| Summary |
Schemic retinopathies such as diabetic retinopathy (DR) and retinopathy of prematurity (ROP), are the main causes of blindness in working age and pediatric populations in industrialized countries. It is estimated that close to 100 million individuals worldwide suffer from DR and 15 million preterm infants born each year are predisposed to ROP. Regrettably, relatively little is known of the cellular processes at play during late stages of pathological angiogenesis in these diseases and consequently current standards of care target all neovascularization. Oxygen-induced retinopathy (OIR) allows to reproduce experimentally in the mouse retina the pathological features observed in human pathological retina such as ischemic avascular regions as well as epi-retinal neovascularization. Using agnostic and orthogonal approaches, in our work we demonstrate that in contrast to healthy blood vessels, pathological vessels engage pathways of cell cycle arrest, resulting in cellular senescence. These findings combined with further genetic and pharmacological approaches provide mechanistic evidence supporting that targeting selectively senescent vessels in DR represents a potential treatment for neovascular retinal disease.
