| Outline of Final Research Achievements |
Ant-VEGF therapy has globally become the major modality for the treatment of diabetic macular edema (DME). However, because of its insufficient efficacy, development of new drugs for DME is desired. Here, by utilizing a mouse model of diabetic retinopathy which reproduces retinal edema resulting from loss of pericytes, we observed up-regulation of Angiopoietin-2 (Ang2) in endothelial cells of pericyte-free retinal vessels. Furthermore, intraocular injections of anti-Ang2 blocking antibody suppressed retinal edema even in the absence of pericytes. Given that several pharmaceutical companies have developed a series of anti-Ang2 drugs, anti-Ang2 therapy is expectably feasible for the treatment of DME.
