CFTR and cystic fibrosis: (v) Although some studies have reported altered inflammatory and apoptotic responses in CF vs nonCF or CFTR-corrected airway epithelia exposed to P. aeruginosa [32–37], P. aeruginosa swarming and immobilization on CFBE41o- cells was unaffected by CFTR expression and it seems unlikely that release of amino acids from wounded epithelial cells would be affected by the presence or absence of CFTR in the cells.
