Background The bone marrow niche supports hematopoietic cell development through intimate contact with multipotent stromal mesenchymal stem cells; however, the intracellular signaling, function, and regulation of such supportive niche cells are still ...

Migration of germline progenitor cells is directed by sphingosine-1-phosphate signalling in a basal chordate. [PDF]
The colonial ascidian Botryllus schlosseri continuously regenerates entire bodies in an asexual budding process. The germ line of the newly developing bodies is derived from migrating germ cell precursors, but the signals governing this homing process ...

Sphingosine 1-Phosphate Analogs as Receptor Antagonists [PDF]
Sphingosine 1-phosphate (S1P) is a lysophospholipid mediator that evokes a variety of cell and tissue responses via a set of cell surface receptors. The recent development of S1P receptor agonists, led by the immunomodulatory pro-drug FTY720, has revealed that S1P signaling is an important regulator of lymphocyte trafficking.

Sphingosine-1-phosphate receptors and innate immunity [PDF]
Sphingosine-1-phosphate (S1P) is a signalling lipid that regulates many cellular processes in mammals. One well-studied role of S1P signalling is to modulate T-cell trafficking, which has a major impact on adaptive immunity. Compounds that target S1P signalling pathways are of interest for immune system modulation.

Sphingosine-1-phosphate signaling and the gut-liver axis in liver diseases
The liver is the central organ involved in lipid metabolism and the gastrointestinal (GI) tract is responsible for nutrient absorption and partitioning. Obesity, dyslipidemia and metabolic disorders are of increasing public health concern worldwide, and ...

High density lipoprotein stimulated migration of macrophages depends on the scavenger receptor class B, type I, PDZK1 and Akt1 and is blocked by sphingosine 1 phosphate receptor antagonists. [PDF]
HDL carries biologically active lipids such as sphingosine-1-phosphate (S1P) and stimulates a variety of cell signaling pathways in diverse cell types, which may contribute to its ability to protect against atherosclerosis.

Structural determinants of sphingosine‐1‐phosphate receptor selectivity
AbstractFingolimod, the prodrug of fingolimod‐1‐phosphate (F1P), was the first sphingosine‐1‐phosphate receptor (S1PR) modulator approved for multiple sclerosis. F1P unselectively targets all five S1PR subtypes. While agonism (functional antagonism via receptor internalization) at S1PR1 leads to the desired immune modulatory effects, agonism at S1PR3 ...

Given that the bioactive lipid sphingosine 1-phosphate is involved in cardiovascular pathophysiology, and since lipid accumulation and inflammation are hallmarks of calcific aortic stenosis, the role of sphingosine 1-phosphate on the pro-inflammatory/pro-

Sphingosine 1-phosphate receptors: do they have a therapeutic potential in cardiac fibrosis? [PDF]
Sphingosine 1-phosphate (S1P) is a bioactive lipid that is characterized by a peculiar mechanism of action. In fact, S1P, which is produced inside the cell, can act as an intracellular mediator, whereas after its export outside the cell, it can act as ...

Requirement for sphingosine kinase 1 in mediating phase 1 of the hypotensive response to anandamide in the anaesthetised mouse [PDF]
In the isolated rat carotid artery, the endocannabinoid anandamide induces endothelium-dependent relaxation via activation of the enzyme sphingosine kinase (SK).
