中文摘要：

肝纤维化是一种在世界范围内高发病率与高死亡率的疾病,严重威胁人们的生活质量。研究发现,免疫系统的激活与肝纤维化的发生发展关系密切,其中尤以树突状细胞（dendriticcells,DCs）在肝纤维化中的作用最为明显。研究表明,DCs对肝脏免疫功能具有关键调节作用,不仅能够介导肝脏免疫系统的激活和炎症反应的发生,同时对肝纤维化的发生发展进程有重要影响。进一步研究发现,DCs在肝纤维化的不同时期对疾病的作用不同,在疾病的早期及消退期,DCs具有抗肝纤维化的作用;而在疾病的中期,DCs则发挥相反的作用。该文对DCs在肝纤维化中作用的研究进展进行综述,探讨DCs介导调控肝纤维化的内在机制,为肝纤维化后续的科学研究及指导临床提供重要参考。

英文摘要：

Liver fibrosis is a major cause of morbidity and mor- tality worldwide which poses a great threat to public health. Con- siderable evidence suggests that the immune system is closely re- lated to the development of hepatic fibrosis especially the dendrit- ic cells （DCs）. In recent years, many studies have showed that DCs play a key role in regulating the immune function of liver, which not only mediate the activation of the immune system and inflammation reaction in liver, but influence the occurrence and development of liver fibrosis. Further study has found that DCsexert different effects on liver fibrosis at different stages of the disease, and it exerts anti-fibrosis in early stages and recession period, while plays opposite effect in the middle of the disease. This article reviews the research progress of the role of DCs in liver fibrosis and discusses the underlying mechanisms of DCs in regulation of liver fibrosis, which may provide references for bas- ic and chnical studies of liver fibrosis.
