Abstract

Acute pancreatitis (AP) is a multifaceted inflammatory disorder stemming from the aberrant activation of trypsin within the pancreas. Despite the contribution of various factors to the pathogenesis of AP, such as trypsin activation, dysregulated increases in cytosolic Ca levels, inflammatory cascade activation, and mitochondrial dysfunction, the precise molecular mechanisms underlying the disease are still not fully understood. Mitophagy, a cellular process that preserves mitochondrial homeostasis under stress, has emerged as a pivotal player in the context of AP. Research suggests that augmenting mitophagy can mitigate pancreatic injury by clearing away malfunctioning mitochondria. Elucidating the role of mitophagy in AP may pave the way for novel therapeutic strategies. This review article aims to synthesize the current research findings on mitophagy in AP and underscore its significance in the clinical management of the disorder.

摘要

急性胰腺炎(AP)是一种多方面的炎症性疾病,源于胰腺内胰蛋白酶的异常激活。尽管各种因素(如胰蛋白酶激活、细胞浆钙离子水平失调增加、炎症级联激活和线粒体功能障碍)都对 AP 的发病机制有贡献,但该疾病的确切分子机制仍未完全阐明。在 AP 的背景下,细胞自噬,一种在应激下维持线粒体动态平衡的细胞过程,已成为一个关键的参与者。研究表明,增强细胞自噬可以通过清除功能失调的线粒体来减轻胰腺损伤。阐明细胞自噬在 AP 中的作用可能为新的治疗策略铺平道路。这篇综述文章旨在综合目前关于 AP 中细胞自噬的研究结果,并强调其在该疾病临床管理中的意义。
