Epidemiological studies demonstrate the role of early and intensive glycemic control in the prevention of micro and macrovascular disease in both type 1 and type 2 diabetes mellitus (DM). Hyperglycemia elicits several pathways related to the etiopathogenesis of cardiovascular disease (CVD), including the generation of advanced glycation end products (AGEs). In this review, we revisit the role played by AGEs in CVD based in clinical trials and experimental evidence. Mechanistic aspects concerning the recognition of AGEs by the advanced glycosylation end product-specific receptor (AGER) and its counterpart, the dolichyl-diphosphooligosaccharide-protein glycosyltransferase (DDOST) and soluble AGER are discussed. A special focus is offered to the AGE-elicited pathways that promote cholesterol accumulation in the arterial wall by enhanced oxidative stress, inflammation, endoplasmic reticulum stress and impairment in the reverse cholesterol transport (RCT).
流行病学研究表明,在 1 型和 2 型糖尿病(DM)中,早期和强化血糖控制可预防微血管和大血管疾病。高血糖引发了与心血管疾病(CVD)发病机制相关的几种途径,包括晚期糖基化终产物(AGEs)的产生。在这篇综述中,我们根据临床试验和实验证据重新审视了 AGEs 在 CVD 中的作用。讨论了晚期糖基化终产物特异性受体(AGER)及其对应物、二氢吡啶二磷酸寡糖蛋白糖基转移酶(DDOST)和可溶性 AGER 识别 AGE 的机制方面。特别关注通过增强氧化应激、炎症、内质网应激和损害胆固醇逆转运(RCT)来促进胆固醇在动脉壁中积累的 AGE 诱导途径。
