WebThe CFTR gene provides instructions for making a protein called the CF transmembrane conductance regulator (CFTR). This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes. The channel transports negatively charged particles called chloride ions into and out of cells. WebDecrements in CFTR function have been observed in the upper airway, lower airway, colonic epithelium, and sweat duct, suggesting the pervasive nature of the defect in the individuals affected . Beyond epidemiological associations, in vitro and animal studies have confirmed the causal role of cigarette smoking (71–73).
