摘要
在心肌组织、血管平滑肌细胞、内皮细胞和血管壁周围的神经纤维末梢以及血液中某些细胞存在内源性大麻素和相应的大麻素(CB)受体。在不同的动物模型和器官,内源性大麻素发挥调节血压和扩张血管等效应。内源性大麻素还在减少休克和心肌梗死所致循环和心脏损伤方面发挥重要作用,在心肌预适应中亦发挥关键作用。目前对内源性大麻素在心血管系统中作用的研究还处于起步阶段,本文对内源性大麻素系统在心血管系统中的来源和分布,对血管和心脏的作用及其机制方面的研究进展作简要介绍。
Endocannabinoids and its corresponding receptors exist in myocardium, vascular smooth muscle cells, endothelial cells, nerve cells within blood vessel walls and some of circulating cells in blood. Endocannabinoids have different roles such as modulating blood pressure and vasculardilation in cardiovascular system in different models and organs of animal or human. It might mediate cardiacprotection and modulating circulation in shock and myocardial infarction. Also, endocannabinoids might play a key role in cardiac preconditioning. The study of endocannabinoids in cardiovascular system was just start. We introduced the progress in the source and distribution of endocannabinoids in cardiovascular system, and the action and mechanisms of endocannabinoids in blood vessels and hearts in the present review.
