RAGE, the receptor for advanced glycation endproducts is a 35kD transmembrane receptor of the immunoglobulin super family which was first characterized in 1992 by Neeper et al.. Its name comes from its ability to bind advanced glycation endproducts (AGE), a heterogeneous group of non-enzymatically altered proteins. Besides AGEs, RAGE is also able to bind other ligands and is thus often referred to as a pattern recognition receptor.The interaction between RAGE and its ligands is thought to result in pro-inflammatory gene activation. Due to an enhanced level of RAGE ligands in diabetes or other chronic disorders, this receptor is hypothesised to have a causative effect in a range of inflammatory diseases such as diabetic complications, Alzheimer's disease and even some tumors.
