VIOLATIONS OF CYTOKINE REGULATION IN THE PATHOGENESIS OF PROLIFERATIVE DIABETIC RETINOPATHY
Purpose. To study the content of the transforming growth factorbeta 2 (TGF-β2), vascular endothelial growth factor (VEGF), pigment epithelium factor (PEDF) and several cytokines in the vitreous body in patients with proliferative diabetic retinopathy (PDR), to evaluate an activity of proliferative a...

description | Purpose. To study the content of the transforming growth factorbeta 2 (TGF-β2), vascular endothelial growth factor (VEGF), pigment epithelium factor (PEDF) and several cytokines in the vitreous body in patients with proliferative diabetic retinopathy (PDR), to evaluate an activity of proliferative and immune-inflammatory process.Material and methods. Vitreous samples of patients with proliferative diabetic retinopathy and retinal detachment traction were examined as well as patients with traction retinal detachment without the PDR (control). Concentration of TGF- β 2, VEGF, PEDF MCP-1, interleukin 4, 6, 8, 10, 17A was determined by the ELISA method.Results. A reliable increase in the concentrations of pro-inflammatory cytokines IL-17A, IL-8, IL-6, MCP-1, anti-inflammatory cytokine IL-4, transforming growth factor-beta 2, vascular endothelial growth factor, factor of pigment epithelium and monocyte chematacticprotein-1 was detected in the vitreous of PDR patients.Conclusions. The findings indicate the existence of cytokine regulation violations in the PDR pathogenesis. It was noted that the activity of local inflammatory and proliferative processes was determined in the PDR pathogenesis. The revealed correlative relationships indicate interdependence of these processes. The detected reliable increase of monocyte chemotactic protein-1 in the vitreous of PDR patients, allows to make an assumption about its participation in the mechanisms of vascular proliferation. |
