Natural Disruption of Group 2 Phospholipase A2Gene Protects Against Choline-deficient Ethionine-supplemented Diet-induced Acute Pancreatitis and Lung Injury

Group 2 phospholipase A2 (PLA2) plays an important role in the pathogenesis of multiple organ failure associated with acute pancreatitis. C57 BL/6J mice are natural group 2 PLA2 knockout mice lacking group 2 PLA2 mRNA. To clarify the role of group 2 PLA2 in the exacerbation of acute pancreatitis, we studied the biologic and histologic alterations in choline-deficient and ethionine-supplemented (CDE) diet-induced pancreatitis in group 2 PLA2-deficient C57 BL/6J mice and compared them with those in wild-type mice.
