Pancreatic ductal deletion of Hnf1b disrupts exocrine homeostasis, leads to pancreatitis and facilit...

The exocrine pancreas consists of acinar cells that produce digestive enzymes transported to the intestine through a branched ductal epithelium. Chronic pancreatitis is characterized by progressive inflammation, fibrosis and loss of acinar tissue. These changes of the exocrine tissue are risk factors for pancreatic cancer. The cause of chronic pancreatitis cannot be identified in one-quarter of patients. Here, we investigated how duct dysfunction could contribute to pancreatitis development.
