A study of two eye lens crystallins. Chibber R, Molinatti PA, Rosatto N, Lambourne B, Kohner EM. During long standing hyperglycaemic state in diabetes mellitus, glucose forms covalent adducts with the plasma proteins through a non-enzymatic process known as glycation. The potential clinical application of RAGE blockade include the decreased progression of diabetic retinopathy as upregulation of RAGE leads to pro-inflammatory responses by retinal Mller glia cells [83]. This excessive cross-linking disturbs the flexibility characteristic of matrix proteins, making them rigid. Advanced Glycation End Products and Diabetes Mellitus: Mechanisms and Perspectives Persistent hyperglycemic state in type 2 diabetes mellitus leads to the initiation and progression of non-enzymatic glycation reaction with proteins and lipids and nucleic acids. Moreover, AGEs can also act as cross-linkers between proteins, resulting in the production of proteinase-resistant aggregates [24]. The AGEs/RAGE mediated signaling causes enhanced oxidative stress and increased inflammation in pancreatic beta cells. 2006; Mulder et al. The maillard reaction in eye diseases. Collagen also provides the framework for the most of the parenchymal organs, either in its fibrous form or organized in basement membrane. Forbes JM, Cooper ME, Oldfield MD, Thomas MC. Collagen is a major component of the ECM and is a prominent target of non-enzymatic glycation [53]. Hyperglycemia elicits several pathways related to the etiopathogenesis of cardiovascular disease (CVD), including the generation of advanced glycation end products (AGEs). 2001;44:S14S21. Mechanistic aspects concerning the recognition of AGEs by the . Fibrin(ogen) may be an important target for methylglyoxal-derived AGE modification in elastic arteries of humans. Maillard reaction is the classical pathway of advanced glycation, AGEs/RAGE-induced pancreatic beta cell toxicity., AGEs/RAGE-induced pancreatic beta cell toxicity. Glycation of immunoglobulins has been shown to cause major structural disruptions resulting in their functional disability [48]. Glycation reaction leads to the generation of a heterogeneous group of chemical moieties known as advanced glycated end products (AGEs), which play a central role in the pathophysiology of diabetic complications. Address correspondence and reprint requests to Amy G. Huebschmann, MD, Assistant Professor of Medicine, University of Colorado Denver and Health Sciences Center, P.O. This AGE-induced pericytes death has been associated to signaling through RAGE [100], induction of oxidative stress, inhibition of integrin-mediated protein kinase B/Akt phosphorylation, and reduced survival signaling by PDGF [101].

HHS Vulnerability Disclosure, Help It is demonstrated that AGEs could induce podocyte DNA damage and detachment partly via stimulation of the angiotensin II (Ang II) type 1 receptor (AT1R) [128]. AGEs/RAGE axis and diabetic complications. About 50% of plasma proteins are protein albumin, which is the major contributor to osmotic pressure of plasma and assist in the transport of lipids and steroid hormones. Glycation of proteins interferes with their normal functions by disrupting molecular conformation, altering enzymatic activity, reducing degradation capacity, and interfering with receptor recognition [16]. Diabetic nephropathy progresses to end-stage renal disease via a number of stages including normal albuminuria, incipient diabetic nephropathy, micro albuminuria and finally end-stage renal disease [120,121].

Pageon and his co-workers created a model of reconstructed skin modified by glycation of the collagen used to fabricate the dermal compartment and demonstrated the key role of glycation in skin aging [60]. Advanced glycosylated end products and hyperglycemia in the pathogenesis of diabetic complications Protein alteration resulting from a nonenzymatic reaction between ambient glucose and primary amino groups on proteins to form glycated residues called Amadori products is termed the Maillard reaction.

Austin GE, Mullins RH, Morin LG. Action of metformin therapy against advanced glycation, oxidative stress and inflammation in type 2 diabetes patients: 3 months follow-up study. Uptake of extracellular glucose is regulated by the transmembrane glucose gradient and the activity of glucose transporters in the cardiomyocyte plasma membrane. Aminoguanidine is shown to prevent cardiac hypertrophy and arterial stiffening in experimental animal model of diabetic cardiomyopathy [162]. There is also enhanced expression of adhesion molecules including vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1), (Fig. It is anticipated that interactions between AGEs and RAGE facilitate endoneural vascular dysfunction, leading to microangiopathy in the peripheral nerve [150]. Rodrigues B, Cam MC, Kong J, Goyal RK, McNeill JH. Bai P, Phua K, Hardt T, Cernadas M, Brodsky B. Glycation alters collagen fibril organization. In the lens AGEs induce irreversible changes in structural proteins, which lead to lens protein aggregation and formation of high-molecular-weight aggregates that scatter light and impede vision [90]. These pathologic processes may affect every cell component in peripheral nervous tissues. It is shown that the binding of AGEs with RAGE in the endothelial cell activates transcription factors of NF-B and activator protein-1 (AP-1) to increase the, expression of vascular cell adhesion molecule-1 and cytokines such as tumor necrosis factor and interleukin-6 [72].

It is demonstrated that protein glycation may be involved in cataract development, by altering protein structure, particularly amino acid composition, and formation of fluorophores through a Maillard reaction [117]. This upregulation of RAGE may cause an increase in transduction signals following stimulation by AGEs and this may exacerbate loss of pericytes in diabetic retinopathy. Crosslinking of proteins by AGE in the vessel wall increases vascular stiffness and modification of ECM proteins decreases pericyte adherence [94]. Exposing the isolated cardiac myocytes to elevated glucose alone results in impaired contractility and calcium handling [173].

Advanced glycation end products and their receptors in serum of In the Polyol pathway, an excessive amount of glucose is reduced to sorbitol by the enzyme aldol reductase, which is then converted to fructose by sorbitol dehydrogenase. Advanced glycation end products attenuate cellular insulin sensitivity by increasing the generation of intracellular reactive oxygen species in adipocytes. Unoki H, Bujo H, Yamagishi S, Takeuchi M, Imaizumi T, Saito Y. Disclaimer. AGEs elicit a wide range of cell-mediated responses leading to vascular dysfunction, matrix expansion and athero- and glomerulosclerosis. Cross-linked and glycated extracellular proteins (collagen) contribute to aging and diabetes. Halliwell B. Furthermore, humans are also exposed to exogenous AGEs which are ingested with food. AGEs form intra- and extracellular cross linking not only with proteins, but with some other endogenous key molecules including lipids and nucleic acids to contribute in the development of diabetic complications. The adverse effects of persistently elevated plasma glucose levels on the different body parts vary according to the cell types. Advanced glycosylation end product (AGE) levels are elevated in diabetic patients and may contribute to the excessive cardiovascular disease in this population, promoting oxidant stress and chronic vascular inflammation. Glycation of collagen and laminin alters the electric charge of the basement membrane to increase the permeability of blood vessels, and cause thickening of the basement membrane. Exposure of retinal cells to AGEs causes upregulation of the potent mitogen, vascular endothelial cell growth factor (VEGF) by increasing VEGF gene expression.
