IL-6在眼部炎性疾病中的作用

Role of interleukin-6 in ocular inflammatory diseases

摘要:

白细胞介素-6(interleukin-6， IL-6)是由单核细胞、巨噬细胞、T淋巴细胞及其他细胞类型产生的多效性细胞因子，在感染和炎症过程中显著上调，是宿主抵御环境压力(如损伤和感染)的核心细胞因子。异常及持续的IL-6的产生与各种自身免疫及炎症性疾病的发展密切相关。越来越多的研究表明，IL-6在眼结膜、角膜、葡萄膜、视网膜等部位的炎症和血管生成中发挥重要作用。IL-6的阻断可以改善眼部慢性、难治性炎症。本文就IL-6在眼部炎症性疾病中的作用及机制进行综述，以期深入、系统地了解IL-6在眼部炎症性疾病中的作用。

Abstract:

Interleukin-6(IL-6)is a pleiotropic cytokine produced by monocytes, macrophages, T lymphocytes and other cell types. It is significantly up-regulated in the process of infection and inflammation, and is the core cytokine of the host's defense against environmental stresses(such as injury and infection). Abnormal and persistent IL-6 production is closely associated with the development of various autoimmune and inflammatory diseases. A growing number of studies have shown that IL-6 plays a critical role in ocular inflammation and angiogenesis in the conjunctiva, cornea, uvea and retina. Blockade of IL-6 ameliorates chronic and refractory intraocular inflammation. This article aims to review the role as well as the mechanism of IL-6 in ocular inflammatory diseases, attempting to have a deep and systematic understanding of the role of IL-6 in ocular inflammatory diseases.
