Insulin protects apoptotic cardiomyocytes from hypoxia/reoxygenation injury through the sphingosine kinase/sphingosine 1-phosphate axis.

PLoS ONE, 2013
ObjectiveExperimental and clinical studies have shown that administration of insulin during reperfusion is cardioprotective, but the mechanisms underlying this effect are still unknown.

Advances in the treatment of systemic lupus erythematosus: Biologicals, small‐molecular agents, and cell‐depleting therapies coming to the clinic

Journal of Internal Medicine, EarlyView.
Abstract Systemic lupus erythematosus (SLE; lupus) remains a particular challenge for the practicing clinician on account of its chronic undulating and unpredictable course, its diverse manifestations, and—until recently—limited treatment options all associated with considerable downsides.

Sphingosine-1-phosphate receptor 3 mediates sphingosine-1-phosphate induced release of weibel-palade bodies from endothelial cells.

PLoS ONE, 2014
Sphingosine-1-phosphate (S1P) is an agonist for five distinct G-protein coupled receptors, that is released by platelets, mast cells, erythrocytes and endothelial cells.

Osteoporosis and Periodontitis: Two‐Way Epidemiological and Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review investigates the main mechanistic pathways connecting local periodontitis to systemic osteoporosis. Seven interconnected mechanisms are identified. ABSTRACT Osteoporosis and periodontitis are highly prevalent, chronic inflammatory diseases that constitute a major global health burden.

A facile enzymatic synthesis of sphingosine-1-phosphate and dihydrosphingosine-1-phosphate.

Journal of Lipid Research, 1989
A procedure is described to prepare sphingosine-1-phosphate by treatment of sphingosylphosphocholine with phospholipase D, isolated from Streptomyces chromofuscus.

Understanding exosomes in diabetic wound healing

Periodontology 2000, EarlyView.
Abstract Background Diabetic wounds signify a major complication of diabetes mellitus, characterized by chronic inflammation, compromised angiogenesis, and high risk of infection, amputation, and mortality. Contemporary therapies remain limited in efficacy and durability.

Mechanisms of sphingosine and sphingosine 1-phosphate generation in human platelets

Journal of Lipid Research, 2005
The bioactive molecule sphingosine 1-phosphate (S1P) is abundantly stored in platelets and can be released extracellularly. However, although they have high sphingosine (Sph) kinase activity, platelets lack the de novo sphingolipid biosynthesis necessary

Histiocytes: Multifaceted Regulators of Health and Disease

Veterinary Clinical Pathology, EarlyView.
ABSTRACT The mononuclear phagocyte system encompasses macrophages, dendritic cells (DCs), and monocytes. Tissue‐resident macrophages and dendritic cells arise during embryogenesis and are replenished either through self‐renewal or by monocytes during inflammation.

Enzymatic Measurement of Sphingosine 1-Phosphate

Analytical Biochemistry, 1999
Sphingosine 1-phosphate (SPP) is a sphingolipid metabolite which has novel dual actions acting as both an intracellular second messenger and a ligand for a family of G protein-coupled receptors. This paper describes a rapid enzymatic method to quantify mass levels of SPP in serum, mammalian tissues, and cultured cells.

Antagonizing the S1P-S1P3 Axis as a Promising Anti-Angiogenic Strategy

Metabolites
Background: Angiogenesis, the process of new blood vessel formation, is critically regulated by a balance of pro- and anti-angiogenic factors. This process plays a central role in tumor progression and is modulated by tumor cells. Sphingosine-1-phosphate
