RAGE Inhibitors in Neurodegenerative Diseases. In a 1997 study, diabetic and healthy subjects were given a single meal of egg white (56 gprotein), cooked with or without 100g of fructose; there was a greater than 200-fold increase in AGE immunoreactivity from the meal with fructose.[37]. The aim of the project was to check whether there is a close relationship between the occurrence of diabetes, diabetic complications, atherosclerosis and hypertension and the increased content of advanced glycation endproducts and their receptors in the blood of patients. Samples of diabetic patients sera and the LMW-AGE standard were prepared similarly to the above ELISA competition test. To our knowledge, this is the first publication that describes different types and fractions of advanced glycation products and as many as 3 types of receptors for AGEs. Cardiovasc. PubMed 2016 Aug;33(4):607-17. doi: 10.1007/s10719-016-9679-x. The variety of ligands allows SR-A receptors to participate in numerous macrophage functions. Advanced glycation end-products (AGEs) constitute a non-homogenous, chemically diverse group of compounds formed either exogeneously or endogeneously on the course of various pathways in the human body.

Inhibition of this organ function is associated with higher concentration of circulating AGEs through increased formation as well as decreased clearance. (E) Dependence of AGEs concentration on the intake of clopidogrel; (n=48; YES ( 2.3510.783mg/ml), NO (0.95790.233mg/ml)). Patients with type 2 diabetes had significantly higher AGEs fluorescence and a much higher concentration of glycation end products and their receptors: SR-BI and sRAGE, compared to the group of patients with type 1 diabetes. Numerous studies indicate that a large amount of glycation end products affects the functional properties of the extracellular matrix, intracellular signal transduction and protein function, consequently leading to dysfunction of many organs8, 31. 2B). Particularly valuable is the determination of the MAGE content and the description of observations related to this new class of glycation products in the diabetic population. Clin. This confirms that with the increase of AGEs concentration, the level of uric acid increases in the blood, which is also confirmed by the research conducted by Koyama et al.40. Compr. Perrone, A., Giovino, A., Benny, J. Although a reduction in dietary AGEs has been shown to offer health benefits, currently there are no guidelines regarding safe and optimal intake (7). Research shows that tobacco smoke is one of the sources of environmental exposure to glycation end products46. For example, the experiment performed by Raposeiras-Roubin et al.44 have shown that increased serum sRAGE levels are associated with increased heart failure, especially in patients with ischemic heart disease. [18] They form photosensitizers in the crystalline lens,[19] which has implications for cataract development. An association was also demonstrated between the occurrence of retinopathy in patients and. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Their determination may allow the disease progression and the effectiveness of the therapy to be monitored. A number of drugs considered to be AGE inhibitors have been developed. anti-inflammatory drugs with anti-glycation properties (diclofenac, acetylsalicylic acid), metabolically active drugs and vitamins with anti-AGE properties (pyridoxamine, metformin), antioxidants and free radical scavengers (herbal extracts rich in flavonoids, carnosine) and AGE inhibitors with chelating properties (pyridoxamine, acarbose).

An a-glucosidase inhibitor, acarbose treatment decreases serum levels of glyceraldehyde-derived advanced glycation end products (AGEs) in patients with type 2 diabetes. Therefore, a diet full of colorful fruits, vegetables, herbs, and spices may help protect against the damaging effects of AGEs. AGEs contribute also to the development of cardiovascular diseases, as evidenced by the relationship between the results obtained during the experiments and the blood parameters of patients (HDL cholesterol, uric acid) treated in the Diabetes Clinic. It is the first identified transmembrane receptor belonging to the immunoglobulin superfamily, capable of binding a broad repertoire of ligands. Cell Biochem. The Effects of Dietary Advanced Glycation End-Products on - MDPI In addition, cooking meat with acidic ingredients, such as vinegar, tomato juice, or lemon juice, can reduce AGE production by up to 50% (7). [34], Nevertheless, the resistance of extracellular matrix proteins to proteolysis renders their advanced glycation end products less conducive to being eliminated. Med. While low levels are generally nothing to worry about, high levels have been shown to cause oxidative stress and inflammation (5). Among these emerge the quantification of advanced glycation end products (AGEs) given their increased levels due to chronic hyperglycemia, while also being related to the induction of different stress-associated cellular responses and proinflammatory mechanisms involved in the progression of chronic complications of DM. Retinopathy and fluorescence value of total soluble AGEs (p = 0.003; Fig. Advanced glycation end products are very heterogeneous, making difficult their assessment in blood, tissues, and cells.
