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

Parisa Younessi, Ali Yoonessi

Abstract



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 progression of AD. It is also suggested that interaction between an advanced glycation end product (AGE) and its receptor (RAGE) results in glial activation as well as cy-tokine release and reactive oxygen species release. The use of antioxidants, receptor mediated compounds and reactive oxygen species scavenging enzyme produce an opportunity to in-tervene with AGE-RAGE signaling pathway, and thereby to slow down the progression of aging-related diseases.
