R-spondin2(Rspo2)是蛋白质家族RSPOs成员之一,其可以通过富含亮氨酸重复序列的G蛋白偶联受体4/5(leucine-rich repeat-containing G protein-coupled receptor 4/5,LGR4/5)、细胞表面跨膜E3泛素连接酶ZNRF3/RNF43(zinc and ring finger...R-spondin2(Rspo2)是蛋白质家族RSPOs成员之一,其可以通过富含亮氨酸重复序列的G蛋白偶联受体4/5(leucine-rich repeat-containing G protein-coupled receptor 4/5,LGR4/5)、细胞表面跨膜E3泛素连接酶ZNRF3/RNF43(zinc and ring finger 3/ring finger protein 43)、硫酸乙酰肝素蛋白聚糖(heparan sulfate proteoglycans,HSPGs)和含GTP酶激活蛋白质1的IQ基序(IQ motif-containing GTPase-activating protein 1,IQGAP1)来调控Wnt/β连环蛋白(catenin)信号通路,Wnt/β-catenin信号通路是目前研究最广泛且与基础骨生物学直接相关的信号通路,该通路中任何一环节出现问题都可能对骨的调控产生影响。近年来研究发现,Rspo2可以通过Wnt/β-catenin对成骨细胞(osteoblast,OB)、破骨细胞(osteoclast,OC)和软骨细胞产生作用,并参与一些骨骼疾病如脊柱后纵韧带骨化(ossification of the posterior longitudinal ligament,OPLL)、骨关节炎(osteoarthritis,OA)和类风湿性关节炎(rheumatoid arthritis,RA)的发生发展,因此对Rspo2的研究可能会成为骨相关疾病新的治疗方向。本文结合最新研究进展,就Rspo2的结构和主要功能、Rspo2调控Wnt/β-catenin信号通路的相关机制及其对骨骼系统的影响作一综述,以期为骨相关疾病的防治提供新的思路和途径。展开更多
