Localization of cystic fibrosis transmembrane conductance regulator in chloride secretory epithelia. 2015;593:32413251. 1997 Jun 27;109(12-13):457-64. Because the cilia can't move properly, mucus gets stuck in the airways, making it difficult to breathe. See this image and copyright information in PMC. All of these changes prevent the channel from functioning properly, which impairs the transport of chloride ions and the movement of water into and out of cells. The CFTR protein is a chloride channel, a transport protein that moves chloride ions out of epithelial cells (and whose actions also inhibit the uptake of sodium ions by another such channel). Such correction resulted in recovery of CFTR protein levels at the PM (Igreja et al., 2016). doi: 10.1152/physrev.1999.79.1.S23. The study of Trezise et al.
