530. GPR133调控成骨分化：骨质疏松新疗法
from 知为谁 · host 知为谁
该科学研究论文来自《信号转导与靶向治疗》期刊，其核心内容是确定 GPR133/ADGRD1 是一种新型的骨骼形成调节剂。文章详细探讨了该粘附 G 蛋白偶联受体（aGPCR）对成骨细胞分化和功能的关键影响，指出其缺失会导致小鼠出现骨质疏松的表型。研究人员通过体外和体内实验证明，GPR133/ADGRD1 的激活机制涉及与其内源性配体 PTK7 的相互作用以及机械力的刺激。此外，该研究发现小分子激动剂 AP503 能够有效激活 GPR133/ADGRD1，减轻卵巢切除术小鼠模型中的骨质疏松症状，表明该受体是治疗骨质疏松症的一个有前景的治疗靶点。内容来源：https://www.nature.com/articles/s41392-025-02291-y
