Indeed, recent studies have identified luminal pH as an important arbiter of … WebBackground: To determine in vivo effects of CFTR modulators on mutation S945L. Methods: We measured effects of CFTR modulators on CFTR-dependent sweating ('C-sweat') in two pancreatic sufficient cystic fibrosis (CF) subjects. S1 (S945L/G542X) took ivacaftor and S2 (S945L/F508del) took ivacaftor+tezacaftor.
WebOct 21, 2016 · The eccrine sweat gland is a near-ideal organ for assessing the function of CFTR—the anion channel that causes cystic fibrosis (CF) when absent or defective . Sweat is secreted by several million simple, tubular glands that express CFTR in both the absorptive duct and secretory coil. WebMost significantly, g (ENaC) was dramatically reduced, not increased, in CF as compared to non-CF sweat ducts. These results showed that lack of CFTR in the plasma membranes …
