[摘 要] 鞘氨醇⁃1⁃磷酸(sphingosine⁃1⁃phosphate,S1P)信号通路在维持血管稳态、调节炎症反应及促进心肌细胞存活方面
具有关键作用,然而现有关于S1P研究主要聚焦于大血管和整体心脏功能,对其在心脏微循环障碍这一驱动心肌缺血、心力衰
竭及心肌纤维化的核心病理过程中的作用尚缺乏系统性阐释。本综述基于微循环视角,探讨S1P受体不同亚型在微血管内
皮、平滑肌及免疫细胞中的表达分布与功能差异。进一步总结S1P通路调节剂(如Fingolimod、Siponimod)及鞘氨醇激酶抑制剂
在心肌缺血、心力衰竭、糖尿病性心肌病和高血压性心脏病等疾病模型中的研究进展与应用局限。在此基础上,提出结合生物
标志物分层、亚型选择性调控、靶向纳米载体及多靶点联合用药的精准干预策略。未来,有望通过单细胞空间组学解析S1P受
体动态表达,优化靶向载体设计及实施分层化临床试验,加速S1P通路调控策略在微循环障碍相关性心脏疾病中的临床转化。

[Abstract] The sphingosine⁃1⁃phosphate(S1P)signaling axis plays a pivotal role in maintaining vascular homeostasis,modulating
inflammatory responses,and promoting cardiomyocyte survival. However,current research has largely centered on the macrovascular
and global cardiac function,with limited systematic exploration of S1P’s role in the cardiac microcirculation,a key driver of
myocardial ischemia,heart failure,and fibrosis. In this review,we adopt a microcirculatory perspective to delineate the differential
expression patterns and functional roles of S1P receptor subtypes in microvascular endothelial cells,vascular smooth muscle cells,and
immune cell populations. We further summarize the therapeutic advances and limitations of S1P modulators,including fingolimod,
siponimod,and sphingosine kinase inhibitors,in models of myocardial ischemia,heart failure,diabetic cardiomyopathy,and
hypertensive heart disease. Precision intervention strategies are then proposed,integrating biomarker ⁃ guided patient stratification,
receptor⁃subtype selective modulation,targeted nanocarrier delivery,and multi⁃target combination therapy. Looking ahead,single⁃cell
spatial omics to resolve dynamic S1P receptor expression,optimized carrier design,and stratified clinical trials hold promises to
accelerate the translational application of S1P pathway⁃based therapies in microcirculation⁃related cardiac diseases.
