The Epithelium Sodium Channel and Cystic Fibrosis

WebThe two ions that are affected are chloride and sodium. But keep in mind that CFTCR is a chloride channel. So chloride is physically being blocked by this channel not working. And sodium is affected because it has a relationship with chloride, but sodium has its own channel, which is not affected in cystic fibrosis. danty known https://tfcconstruction.net
