Liver fibrosis is the common response to chronic liver injury, ultimately leading to cirrhosis and its complications: portal hypertension, liver failure, hepatic encephalopathy, and hepatocellular carcinoma and others. Efficient and well-tolerated antifibrotic drugs are still lacking, and current treatment of hepatic fibrosis is limited to withdrawal of the noxious agent. Efforts over the past decade have mainly focused on fibrogenic cells generating the scarring response, although promising data on inhibition of parenchymal injury or reduction of liver inflammation have also been obtained. A large number of approaches have been validated in culture studies and in animal models, and several clinical trials are underway or anticipated for a growing number of molecules. This review highlight recent advances in the molecular mechanisms of liver fibrosis and discusses mechanistically based strategies that have recently emerged.
肝纤维化是慢性肝损伤的常见反应,最终会导致肝硬化及其并发症,如门静脉高压、肝衰竭、肝性脑病和肝细胞癌等。目前仍缺乏高效且耐受性良好的抗纤维化药物,而当前肝纤维化的治疗仅限于停用有害物质。在过去十年中,研究主要集中在产生瘢痕反应的纤维化细胞上,不过也获得了关于抑制实质损伤或减轻肝脏炎症的有前景的数据。大量方法已在细胞培养研究和动物模型中得到验证,并且针对越来越多的分子正在进行或预计将开展多项临床试验。本综述重点介绍了肝纤维化分子机制的最新进展,并讨论了最近出现的基于机制的策略。
