C57Bl6J retina lysates


ABSTRACT: Diabetic retinopathy (DR) is one of the main causes of blindness in working age populations in industrialized countries. It is estimated that close to 100 million individuals worldwide suffer from DR. Regrettably, relatively little is known of the cellular processes at play during late stages of the disease, especially concerning diabetic macular edema (DME). Streptozotocin-induced diabetic retinopathy (STZ) allows to reproduce experimentally in the mouse retina the retina vascular leakage and neuroegeneration features observed in human pathological retina with non-proliferative DR. Using agnostic and orthogonal approaches, in our work we demonstrate that in contrast to healthy retina, the STZ diabetic retina engages pathways of cell cycle arrest, resulting in cellular senescence. These findings combined with further pharmacological approaches provide mechanistic evidence supporting that targeting selectively senescent vessels in DR represents a potential treatment for high vascular permeability in DME.
