摘要:
肠道菌群是一个复杂且多样化的生态系统,各类菌群之间存在着特定的共生关系,同时,胃肠道与肝脏之间通过门脉循环形成紧密的解剖、功能双向联通网络,进而相互维持稳态。“肠-肝轴”理论在肝脏疾病的发病机制中具有深远意义,越来越多的研究证实肠道菌群与肝脏疾病密切相关,它们可以通过多种方式和通路影响肝脏病理生理学进程。在病理情况下,由于各种原因导致菌群生态失调、功能紊乱时,肠道菌群则会与宿主免疫系统及其他类型细胞产生多种相互作用,进而导致肝脏脂肪变性、炎症、纤维化,继而引发各类肝脏疾病,如酒精性肝病、非酒精性脂肪性肝病、原发性硬化性胆管炎、急性肝衰竭、肝细胞癌等。 越来越多关于益生元/益生菌改善肝病的报道逐渐打开了以菌治病的新世界。因此,肠道微生物群落里隐藏的潜在信息和价值是无穷的。为了更加全面地探究各类复杂疾病的病理生理机制,我们仍需继续深入了解某些特定的肠道微生物在参与肝脏损伤进程、改善疾病进程方面的重要作用,为找寻科学有效的临床治疗方法奠定基础。现有综述报道很少同时阐述肠道菌群与急性及慢性肝脏疾病的密切关系。本文以此为出发点,探讨近年来关于急性及慢性肝损伤的研究成果,并得出结论:肝脏的解剖结构促成其与肠道菌群形成彼此沟通的紧密网络,而肠道菌群则是调节肝脏生理、病理功能的重要参与者。
Abstract:
Gut microbiota constitute a complicated but manifold ecosystem, in which specific symbiotic relationships are formed among various bacteria. To maintain a steady state, the gastrointestinal tract and the liver form a close anatomical and functional two-way, interconnected network through the portal circulation. "Gut-liver axis" plays a key role in the pathogenesis of liver diseases. Accumulating evidence indicates that gut microbiota can influence the liver pathophysiology directly or indirectly via a variety of signal pathways. In a pathological state where an ecological imbalance occurs at the compositional and functional levels, gut microbes would interact with the host immune system and other type of cells to cause liver steatosis, inflammation and fibrosis, which in turn give rise to the development of such liver diseases as alcoholic liver disease, nonalcoholic fatty liver disease, primary sclerosing cholangitis, and acute liver failure, to name a few. Studies have shown that microorganisms, such as prebiotics and probiotics, can improve the prognosis of certain diseases, which open a new era of treating liver diseases with bacteria. There are many unknowns and hidden values in the gut microbiome. To explore the pathophysiological mechanism of various complex diseases and develop scientific and effective clinical treatment strategies, efforts should be made to obtain insights into how certain intestinal microbiota participates in the occurrence and progression of liver diseases. As the connection between gut microbiota and liver diseases at both the acute and chronic phases was not elaborated in previously published review articles, herein we discuss the association between gut microbiota and both acute and chronic liver injury. The anatomical structure of the liver enables it to form a close network with the gut microbiota, which is an important mediator in the regulation of the hepatic physiological and pathological functions.
