|Abstract||Treatment of patients with acute pancreatitis has greatly improved due to a better understanding of the pathophysiology of the disease. This pathophysiology includes the activation and release of pancreatic enzymes in the interstitium, the autodigestion of the pancreas, and a multiple organ dysfunction after their release into the systemic circulation. Moreover, significant evidence exists that synthesis and release of proinflammatory cytokines and chemokines are also responsible for the local injury and systemic dispersion of the inflammation. The use of knockout mice devoid of active pro- or anti-inflammatory mediators allows examination of the effects of a specific cytokine without any drawbacks induced by pharmacological manipulations. The results obtained from these genetically modified mice show that numerous mediators have a major role in the pathophysiology of acute pancreatitis. They also clearly demonstrate that a single genetic deletion cannot completely prevent the occurrence of pancreatic or distant organ injury. However, the fact that the immune system is characterized by redundancies of ligands and receptors complicates the full understanding of each report. The utility of such experimental models might have limitations, and a full extrapolation of experimental data from genetically modified mice to humans must be done with caution.|
