1-磷酸鞘氨醇及其信号传导在中枢神经系统疾病中的研究进展

1-磷酸鞘氨醇(sphingosine 1-phosphate,S1P)作为一种鞘脂代谢物已成为调节各种生理过程的关键物质,参与分化、增殖、迁移、形态发生、细胞骨架形成、黏附、凋亡等过程。1-磷酸鞘氨醇既可以与细胞膜上相应的受体结合激活S1P-S1PR信号通路,也可以在细胞内发挥作用。近年来研究发现其水平变化与中枢神经系统疾病的发生发展存在一定的联系。本文综述了1-磷酸鞘氨醇在神经系统疾病发生及治疗中的最新认识,并进一步阐明其在中枢神经系统疾病治疗及发展中的分子机制。

Research progress of sphingosine 1-phosphate and its signal transduction in central nervous system diseases

Sphingosine 1-phosphate(S1P),as a sphingolipid metabolite,has become a key substance in regulating various physiological processes,involved in differentiation,proliferation,migration,morphogenesis,cytoskeleton formation,adhesion,apoptosis,etc.process.Sphingosine 1-phosphate can not only activate the S1P-S1PR signaling pathway by binding to the corresponding receptors on the cell membrane,but also play a role in the cell.In recent years,studies have found that there is a certain relationship between its level changes and the occurrence and development of central nervous system diseases.This article reviews the latest knowledge of sphingosine-1-phosphate in the occurrence and treatment of nervous system diseases,and further clarifies its molecular mechanism in the treatment and development of central nervous system diseases.
