Revascularization of ischemic retinal tissue and screening method thereof

摘要

The present invention provides a treatment for promoting beneficial physiological revascularization of ischemic retinal tissue. The treatment comprises administering to a mammal suffering from a retinal vascular ischemia a therapeutically effective amount of an angiostatic fragment of tryptophanyl-tRNA synthetase (TrpRS), thereby simultaneously inhibiting pathological neovascularization while promoting beneficial physiological revascularization of damaged areas of the retina. In a preferred embodiment, the angiostatic fragment of TrpRS is T2-TrpRS or T2-TrpRS-GD. Preferably, the mammal is a human patient suffering from retinal ischemia.
