Role of interleukin-6 in ocular inflammatory diseases / 国际眼科杂志(Guoji Yanke Zazhi)

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.
