Role of inflammatory regulators in neovascularization of diabetic retinopathy

Abstract

Diabetic retinopathy(DR)is one of the common diseases that can lead to blindness, and its complicated pathogenesis has not been elucidated completely at present. Many studies have emerged that chronic inflammation plays a prominent role in the pathogenesis of DR. That many “hot spots”of inflammatory molecules, such as IL-6, IL-1β, TNF-α, and MCP-1,are involved in the part of essential mechanism of disease through complex and intertwined inflammatory pathways in the recently research. Above inflammatory factors and angiogenic factors will promote each other, especially when pathological neovascularization occur, which is greatly increasing in severity of the disease. The article made a general debate about the effect of inflammation in DR, and the relationship between inflammation and neovascularization.
