RAGE, the receptor for advanced glycation endproducts (AGEs), is a multiligand signal transduction receptor of the immunoglobulin superfamily of cell surface molecules that has been implicated in the pathogenesis of diabetic complications, neurodegenerative diseases, inflammatory disorders, and cancer. These diverse biologic disorders reflect the multiplicity of ligands capable of cellular interaction via RAGE that include, in addition to AGEs, amyloid-beta (Aβ) peptide, the S100/calgranulin family of proinflammatory cytokines, and amphoterin, a member of the High Mobility Group Box (HMGB) DNA-binding proteins. In the retina, RAGE expression is present in neural cells, the vasculature, and RPE cells, and it has also been detected in pathologic cellular retinal responses including epiretinal and neovascular membrane formation. Ligands for RAGE, in particular AGEs, have emerged as relevant to the pathogenesis of diabetic retinopathy and age-related macular disease. While the understanding of RAGE and its role in retinal dysfunction with aging, diabetes mellitus, and/or activation of pro-inflammatory pathways is less complete compared to other organ systems, increasing evidence indicates that RAGE can initiate and sustain significant cellular perturbations in the inner and outer retina. For these reasons, antagonism of RAGE interactions with its ligands may be a worthwhile therapeutic target in such seemingly disparate, visually threatening retinal diseases as diabetic retinopathy, age-related macular degeneration, and proliferative vitreoretinopathy.
