Functional interaction of CFTR and ENaC in sweat glands

WebThe cystic fibrosis transmembrane conductance regulator (CFTR) plays a significant role in transepithelial salt absorption as well as secretion by a number of epithelial tissues … WebThe CFTR gene is a protein that functions as a chloride channel. A chloride channel helps maintain the proper balance of salt and water within a cell. A mutation in CFTR causes a dysfunction of the salt and water balance. This causes dehydration of the secretions (thick mucous) and excessive loss of salt in sweat. heat and glow remote controlWebMar 24, 2024 · The CFTR protein is located in every organ of the body that makes mucus, including the lungs, liver, pancreas, and intestines, as well as sweat glands. The CFTR protein has also been found in other cells in the body, such as cells of the heart and the immune system.

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. Cystic fibrosis is caused by defects in a protein found in many tissues, including the airways and the sweat glands. As a result, these tissues do not work properly. Sweat testing makes use of the fact that cystic fibrosis patients have defective sweat glands. Sweat glands produce sweat through a well understood process of secretion and reabsorption of sodium chloride (salt). Secretion entails the movement of salt and water from sweat gland cells i…

WebApr 12, 2024 · The sweat glands of people with cystic fibrosis appear to be histologically normal, however, they have saltier sweat due to overproduction of sodium and chloride. This issue is related to a protein … WebSweat glands produce sweat through a well understood process of secretion and reabsorption of sodium chloride (salt). Secretion entails the movement of salt and water from sweat gland cells into the sweat duct. ... Unlike CFTR chloride channels, sodium channels behave perfectly normally in cystic fibrosis. However, in order for the secretion to ...

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. The CFTR gene is on at lower levels in cells that line certain reproductive organs in both men and women, and in sweat glands in the skin. WebOct 6, 2016 · Role of CFTR in sweat gland physiology. The human eccrine (or atrichal) sweat gland helps to maintain whole body temperature via the production of sweat in …

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 ...
