abstractText | AMD is the most common disease leading to acquired blindness in developed countries. CNV is the foremost cause of AMD and is thought to be induced by regional inflammation as a result of age-related conformational changes of the chorioretinal interface. Here, we show that IL-27, a member of the IL-6/IL-12 cytokine family, has an angiostatic effect and regulates the development of laser-induced experimental CNV in mice. In this model, IL-27 expression increased in the damaged choroid and peaked at the 24 h-time-point. IL-27 neutralization, induced by inoculating an antagonistic antibody into the vitreous cavity, enhanced VEGF production and the extent of CNV. By contrast, the administration of rIL-27 reduced VEGF production and the extent of CNV. Mice deficient in the EBI3, which lack IL-27, also showed more CNV than C57BL/6 mice, and this was reduced by IL-27 supplementation. We additionally investigated the effect of IL-27 on the function of macrophages, which play a critical role in CNV. IL-27 did not affect macrophage migration but inhibited its VEGF production. IL-27 therefore appears to regulate CNV and is a promising candidate target for treating sight-threatening diseases caused by ocular neovascularization. |
