Advanced Glycation End-Product Cross-links

Molecular classification
Protein-protein adduct, Protein-lipid adduct, Protein-nucleic acid adduct
01

Overview

Advanced glycation end-product (AGE) cross-links are stable, covalent bonds formed between proteins, lipids or nucleic acids as a result of nonenzymatic reactions with reducing sugars. This process, known as glycation, leads to the formation of AGEs that accumulate in tissues over time, especially in long-lived proteins such as collagen. AGE cross-linking is a hallmark of aging and is accelerated under hyperglycemic conditions such as diabetes. They increase stiffness and brittleness of tissues, reduce flexibility and elasticity, and trigger inflammatory signaling pathways. Therapeutic strategies target AGE formation, break existing cross-links, or block AGE receptor interaction.
