Osteoporosis (OP), characterized by an imbalance of bone remodeling between formation and resorption, has become a health issue worldwide. The receptor for advanced glycation end product (RAGE), a transmembrane protein in the immunoglobin family, has multiple ligands and has been involved in many chronic diseases, such as diabetes and OP. Increasing evidence shows that activation of the RAGE signaling negatively affects bone remodeling. Ligands, such as advanced glycation end products (AGEs), S100, β-amyloid (Aβ), and high mobility group box 1 (HMGB1), have been well documented that they may negatively regulate the proliferation and differentiation of osteoblasts and positively stimulate osteoclastogenesis by activating the expression of RAGE. In this review, we comprehensively discuss the structure of RAGE and its biological functions in the pathogenesis of OP. The research findings suggest that RAGE signaling has become a potential target for the therapeutic management of OP.
骨质疏松症(OP)的特征是骨形成和吸收之间的骨重建失衡,已成为全球范围内的健康问题。晚期糖基化终产物(RAGE)受体是免疫球蛋白家族中的一种跨膜蛋白,具有多种配体,参与许多慢性疾病,如糖尿病和 OP。越来越多的证据表明,RAGE 信号的激活会对骨重建产生负面影响。配体,如晚期糖基化终产物(AGEs)、S100、β-淀粉样蛋白(Aβ)和高迁移率族蛋白 1(HMGB1),已被充分证明它们可能通过激活 RAGE 的表达来负调控成骨细胞的增殖和分化,并正刺激破骨细胞生成。在这篇综述中,我们全面讨论了 RAGE 的结构及其在 OP 发病机制中的生物学功能。研究结果表明,RAGE 信号已成为治疗 OP 的潜在靶点。
