Research Abstract |
Chronic pancreatitis is a progressive disease of the pancreas. Accumulating evidence suggests that CFTR channel, which is expressed in the apical plasma membrane of pancreatic duct cells, is one of the factors that cause pancreatitis. However, it remains unknown how CFTR dysfunction cause pancreatitis. In chronic pancreatitis, CFTR is largely mislocalized in the cytoplasm of pancreatic duct cells. When CFTR expression was reduced by RNA interference in isolated guinea-pig pancreatic duct cells, pancreatic fluid secretion was remarkably reduce to ~50% of control. These findings indicate that CFTR expression directly regulates the fluid secretion from pancreatic duct cells and therefore CFTR dysfunction is one of the mechanisms to develop chronic pancreatitis.
