Lung epithelial ion transport in neonatal lung disease.

Abstract excerpt

Lung epithelial ion transport promotes salt and water movement across the fetal and neonatal lung epithelium. The mechanism is dependent on basolateral membrane Na-K-ATPase and the apical membrane Cl(-) and Na(+) channels. During fetal life active secretion of Cl(-) and parallel movement of Na(+) across the epithelium into the developing lung lumen induce accumulation of liquid into the future airspaces....
