Bioelectric properties of chloride channels in human, pig, ferret, and mouse airway epithelia.

ABSTRACT: The development of effective therapies for cystic fibrosis (CF) requires animal models that can appropriately reproduce the human disease phenotype. CF mouse models have demonstrated cAMP-inducible, non-CF transmembrane conductance regulator (non-CFTR) chloride transport in conducting airway epithelia, and this property is thought to be responsible for the lack of a spontaneous CF-like phenotype in the lung. Thus, an understanding of species diversity in airway epithelial electrolyte transport and CFTR function is critical to developing better models for CF. Two species currently being used in attempts to develop better animal models of CF include the pig and ferret. In the study reported here, we sought to comparatively characterize the bioelectric properties of in vitro polarized airway
