Role of naringenin in the prevention and treatment of autoimmune hepatitis and its molecular mechanism
-
摘要: 自身免疫性肝炎(AIH)是一种由T淋巴细胞介导的慢性炎症性肝病,若未及时干预可进展为肝硬化甚至肝衰竭。天然黄酮类化合物柚皮素(NAR)具有重塑免疫稳态、靶向抑制炎症通路、抗氧化、调节肝细胞代谢与凋亡、改善线粒体功能及调节肠道菌群等多重机制,在AIH防治中展现出潜在价值。但柚皮素自身存在生物利用度低、肝靶向递送效率不足等问题,使其临床转化与应用受到制约。本文系统综述NAR防治AIH的作用机制,深入探讨其在AIH防治中可能涉及的信号通路,并分析当前其转化应用存在的挑战及未来的研究方向,以期为NAR在AIH防治领域的进一步研究和临床应用提供理论参考。Abstract: Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease mediated by T lymphocytes, and it can progress to liver cirrhosis or even liver failure without timely intervention. As a natural flavonoid compound, naringenin (NAR) shows a potential value in the prevention and treatment of AIH through multiple mechanisms such as remodeling immune homeostasis, targeted inhibition of inflammatory pathways, antioxidation, regulating hepatocyte metabolism and apoptosis, improving mitochondrial function, and regulating intestinal flora. However, the clinical translation and application of NAR is limited by issues such as low bioavailability and insufficient efficiency of liver-targeted delivery. This article systematically reviews the mechanism of action of NAR in the prevention and treatment of AIH, explores the potential signaling pathways involved in this process, and analyzes existing challenges in its translation and application and future research directions, so as to provide a reference for further research on NAR and its application in the prevention and treatment of AIH.
