An update on the biology of sphingosine 1-phosphate receptors [PDF]

Journal of Lipid Research, 2014
Sphingosine 1-phosphate (S1P) is a membrane-derived lysophospholipid that acts primarily as an ex-tracellular signaling molecule. Signals initiated by S1P are transduced by five G protein-coupled receptors, named S1P1-5 Cellular and temporal expression of the S1P receptors (S1PRs) determine their specific roles in various organ systems, but they are ...

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 ...

G protein-coupled receptor kinase 3 modulates mesenchymal stem cell proliferation and differentiation through sphingosine-1-phosphate receptor regulation

Stem Cell Research & Therapy, 2022
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 ...

Sphingosine-1-phosphate signaling and the gut-liver axis in liver diseases

Liver Research, 2019
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]

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.

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-

Modulators of the Sphingosine 1-phosphate receptor 1 [PDF]

Bioorganic & Medicinal Chemistry Letters, 2013
The Sphingosine 1-phosphate receptor (S1P-R) signaling system has proven to be of biological and medical importance in autoimmune settings. S1P1-R is a validated drug target for multiple sclerosis (MS) for which FTY720 (Fingolimod), a S1P1,3-5-R pan-agonist, was recently approved as the first orally active drug for the treatment of relapsing-remitting ...

Sphingosine 1-phosphate modulates antigen capture by murine langerhans cells via the S1P2 receptor subtype [PDF]

, 2012
Dendritic cells (DCs) play a pivotal role in the development of cutaneous contact hypersensitivity (CHS) and atopic dermatitis as they capture and process antigen and present it to T lymphocytes in the lymphoid organs.

Sphingosine 1-phosphate in renal diseases [PDF]

, 2013
Because of its highly bioactive properties sphingosine 1-phosphate (S1P) is an attractive target for the treatment of several diseases. Since the expression of sphingosine kinases as well as S1P receptors was demonstrated in the kidney, questions about ...

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.
