Autoimmune hepatitis is a chronic inflammatory hepatic disorder which may cause liver fibrosis. Appropriate treatment of autoimmune hepatitis is therefore important. Adult stem cells have been investigated as therapies for a variety of disorders in latest years. Hematopoietic stem cells (HSCs) were the first known adult stem cells (ASCs) and can give rise to all of the cell types in the blood and immune system. Originally, HSC transplantation was served as a therapy for hematological malignancies, but more recently researchers have found the treatment to have positive effects in autoimmune diseases such as multiple sclerosis. Mesenchymal stem cells (MSCs) are ASCs which can be extracted from different tissues, such as bone marrow, adipose tissue, umbilical cord, and dental pulp. MSCs interact with several immune response pathways either by direct cell-to-cell interactions or by the secretion of soluble factors. These characteristics make MSCs potentially valuable as a therapy for autoimmune diseases. Both ASC and ASC-derived exosomes have been investigated as a therapy for autoimmune hepatitis. This review aims to summarize studies focused on the effects of ASCs and their products on autoimmune hepatitis.
自身免疫性肝炎是一种慢性炎症性肝脏疾病,可能导致肝纤维化。因此,适当治疗自身免疫性肝炎非常重要。近年来,人们一直在研究成体干细胞作为治疗各种疾病的方法。造血干细胞(HSCs)是最早被发现的成体干细胞(ASCs),可以产生血液和免疫系统中的所有细胞类型。最初,HSC 移植被用作治疗血液系统恶性肿瘤的方法,但最近研究人员发现,这种治疗方法对多发性硬化等自身免疫性疾病有积极的影响。间充质干细胞(MSCs)是一种 ASC,可以从不同的组织中提取,如骨髓、脂肪组织、脐带和牙髓。MSCs 通过直接的细胞间相互作用或分泌可溶性因子与几种免疫反应途径相互作用。这些特性使 MSCs 成为治疗自身免疫性疾病的有价值的工具。ASC 和 ASC 衍生的外泌体都被研究作为治疗自身免疫性肝炎的方法。本综述旨在总结关于 ASCs 及其产物对自身免疫性肝炎影响的研究。
