Using a genetic approach, we showed trypsin activity is critical for the severity of both acute and chronic pancreatitis. INTRODUCTION WebAcinar cell injury initiates an inflammatory response, which runs in parallel to trypsinogen activation. Studies in trypsinogen knockout models show persistent inflammatory damage, suggesting a secondary mediator of pancreatitis. NF-κB is currently the most described inflammatory mediator active in early pancreatitis [37,38,39,40]. WebHuman chymotrypsin C (CTRC) plays a protective role in the pancreas by mitigating premature trypsinogen activation through degradation.
