Mitochondrial dysfunction in the pathogenesis of acute pancreatitis

引用

Hepatobiliary & Pancreatic Diseases International 2025年第1期24卷 76-83页

作者： Xia Chen Rui zhong bing Hu Department of Gastroenterology and Hepatology West China HospitalSichuan UniversityChengdu 610041China Department of Gastroenterology Clinical Medical College and The First Affiliated Hospital of Chengdu Medical CollegeChengdu 610500China

The mechanism of cell damage during acute pancreatitis (AP) has not been fully elucidated, and there is still a lack of specific or effective treatments. Increasing evidence has implicated mitochondrial dysfunction as a key event in the pathophysiology of AP. Mitochondrial dysfunction is closely related to calcium (Ca^(2+)) overload, intracellular adenosine triphosphate depletion, mitochondrial permeability transition pore openings, loss of mitochondrial membrane potential, mitophagy damage and inflammatory responses. Mitochondrial dysfunction is an early triggering event in the initiation and development of AP,and this organelle damage may precede the release of inflammatory cytokines, intracellular trypsin activation and vacuole formation of pancreatic acinar cells. This review provides further insight into the role of mitochondria in both physiological and pathophysiological aspects of AP, aiming to improve our understanding of the underlying mechanism which may lead to the development of therapeutic and preventive strategies for AP.
