RAGE Mediates a Novel Proinflammatory Axis A Central Cell Surface Receptor for S100/Calgranulin Polypeptides
نویسندگان
چکیده
S100/calgranulin polypeptides are present at sites of inflammation, likely released by inflammatory cells targeted to such loci by a range of environmental cues. We report here that receptor for AGE (RAGE) is a central cell surface receptor for EN-RAGE (extracellular newly identified RAGE-binding protein) and related members of the S100/calgranulin superfamily. Interaction of EN-RAGEs with cellular RAGE on endothelium, mononuclear phagocytes, and lymphocytes triggers cellular activation, with generation of key proinflammatory mediators. Blockade of EN-RAGE/RAGE quenches delayed-type hypersensitivity and inflammatory colitis in murine models by arresting activation of central signaling pathways and expression of inflammatory gene mediators. These data highlight a novel paradigm in inflammation and identify roles for EN-RAGEs and RAGE in chronic cellular activation and tissue injury.

Receptor for age (RAGE) is a gene within the major histocompatibility class III region: implications for host response mechanisms in homeostasis and chronic disease.
Receptor for AGE (RAGE), a member of the immunoglobulin superfamily, was first identified as a specific cell surface interaction site for Advanced Glycation Endproducts, or AGEs. AGEs, the products of nonenzymatic glycation/oxidation of proteins/lipids, accumulate in natural aging and disorders such as diabetes, renal failure and amyloidoses. Interaction of AGEs with RAGE has been linked to chr...
متن کاملRAGE Signaling in Cell Adhesion and Inflammation
The receptor for advanced glycation endproducts (RAGE) has been shown to play an important role in aging, neurodegeneration, diabetes, and inflammation. RAGE is a transmembrane receptor of the immunoglobuline superfamily, which recognizes a variety of ligands such as AGEs (advanced glycation endproducts), members of the S100/calgranulin family of proinflammatory mediators, ß-sheet-fibrills, HMG...
متن کاملS100A12 and the S100/Calgranulins: Emerging Biomarkers for Atherosclerosis and Possibly Therapeutic Targets.
Atherosclerosis is mediated by local and systematic inflammation. The multiligand receptor for advanced glycation end products (RAGE) has been studied in animals and humans and is an important mediator of inflammation and atherosclerosis. This review focuses on S100/calgranulin proteins (S100A8, S100A9, and S100A12) and their receptor RAGE in mediating vascular inflammation. Mice lack the gene ...
متن کاملChronic sustained inflammation links to left ventricular hypertrophy and aortic valve sclerosis: a new link between S100/RAGE and FGF23.
BACKGROUND Cardiovascular disease including left ventricular hypertrophy, diastolic dysfunction and ectopic valvular calcification are common in patients with chronic kidney disease (CKD). Both S100A12 and fibroblast growth factor 23 (FGF23) have been identified as biomarkers of cardiovascular morbidity and mortality in patients with CKD. We tested the hypothesis that human S100/calgranulin wou...

The multiligand receptors that form the focus of this Perspective series have expectedly diverse functions, often conforming to potential gaps in the host response to invading pathogens that are not effectively manned by adaptive immunity. For example, the macrophage scavenger receptor (type A) interacts with bacterial cell walls and enhances clearance of Gramnegative bacteria from the circulat...
