Role of mitochondrial and lysosomal dysfunction in acute pancreatitis pathogenesis

Abstract

Aim of review. To present data on the role of mitochondrial and lysosomal dysfunction in pathogenesis of acute pancreatitis (AP). Summary. Hyperamilasemia, premature intralobular activation of digestive enzymes, accumulation of large vacuoles in acinar cells, activation of proinflammatory mediators, apoptosis and necrosis of acinar cells are the basic pathomorphological signs of AP. The mitochondrial dysfunction that develops at acute pancreatitis is followed by disorders of ATP synthesis and initiation of processes of apoptosis and necrosis. The lysosomal dysfunction at AP is manifested by autophagy disorders that leads to vacuolation of acinar cells and intralobular trypsin accumulation. Conclusion. At the recent time there is noticeable growth in frequency of acute pancreatitis cases and increase of mortality in patients with pancreatic necrosis. Mitochondrial and lysosomal dysfunction acts as pathogenic basis for AP, leading to energy deprivation of pancreatic cells. Mitochondrial and lysosomal dysfunction initiates processes of apoptosis, necrosis, activation of trypsinogen and vacuolation of acinar cells that this disease. Therefore new studies aimed for therapeutic impact on mitochondrions and lysosomes are required. Key words: acute pancreatitis, dysfunction of organellas, mitochondrion, lysosome, apoptosis, necrosis, autophagy.
