| Outline of Final Research Achievements |
Ischemic retinopathy such as proliferative diabetic retinopathy causes blindness through the hemorrhage in immature vessels formed by the progression of the diseases. Therefore, there is a need to identify mechanisms of vascular maturation, which is the stage of mural cell adhesion to endothelial cells for stabilization of blood vessels, for the treatment of ischemic retinopathy. In this study, we revealed that inhibition of apelin expression induced the vessel maturation in the retina of an ischemic retinopathy model mouse. Moreover, we demonstrated that apelin blockade in cultured-endothelial cells led to increase of monocyte chemoattractant protein-1 (MCP-1) which is a mural cell recruitment factor.
