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]

PLoS ONE, 2014
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.

Sphingosine-1-phosphate receptors and innate immunity [PDF]

Cellular Microbiology, 2018
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.

Synergy between sphingosine 1-phosphate and lipopolysaccharide signaling promotes an inflammatory, angiogenic and osteogenic response in human aortic valve interstitial cells.

PLoS ONE, 2014
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-

Targeting Sphingosine-1-Phosphate Receptors in Cancer [PDF]

Anti-Cancer Agents in Medicinal Chemistry, 2011
Sphingosine 1-phosphate (S1P) is a bioactive lipid with diverse biological functions, including cell proliferation, differentiation, angiogenesis, chemotaxis, and migration. Many of the activities of S1P are mediated through five closely related G-protein-coupled receptors of the sphingosine-1-phosphate receptor family (S1PR) which play a crucial role ...

Sphingosine Kinase 1 Signaling in Breast Cancer: A Potential Target to Tackle Breast Cancer Stem Cells

Frontiers in Molecular Biosciences, 2021
Sphingosine kinases (SPHKs) are conserved lipid enzymes that catalyze the formation of sphingosine-1-phosphate (S1P) through ATP-dependent phosphorylation of sphingosine.

Sphingosine 1-Phosphate Analogs as Receptor Antagonists [PDF]

Journal of Biological Chemistry, 2005
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.

Structural determinants of sphingosine‐1‐phosphate receptor selectivity

Archiv der Pharmazie, 2023
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 ...

In silico Docking Studies of Fingolimod and S1P1 Agonists

Frontiers in Pharmacology, 2020
The sphingosine-1-phosphate receptor 1 (S1P1), originally the endothelial differentiation gene 1 receptor (EDG-1), is one of five G protein–coupled receptors (GPCRs) S1P1–5 that bind to and are activated by sphingosine-1-phosphate (S1P). The lipid S1P is

Sphingosine-1–Phosphate, FTY720, and Sphingosine-1–Phosphate Receptors in the Pathobiology of Acute Lung Injury [PDF]

American Journal of Respiratory Cell and Molecular Biology, 2013
Abstract Acute lung injury (ALI) attributable to sepsis or mechanical ventilation and subacute lung injury because of ionizing radiation (RILI) share profound increases in vascular permeability as a key element and a common pathway driving increased morbidity and mortality.
