BACKGROUND The receptor for advanced glycation end products (RAGE) is implicated in the development and progression of atherosclerosis. We tested the hypothesis that (99m)Tc-labeled anti-RAGE F(ab')(2) can be used as a noninvasive tool to image atherosclerotic lesions in apolipoprotein E-deficient (apoE(-/-)) mice. METHODS AND RESULTS A sequence in the V-type Ig extracellular domain of RAGE w...

The receptor for advanced glycation end products (RAGE) is a pattern-recognition receptor involved in neurodegenerative and inflammatory disorders. RAGE induces cellular signaling upon binding to a variety of ligands. Evidence suggests that RAGE up-regulation is involved in quinolinate (QUIN)-induced toxicity. We investigated the QUIN-induced toxic events associated with early noxious responses...

Parkinson's disease (PD) is a common neurodegenerative disorder of unknown pathogenesis characterized by the loss of nigrostriatal dopaminergic neurons. Oxidative stress, microglial activation and inflammatory responses seem to contribute to the pathogenesis. The receptor for advanced glycation endproducts (RAGE) is a multiligand receptor of the immunoglobulin superfamily of cell surface molecu...

Receptors for advanced glycation end-products (RAGE) are multiligand cell surface receptors of the immunoglobin family expressed by epithelium and macrophages, and expression increases following exposure to cigarette smoke extract (CSE). The present study sought to characterize the proinflammatory contributions of RAGE expressed by alveolar macrophages (AMs) following CSE exposure. Acute exposu...

Amphoterin is a protein enhancing process extension and migration in embryonic neurons and in tumor cells through binding to receptor for advanced glycation end products (RAGE), a multiligand transmembrane receptor. S100 proteins, especially S100B, are abundantly expressed in the nervous system and are suggested to function as cytokines with both neurotrophic and neurotoxic effects. However, th...

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...

Lipopolysaccharide (LPS) is known to induce acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Accumulating data suggest the crucial role of RAGE in the pathogenesis of ALI/ARDS. However, the mechanism by which RAGE mediates inflammatory lung injury in the neonates remains elusive. In this study we established LPS-induced ALI model in neonate rats, and investigated the role...

Lung cancer is one of the most common malignancies in the world and one of the leading causes of death from cancer. In the search for molecules that may be involved in lung tumor induction and progression, the receptor of advanced glycation end products (RAGE) comes across as a critical regulator of lung physiology. RAGE is a multiligand receptor that presents a differential expression pattern ...

The receptor for advanced glycation end products (RAGE) and thioredoxin (Trx) play opposing roles in diabetic myocardial ischemia-reperfusion (MI/R) injury. We recently demonstrated nitrative modification of Trx leads to its inactivation and loss of cardioprotection. The present study is to determine the relationship between augmented RAGE expression and diminished Trx activity pertaining to ex...

OBJECTIVES To determine whether baseline plasma levels of the receptor for advanced glycation end products (RAGE), a novel marker of alveolar type I cell injury, are associated with the severity and outcomes of acute lung injury, and whether plasma RAGE levels are affected by lower tidal volume ventilation. DESIGN, SETTING AND PARTICIPANTS Measurement of plasma RAGE levels from 676 subjects e...
