Paracellular bicarbonate flux across human cystic fibrosis airway epithelia tempers changes in airway surface liquid pH

KEY POINTS: Cl(−) and HCO(3) (−) had similar paracellular permeabilities in human airway epithelia. P(Cl)/P(Na) of airway epithelia was unaltered by pH 7.4 vs. pH 6.0 solutions. Under basal conditions, calculated paracellular HCO(3) (−) flux was secretory. Cytokines that increased airway surface liq...
