Pulomonary ionocytes make up about one percent of the cells in the lung and are thought to be responsible for cystic fibrosis, the incurable multiorgan disease which affects more than 70 000. The key defect in cystic fibrosis is loss of chloride conductance, but mutations of the cystic fibrosis gene product, the cftr, have multiple effects on cell physiology new results help to reconcile these facts.

Cystic fibrosis transmembrane conductance regulator (cftr) is a glycoprotein found in the plasma membrane of exocrine organ cells, and is co. In cystic fibrosis lungs, inactive or inefficient functioning cftr results in impaired chloride transport and enhanced sodium absorption across airway epithelial cells. A cystic fibrosis mutation that causes an incorrectly shaped cftr channel would reduce the effects of cholera because it would prevent so many chloride ions leaving the cell and building up in the lumen. As cystic fibrosis is the result of an autosomal recessive disorder, the sufferer will have to of inherited two copies of the mutated gene (one from each parent) in order to be affected by the disease.

The fight against cystic fibrosis has taken a major step forward, with new research showing that cells causing the debilitating genetic disorder could be successfully replaced with healthy ones. The cystic fibrosis is regarded to be most common among the northern europeans and was first recognized in 1938 by dorothy andersen (thomson and ann, 17) the disease is diagnosed by methods including newborn screening, sweat testing, and genetic testing.
