Key blood-brain barrier ion transport systems. Ion transporters and channels expressed within the BBB mediates the movement of Na+, K+, Cl-, HCO3-, H+ and Ca2+ into and out of the BBB specific cells. The BBB ion transport is important for regulation of key ionic concentrations in the brain (H+, K+, Ca2+), the uptake and extrusion of trace metals, fluid secretion, intracellular volume, pH and Ca2+ homeostasis.
