Activation of DF508 CFTR in CF airway epithelial cell lines and CF nasal epithelial cells by S-nitrosoglutathione
BACKGROUND: It has been suggested that low microM concentrations of S-nitrosoglutathione (GSNO), an endogenous bronchodilator, may promote maturation of the defective cystic fibrosis (CF) transmembrane conductance regulator (CFTR). Because nitric oxide (NO) and GSNO levels appear to be low in the CF airway, there is an interest in the possibility that GSNO replacement could be of therapeutic benefit in CF. METHODS: The effect of GSNO on chloride
