Interleukin-22 (IL-22) is a member of IL-10 family cytokines that is produced by many different types of lymphocytes including both those of the innate and adaptive immune systems. This includes activated T cells, most notably Th17 and Th22 cells, and NK cells, γδ T cells, LTi cells and LTi-like cells. IL-22 mediates its effects via the IL-22-IL-22R complex and subsequent Janus kinase-signal transducer and activators of transcription (JAK-STAT) signaling pathway. Recently accumulated evidence has indicated that IL-22 also plays an important role in the pathogenesis of many autoimmune diseases. In this review, we discuss the recent findings and advancement of the role for IL-22 in several autoimmune diseases, such as psoriasis, rheumatoid arthritis (RA), hepatitis, graft versus host disease (GHVD) and allergic diseases, implicating that target IL-22 may have a therapeutic potential in those autoimmune diseases.
白细胞介素-22(IL-22)是白细胞介素 10 家族细胞因子的一员,由许多不同类型的淋巴细胞产生,包括先天和适应性免疫系统的细胞。这包括激活的 T 细胞,特别是 Th17 和 Th22 细胞,以及 NK 细胞、γδ T 细胞、LTi 细胞和 LTi 样细胞。IL-22 通过 IL-22-IL-22R 复合物和随后的 Janus 激酶信号转导和转录激活因子(JAK-STAT)信号通路发挥其作用。最近积累的证据表明,IL-22 在许多自身免疫性疾病的发病机制中也起着重要作用。在这篇综述中,我们讨论了 IL-22 在几种自身免疫性疾病中的作用的最新发现和进展,如银屑病、类风湿关节炎(RA)、肝炎、移植物抗宿主病(GHVD)和过敏性疾病,表明靶向 IL-22 可能具有治疗那些自身免疫性疾病的潜力。
