The choroid plexuses (CPs) are highly vascularized epithelial structures lying in the brain ventricles, forming the blood-cerebrospinal fluid (CSF) barrier. CPs are composed of a monolayer of cuboidal epithelial cells, derived from ependymal cells (EPCs), joined by tight junctions, and surrounding a core of fenestrated capillaries. Choroid plexus epithelial cells (CPECs) secrete most of the CSF through poorly understood mechanisms that involve aquaporins (AQPs) and various solute transport proteins like the Na+-K+-2Cl- cotransporter 1 (NKCC1). It is thought that the concerted action of these membrane proteins directs the transepithelial movement of solutes and water across CPECs. Net water movement across …
