RAGE Ligand Upregulation of VEGF Secretion in ARPE-19 Cells

Abstract

Immobilized or oligomerized ligands for RAGE induce RPE cells to increase VEGF secretion. NF-kappaB plays a central role in RAGE-dependent RPE secretion of VEGF. In AMD, activation of the RAGE axis in RPE cells may contribute to upregulation of VEGF, potentially inciting or propagating neovascular macular disease.
