Web15 May 1999 · Immunodetection of CFTR on the luminal surface of pseudostratified respiratory epithelia, submucosal glands, and reabsorptive sweat ducts corresponds with previous findings (19, 27, 29, 33); it fits in with the role of CFTR for chloride and fluid secretion on the surface of the larger airways and submucosal glands and reabsorption of … WebThe CFTR gene is on at lower levels in cells that line certain reproductive organs in both men and women, and in sweat glands in the skin. The cells that make CFTR protein form a barrier between the body and the spaces inside of it.

Webin which CFTR is highly expressed; in particular, glan-dular epithelia. The disease primarily manifests in the lungs, pancreas, gastrointestinal tract, vas deferens and sweat glands, although airway disease is the main cause of morbidity and mortality. In the lungs, cystic fibrosis results in mucus accumulation that compromises the WebOne of CFTR's primary roles in the lungs is to maintain homoeostasis of the airway surface liquid layer through its function as a chloride channel and its regulation of the epithelial …
WebAnother example is that carriers have pilocarpine-stimulated sweat Cl − concentrations that lie between control and CF values ; sweat Cl − concentration depends on CFTR-mediated Cl − absorption by epithelia in the sweat gland duct. This abnormality may explain the increased risk for dehydration and fluid and electrolyte disorders found in this study.
