嚢胞性線維症
Cystic fibrosis is a progressive, genetic disease that is linked to CF transmembrane regulator (CFTR) dysfunction. Blockage of this channel by certain cytoplasmic, negatively-charged substances results in reduced chloride ion and bicarbonate anion transport, as well as reduced fluid and salt secretion. This results in a buildup of thick mucus, which is characteristic of cystic fibrosis.
