| 钙敏感受体感受细胞外的钙离子水平，调控一系列激素的释放以维持机体的钙稳态。钙稳态的调节过程与骨代谢相偶联，
钙敏感受体通过直接或间接对破骨和成骨细胞的调控，动员或者抑制骨钙入血。虽然钙敏感受体已被证实调控骨代谢，但是详尽

受体及相关作用因子治疗骨代谢疾病的研究提供参考。 |
| 英文摘要: |
| Calcium sensing receptor senses the extracellular calcium and regulates the secretion of hormones to maintain the
calcium homeostasis. Calcium homeostasis is coupled to bone metabolism, in which calcium sensing receptor, directly or indirectly,
regulates osteoblasts and osteoclasts to control bone resorption and formation, thus the calcium transferring from bone to blood is either
enhanced or inhibited. Though, calcium sensing receptor is demonstrated to be indispensable in bone metabolism, detailed mechanisms
remain to be discovered. It is agreed that high extracellular calcium activates calcium sensing receptor which sequentially suppresses the
secretion of PTH and promotes the secretion of CT. Thus, bone formation is enhanced by suppression of osteoclasts and activation of
osteoblasts. In this article, the research progress of calcium sensing receptor in the regulation of bone metabolism is reviewed, with the
purpose of promoting the research in calciumsensing receptor and related factors to cure bone metabolismdiseases. |
