晚期糖基化终末产物对骨组织生物力学影响的研究进展

Advanced glycation end-products (AGEs) are the products of non-enzymatic reactions between free amino groups of macromolecules and reducing sugars. AGEs accumulation in bone tissues changes the activity and function of bone cells by binding to their surface receptors, causing abnormalities in the process of bone remodeling. AGEs accumulation can also change the original structure and mineral deposition of bone collagen, affect the micro-mechanical properties of bone tissues, and further reduce bone strength and toughness, increase the bone fracture risk, which will lead to bone diseases and do great harm to human health. This article summarized the causes of AGEs and their detection methods, and reviewed previous studies about the effects of AGEs accumulation on bone biomechanics at micro and macro levels, so as to provide references for the early diagnosis and treatment of bone diseases in clinic.
