According to a study from Ottawa, Canada, "To elucidate the role of epithelial sodium channels (ENaCs) and Na+-K+-ATPase in Na+ transport by the choroid plexus, we studied ENaC expression and Na+ transport in the choroid plexus. Lateral ventricle choroid plexuses were obtained from young male Wistar, Dahl salt-resistant (SS.BN13), and Dahl salt-sensitive (SS/MCW) rats on a regular (0.3%) or high-(8.0%) salt diet."

"The effects of ENaC blocker benzamil and Na+-K+-ATPase blocker ouabain on sodium transport were evaluated by measuring the amounts of retained Na-22(+) ...
