WebApr 18, 2024 · The effect of a constant loss of C-sweat increases proportionally as the C-sweat rate slows, eventually exceeding the C-sweat rate in glands with low residual CFTR function. We previously estimated the constant loss to be 0.023 nl·min -1 ·gl -1 or ~2% of the average WT C-sweat value [ 14 ], and used this estimate to explain the inability of ... WebThe CFTR gene is switched off in most cell types. It is on at high levels in cells that line the lungs and digestive organs, especially the gallbladder, pancreas, and intestines.

WebOct 10, 2024 · CFTR is a transmembrane protein that functions as part of a cAMP-regulated chloride ion channel; in normal sweat glands, the ductal epithelium reabsorbs sodium and chloride ions in response to aldosterone so that sweat is hypotonic.

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. WebIn sweat glands, CFTR is responsible for the reabsorption of chloride in the sweat duct. Sodium ions follow passively through ENaC as a result of the electrochemical gradient caused by chloride flow. This reduces salt and water loss. In the absence of chloride flow in cystic fibrosis, sodium ions do not flow through ENaC, leading to greater ...
