The choroid plexus epithelium is a cuboidal cell monolayer, which produces the majority of
the cerebrospinal fluid. The concerted action of a variety of integral membrane proteins …

Abstract Knowledge of the diversity of ion channel form and function has increased
enormously over the last 25 years. The initial impetus in channel discovery came with the …

In vitro perfused rat thick ascending limbs of Henle's loop (TAL) were used (n= 260) to
analyse the conductance properties of the luminal membrane applying the patch-clamp …

The choroid plexuses are involved in cerebrospinal fluid (CSF) secretion and CSF K
homeostasis. We examined K transport mechanisms present in the isolated rat choroid …

Using the patch-clamp technique we have identified a Ca 2+-sensitive, voltage-dependent,
maxi-K+ channel on the basolateral surface of rat pancreatic duct cells. The channel had a …

1. The interaction between Cl‐, K+ and H2O fluxes were studied in the ventricular
membrane of the choroid plexus epithelium from Necturus maculosus by means of ion …

The choroid plexus is a tissue located in the lateral ventricles of the brain and is composed
mainly of choroid plexus epithelium cells. The main function is currently thought to be the …

The choroid plexus is a specialized tissue that lines subdomains within the four ventricles of
the brain where most of the cerebrospinal fluid is produced. Maintenance of an equilibrium …

Using patch-clamp techniques, we have studied Ca 2+-activated K+ channels in the
basolateral membrane of freshly isolated epithelial cells from rabbit distal colon. Epithelial …

Water crosses cell membranes by passive transport and by secondary active cotransport
along with ions. While the first concept is well established, the second is new. The two …
