چکیده

Clearance of apoptotic cells is necessary for tissue development, homeostasis and resolution of inflammation. The uptake of apoptotic cells is initiated by an 'eat-me' signal, such as phosphatidylserine, on the cell surface and phagocytes recognize the signal by using specific receptors. In this study, we show that the soluble form of the receptor for advanced glycation end products (RAGE) binds to phosphatidylserine as well as to the apoptotic thymocytes. RAGE-deficient (Rage(-/-)) alveolar macrophages showed impaired phagocytosis of apoptotic thymocytes and defective clearance of apoptotic neutrophils in Rage(-/-) mice. Our results indicate that RAGE functions as a phosphatidylserine receptor and assists in the clearance of apoptotic cells.

Phosphatidylserine receptors: what is the new RAGE?

the recognition of apoptotic cells by phagocytes is a complex, yet highly orchestrated event. Many receptors have been identified that recognize phosphatidylserine (pS; Fig 1)—which is exposed on early apoptotic cells—leading to downstream signalling and apoptotic cell engulfment. in this issue of EMBo reports, the receptor for advanced glycation endproducts (ragE) is described as a new pS rece...

Receptor for advanced glycation end products involved in circulating endothelial cells release from human coronary endothelial cells induced by C-reactive protein

Objective(s): This study was designed to investigate the effect of receptor for advanced glycation end products (RAGE), S100A12 and C-reactive protein (CRP) on the release of circulating endothelial cells (CECs) from human coronary artery endothelial cells (HCAECs). Materials and Methods: HCAECs were cultured in increasing concentration of CRP (0, 12.5, 25, 50μg/ml) or S100A12 protein (0, 4, 1...

Advanced Glycation End-Products and Their Receptor-Mediated Roles: Inflammation and Oxidative Stress

Glycation is a protein modification, which results in a change in a protein structure. Glycation is believed to be the etiology of various age-related diseases such as diabetes mellitus and Alz-heimer’s disease (AD). Activation of microglia and resident macrophages in the brain by glycated proteins with subsequent oxidative stress and cytokine release may be an important factor in the progressi...

Assessment of Oral Glycine and Lysine Therapy on Receptor for Advanced Glycation End Products and Transforming Growth Factor Beta Expression in the Kidney of Streptozotocin-Induced Diabetic Rats in Comparison with Normal Rats

Background & Aims: Today, diabetic nephropathy is considered to be one of the most common causes of end stage renal disease. Uncontrolled hyperglycemia, and consequently, production of advanced glycation end products activate pathways which play key roles in diabetic nephropathy. Among these pathways, high expression of receptor for advanced glycation end products (RAGE) and transforming growth...
