Sphingosine 1-phosphate (S1P) receptor subtypes S1P1 and S1P3, respectively, regulate lymphocyte recirculation and heart rate.

Sphingosine 1-phosphate (S1P) influences heart rate, coronary artery caliber, endothelial integrity, and lymphocyte recirculation through five related high affinity G-protein-coupled receptors. Inhibition of lymphocyte recirculation by non-selective S1P receptor agonists produces clinical immunosuppression preventing transplant rejection but is associated with transient bradycardia. Understandi...

Sphingosine 1-Phosphate (S1P) Regulates Vascular Contraction via S1P3 Receptor: Investigation Based on a New S1P3 Receptor Antagonist □S

Sphingosine 1-phosphate (S1P) induces diverse biological responses in various tissues by activating specific G proteincoupled receptors (S1P1–S1P5 receptors). The biological signaling regulated by S1P3 receptor has not been fully elucidated because of the lack of an S1P3 receptor-specific antagonist or agonist. We developed a novel S1P3 receptor antagonist, 1-(4chlorophenylhydrazono)-1-(4-chlor...

Sphingosine 1-phosphate (S1P) regulates vascular contraction via S1P3 receptor: investigation based on a new S1P3 receptor antagonist.

Sphingosine 1-phosphate (S1P) induces diverse biological responses in various tissues by activating specific G protein-coupled receptors (S1P(1)-S1P(5) receptors). The biological signaling regulated by S1P(3) receptor has not been fully elucidated because of the lack of an S1P(3) receptor-specific antagonist or agonist. We developed a novel S1P(3) receptor antagonist, 1-(4-chlorophenylhydrazono...

Sphingosine kinase 1/sphingosine-1-phosphate (S1P)/S1P receptor axis is involved in ovarian cancer angiogenesis

Sphingosine kinase (SphK)/sphingosine-1-phosphate (S1P)/S1P receptor (S1PR) signaling pathway has been implicated in a variety of pathological processes of ovarian cancer. However, the function of this axis in ovarian cancer angiogenesis remains incompletely defined. Here we provided the first evidence that SphK1/S1P/S1PR1/3 pathway played key roles in ovarian cancer angiogenesis. The expressio...

The Sphingosine-1-Phosphate (S1P) Lysophospholipid Receptor S1P3 Regulates MAdCAM-1+ Endothelial Cells in Splenic Marginal Sinus Organization

Marginal zones (MZs) are microdomains in the spleen that contain various types of immune cells, including MZ B cells, MOMA1(+) metallophilic macrophages, and mucosal addressin cell adhesion molecule 1 (MAdCAM-1)(+) endothelial cells. MAdCAM-1(+) and MOMA1(+) cells line the sinus, that separates MZs from splenic follicles. Here we show that a receptor for the lysophospholipid sphingosine-1-phosp...
