Endothelial Progenitor Cells in Diabetic Retinopathy
Diabetic retinopathy (DR) is a leading cause of visual impairment worldwide. Patients with DR may irreversibly lose sight as a result of the development of diabetic macular edema (DME) and/or proliferative diabetic retinopathy (PDR); retinal blood vessel dysfunction and degeneration plays an essential role in their pathogenesis. Although new treatments have been recently introduced for DME, inc...
متن کاملEndothelial fenestrae in proliferative diabetic retinopathy.
The ultrastructure of old neovascular preretinal membranes was examined in both eyes of a patient with proliferative diabetic retinopathy treated in one eye with photocoagulation. Membranes in both eyes consisted of a matrix rich in mature collagen surrounding viable new vessels and "ghost vessels." Viable vessels of different calibers frequently showed endothelial fenestrae bridged by diaphrag...
متن کاملInvolvement of RhoA/ROCK1 signaling pathway in hyperglycemia-induced microvascular endothelial dysfunction in diabetic retinopathy.
Diabetic retinopathy (DR) is a well-known serious complication of diabetes mellitus (DM), and can eventually advance to end-stage blindness. In the early stage of DR, endothelial cell barrier disorganized primarily and tight junction (TJ) protein composition transformed subsequently. The small GTPase RhoA and its downstream effector Rho-associated coiled-coil containing protein kinase 1 (ROCK1)...
متن کاملDiabetic Retinopathy and Endothelial Dysfunction in Patients with Type 2 Diabetes Mellitus
BACKGROUND We investigated the relationship between endothelial dysfunction and diabetic retinopathy (DR) in patients with type 2 diabetes. METHODS We used a cross-sectional design to examine 167 patients with type 2 diabetes mellitus. All patients underwent biochemical and ophthalmological examination. We assessed endothelial dysfunction by a flow-mediated vasodilation method of the brachial...
متن کاملThe role of inflammation and endothelial dysfunction in the pathogenesis of diabetic retinopathy.
The pathogenesis of diabetic retinopathy (DR) is insufficiently understood and presumed to possibly involve inflammation and endothelial dysfunction. The aim of the study was to investigate the relationship between inflammation markers, other markers of endothelial dysfunction and anthropometric parameters and their association with DR in patients with type 2 diabetes, divided into three groups...
