摘要:

文题释义:
大麻素受体:是内源性大麻素系统的重要组成成分,包括CB1、CB2、G蛋白偶联受体55和瞬时受体电位阳离子通道1等受体,表达于交感神经末梢和成骨细胞、破骨细胞等细胞表面,可作为靶点与大麻素配体结合,参与成骨细胞、破骨细胞活性和形成的调控过程。
骨改建:通过成骨细胞形成骨和破骨细胞吸收骨及骨细胞的作用,骨组织结构发生变化的过程,病理状态下可表现为骨量和骨转换率的增加或减低,是牙周炎、骨质疏松症的生物学基础。
背景:大麻素受体如何调节成骨细胞和破骨细胞,维持正常的骨改建过程,在骨骼正常发育、骨量维持以及骨质疏松和牙周炎的治疗等方面具有重要意义。
目的:综述大麻素受体与骨改建的关系及相关影响因素,为骨质疏松、牙周炎治疗以及其在临床其他领域的应用提供思路。
方法:检索 PubMed、FMRS、万方数据库、CNKI中国期刊全文数据库2001年7月至2020年7月收录的相关文献。英文检索词为“endocannabinoid systems,the endocannabinoid receptors,osteoblasts,osteoclasts,bone mass,bone remodeling,oral health,osteoporosis,periodontitis”,中文检索词为“内源性大麻素系统,大麻素受体,成骨细胞,破骨细胞,骨量,骨改建,口腔健康,骨质疏松症,牙周炎”,最终纳入77篇文献进行归纳总结。
结果与结论:①骨改建依赖于成骨细胞和破骨细胞的相互作用,骨吸收与骨形成之间的失衡会影响骨改建过程,导致骨质疏松、牙周炎等骨骼炎症性疾病;②内源性大麻素系统包含多种受体,均属于G蛋白偶联超家族成员;两种主要的受体(大麻素Ⅰ型和大麻素Ⅱ型)在成骨细胞、破骨细胞以及骨髓间充质干细胞等骨相关细胞中均存在表达;③在天然配体或人工合成激动剂的作用下,大麻素受体可通过不同的代谢通路在体内外产生特定的生理效应,从而调节骨细胞的生成和分化,最终影响骨量和骨代谢;④进一步研究其对骨形成和骨丢失的机制,为骨相关疾病的临床工作提供新的治疗思路成为目前研究的重点。

Abstract: BACKGROUND: How cannabinoid receptors regulate the role of osteoblasts and osteoclasts and maintain the normal process of bone remodeling is of great significance for the normal development of bone, the maintenance of bone mass and the treatment of osteoporosis and periodontitis. 
OBJECTIVE: To review the relationship between cannabinoid receptor and bone remodeling and its related factors, so as to provide ideas for the treatment of osteoporosis, periodontitis and other clinical applications.
METHODS: We searched relevant articles published from July 2001 to July 2020 in PubMed, FMRS, CNKI, WanFang databases with the keywords of “endocannabinoid systems, the endocannabinoid receptors, osteoblasts, osteoclasts, bone mass, bone remodeling, oral health, osteoporosis, periodontitis” in Chinese and English, respectively. Finally, 77 articles met the criteria for review.
RESULTS AND CONCLUSION: Bone remodeling depends on the interaction between osteoblasts and osteoclasts. The imbalance between bone resorption and bone formation will affect the process of bone remodeling and lead to bone inflammatory diseases such as osteoporosis and periodontitis. The endogenous cannabinoid system contains a variety of receptors, all of which belong to the G protein coupling superfamily. The two main receptors (cannabinoid type I and cannabinoid type II) are expressed in osteoblasts, osteoclasts and bone marrow mesenchymal stem cells and other bone-related cells. Under the action of natural ligands or synthetic agonists, cannabinoid receptors can produce specific physiological effects in vivo and in vitro through different metabolic pathways, thus regulating the generation and differentiation of osteocytes, and eventally affecting bone mass and bone metabolism. Further research on the mechanism of bone formation and bone loss has been a focus of current research, to provide new treatment ideas for the clinical work of bone-related diseases.

Key words: cannabinoid receptor, osteoblast, osteoclast, bone marrow mesenchymal stem cells, bone mass, bone remodeling, osteoporosis, periodontitis
