摘要: 磷酸鞘氨醇(S1P)是一种活性高的膜磷脂类代谢物,对心血管系统具有重要的生理作用。鞘氨醇激酶(SphK)是一种脂肪酶,对维持体内S1P水平的稳定非常重要。S1P通过催化调节与细胞表面的G蛋白偶联受体(S1PR1-5)的结合,从而在心血管疾病中发挥不同的生理学效应,如参与调控动脉粥样硬化、心肌缺血再灌注损伤、心肌梗死、心力衰竭等疾病的发生发展,维持血管内皮细胞屏障功能,保护内皮糖萼层,白细胞黏附以及炎性反应等生理病理过程。

Abstract: Sphingosine-1-phosphate (S1P) is a highly active membrane phospholipid metabolite with important physiological roles in the cardiovascular system. Sphingosine kinase (SphK) is a lipase that is important for maintaining stable S1P levels in vivo. S1P exerts different physiological effects in cardiovascular diseases by catalytically regulating the binding of S1P to G protein-coupled receptors (S1PR1-5) on the cell surface, thus exerting different physiological effects in cardiovascular diseases.For example, they are involved in regulating the development of diseases such as atherosclerosis, myocardial ischemia-reperfusion injury, myocardial infarction, heart failure and other diseases, maintaining the barrier function of vascular endothelial cells, protecting the endothelial glycocalyx layer, leukocyte adhesion, inflammatory reactions and other pathophysiologic processes.

Key words: sphingosine-1-phosphate, sphingosine kinase, cardiovascular diseases, endothelial glycocalyx layer
