鞘氨醇-1-磷酸(S1P)是一种脂质,具有代谢中间体和细胞信号分子的功能。当形成具有不同细胞外S1P浓度的室室,用于调节免疫和血管系统以及病理条件下的功能时,这些作用就被整合在一起。S1P浓度的梯度是通过组织内专门表达S1P代谢途径的细胞组织来实现的。S1P浓度梯度支持S1P信号调节体内生理的能力。本文将讨论S1P梯度形成和维持的必要机制,目的是了解简单的脂质如何控制复杂的生理。
Sphingosine-1-phosphate (S1P) is a lipid that functions as a metabolic intermediate and a cellular signaling molecule. These roles are integrated when compartments with differing extracellular S1P concentrations are formed that serve to regulate functions within the immune and vascular systems, as well as during pathologic conditions. Gradients of S1P concentration are achieved by the organization of cells with specialized expression of S1P metabolic pathways within tissues. S1P concentration gradients underpin the ability of S1P signaling to regulate in vivo physiology. This review will discuss the mechanisms that are necessary for the formation and maintenance of S1P gradients, with the aim of understanding how a simple lipid controls complex physiology.
