Multiple roles for TGFβ receptor type II in regulating the pancreatic response in acute pancreatitis.

In their recent publication in Journal of Pathology, Grabliauskaite and Sapanora and their colleagues in Zurich use a conditional ablation of the TGFβ type II receptor (TBRII) to analyse its specific role in pancreatic epithelial cells in response to a caerulein-induced model of acute pancreatitis. These experiments help to clarify some confusion that has existed in the literature stemming from the use of a dominant-negative transgenic TBRII mouse. The results point to a central role for TBRII in acinar cells in mitigating the overall response of the pancreas to the damage and inflammation of acute pancreatitis.
