compared with that of normal cho...
