S1pr2 KO Mouse | NIDDK
A Spingosine-1-phosphate Receptor-2 (S1pr2) knockout mouse.. Sphingosine-1-phosphate (S1P), a sphingolipid metabolite, activates cell signaling by interacting with a family of G-protein-coupled cell-surface S1P receptors that activate different and overlapping signaling pathways. Three S1P receptors (S1P1, S1P2 and S1P3) are abundant in embryonic endothelial cells. S1P1 knockouts are embryonic lethals because of hemorrhage. S1P2 null mice did not exhibit embryonic lethality or phenotypic abnormalities. However, double null embryos (S1P1 S1P2 and S1P2 S1P3), and triple null embryos (S1P1 S1P2 S1P3) displayed a more severe vascular phenotype than did S1P1 null embryos, suggesting cooperative functions of the three S1P receptors.. ...
Targeting the Sphingolipid Signaling Pathway in Stroke | Stroke
To the Editor:. We congratulate Hasegawa et al1 for their innovative and thoroughly conducted study on the neuroprotective effect of the immunomodulatory sphingosine 1-phosphate (S1P) analog FTY720 (fingolimod) in a rat stroke model. Making use of a selective agonist of S1P receptor-1 (S1P1) and an antagonist selective for the sphingosine 1-phosphate receptors S1P1 and S1P3, they identified S1P1 as the crucial receptor that mediates the reduction of lesion size and the improved outcome after treatment with FTY720.. Besides the new mechanistic insight concerning the protective signaling pathway in stroke, this study corroborates the finding that the sphingolipid mediator FTY720 has a strong neuroprotective effect in experimental stroke, which has already been shown in mice by Shichita et al2 and our group.3 Also, Wacker et al4 described that cerebral ischemia induces sphingosine kinase-2, the enzyme responsible for the phosphorylation and thus activation of FTY720, which is abundantly expressed ...

A G protein-biased S1P1 agonist, SAR247799, protects endothelial cells without affecting lymphocyte numbers | Science Signaling
Endothelial dysfunction is a hallmark of tissue injury and is believed to initiate the development of vascular diseases. Sphingosine-1 phosphate receptor-1 (S1P1) plays fundamental physiological roles in endothelial function and lymphocyte homing. Currently available clinical molecules that target this receptor are desensitizing and are essentially S1P1 functional antagonists that cause lymphopenia. They are clinically beneficial in autoimmune diseases such as multiple sclerosis. In patients, several side effects of S1P1 desensitization have been attributed to endothelial damage, suggesting that drugs with the opposite effect, namely, the ability to activate S1P1, could help to restore endothelial homeostasis. We found and characterized a biased agonist of S1P1, SAR247799, which preferentially activated downstream G protein signaling to a greater extent than β-arrestin and internalization signaling pathways. SAR247799 activated S1P1 on endothelium without causing receptor desensitization and ...

Interfering with interferons | Science Signaling
Type I interferons (IFNs), which are mostly produced by plasmacytoid dendritic cells (pDCs), are critical to the immune response to viruses, but they are also implicated in autoimmune diseases and in viral and bacterial pathogenesis. Noting that selective agonists of sphingosine 1-phosphate receptor 1 (S1PR1), a G protein-coupled receptor (GPCR), suppress immunopathology without interfering with host defense, Teijaro et al. investigated the underlying mechanism. Treatment of mouse lung pDCs with the selective S1PR1 agonist CYM-5442 inhibited the production of IFN-α in response to influenza virus in vitro, whereas treatment with the S1PR1 antagonist W146 had the opposite effect. CYM-5442 also inhibited IFN-α production by pDCs in response to CpG oligonucleotides that trafficked to early endosomes and stimulated Toll-like receptor 9 (TLR9). Using pertussis toxin to block S1PR1-mediated activation of Gi/o proteins did not prevent CYM-5442 from inhibiting IFN-α production by pDCs exposed to ...

Abstract 20797: Sphingosine-1-Phosphate Receptor Agonist Fingolimod After Prolonged Circulatory Arrest Improves Cardiac and...
Introduction: Fingolimod, a sphingosine-1-phosphate receptor agonist, is used for the treatment of multiple sclerosis and exerts anti-inflammatory and antiapoptotic properties.. Hypothesis: We hypothesized that sphingosine-1-phosphate receptor activation with fingolimod during circulatory arrest inhibits apoptosis and inflammation leading to increased myocardial and cerebral functions after reperfusion with extracorporeal life support (ECLS).. Methods and Results: Ventricular fibrillation (VF) was induced in male Wistar rats. After 10 min of untreated VF, veno-arterial ECLS was instituted for 60 minutes. At the beginning of ECLS animals randomly received fingolimod or saline (control). Restoration of spontaneus circulation and 24 hours survival were higher in rats that received fingolimod (p = 0.03). Fingolimod treatment activated the cardioprotective reperfusion injury salvage kinase and survivor activating factor enhancement pathways leading to decreased cardiomyocyte apoptosis and reduced ...

Agonists of the sphingosine-1-phosphate (S1P) receptors, like fingolimod (FTY720), are a novel class of immunomodulators. Administration of these compounds prevents the egress of lymphocytes from primary and secondary lymphoid organs causing peripheral blood lymphopenia. Although it is well established that lymphopenia is mediated by S1P receptor type 1 (S1P1), the exact mechanism is still controversial. The most favored hypothesis states that S1P1 agonists cause internalization and loss of the cell surface receptor on lymphocytes, preventing them to respond to S1P. Hence, S1P1 agonists would behave in vivo as functional antagonists of the receptor. For this hypothesis to be valid, a true S1P1 antagonist should also induce lymphopenia. However, it has been reported that S1P1 antagonists fail to show this effect, arguing against the concept. Our study demonstrates that a S1P1 antagonist, W146, induces a significant but transient blood lymphopenia in mice and a parallel increase in CD4+ and CD8+
Glycerol-3-Phosphate (G3P) Colorimetric Assay Kit, 100 assays
Glycerol-3-phosphate (G3P) is an important intermediate for all living organisms. Glycerol-3-Phosphate is produced either by glycerol via glycerol kinase or by dihydroxyacetone phosphate through glycerol-3-phosphate dehydrogenase. In response to cellular signals, glycerol-3-phosphate can be utilized in multiple pathways: it can be further converted into glyceraldehyde-3-phosphate and enter glycolysis or rapidly generate NAD+ in brain or muscle tissues through the G3P shuttle or enter the lipid biosynthetic pathway. Recent studies have found that glycerol-3-phosphate is a novel regulator and plays a fundamental defense role in plant pathogenesis ...
Cutting Edge: Normal Regional Lymph Node Enrichment of Antigen-Specific Regulatory T Cells with Autoimmune Disease-Suppressive...
The mechanism of LN-specific, Ag-specific Treg enrichment might depend on factors regulating T cell homing to LN, encounter with self-Ag, and their retention in the LN. Homing of naive T cells and Treg to normal LN are known to involve CD62L, CCR7, and the chemokines CCL19 and CCL21 (15). Autoimmune diseases occur in mice deficient in CD62L or CCR7 (16, 17), for which we can now add a potential explanation: the loss of DS-Treg enrichment in regional LN. Treg retention may result from up-regulation of CD69 on Ag-specific Treg that temporarily sequester sphingosine 1-phosphate receptor type 1, which is required for T cell egress from LN (18). Additional mechanisms may involve Treg response to antiapoptotic and/or cellular proliferation signals (19). Constrained by T cell homeostatic mechanisms (20), the number or activity of DS-Treg in the regional LN would be maintained at a threshold 15- to 50-fold greater than those in the nondraining LN.. Additional mechanisms participate in Ag-specific Treg ...
FDA issues stricter warning for epilepsy drug Gilenya | Lopez McHugh LLP
The U.S. Food and Drug Administration has reviewed Novartis AGs multiple sclerosis drug Gilenya, and concluded that patients whove suffered a heart attack or stroke within the past six months shouldnt take it.. The review came about after a 59-year-old patient died in November, less than 24 hours after taking the first dose of the drug.. Europes drug regulator, the European Medicines Agency, recently requested stronger safety warnings for Gilenya after the agency concluded its review of the drug.. According to Dow Jones Newswires, Gilenya is currently the only oral MS drug on the market, and its recently been dogged by safety concerns.. A European Medicines Agency review of Gilenya states: While no cases of sudden or unexplained death had been reported in clinical studies at the time of its authorization, it was known that Gilenya causes a transient bradycardia (a short-lived decrease in heart rate) and might be associated with atrioventricular block (a type of heart rhythm disorder). ...

Enhancement of capillary leakage and restoration of lymphocyte egress by a chiral S1P(1) antagonist in vivo
Sphingosine 1-phosphate (S1P, 1) regulates vascular barrier and lymphoid development, as well as lymphocyte egress from lymphoid organs, by activating high-affinity S1P1 receptors. We used reversible chemical probes (i) to gain mechanistic insights into S1P systems organization not accessible through genetic manipulations and (ii) to investigate their potential for therapeutic modulation. Vascular (but not airway) administration of the preferred R enantiomer of an in vivo-active chiral S1P1 receptor antagonist induced loss of capillary integrity in mouse skin and lung. In contrast, the antagonist did not affect the number of constitutive blood lymphocytes. Instead, alteration of lymphocyte trafficking and phenotype required supraphysiological elevation of S1P1 tone and was reversed by the antagonist. In vivo two-photon imaging of lymph nodes confirmed requirements for obligate agonism, and the data were consistent with the presence of a stromal barrier mechanism for gating lymphocyte egress. ...
Abstract 14053: The Sphingosine 1-phosphate Receptor Agonist Fingolimod Increases Myocardial Salvage and Decreases Adverse Post...
Background: Sphingosine-1 phosphate (S1P) is a biophospholipid with antiapoptotic properties. Previous experiments suggest protective effects of S1P receptor (S1P-R) agonism against ischemia-reperfusion (I-R) injury in several organs, and also in cardiomyocyte cell culture. Fingolimod (FIN) is the only S1P-R agonist FDA-approved for clinical use in multiple sclerosis. The objective of our study was to determine if S1P-R activation by FIN during ischemia increases myocardial salvage, reduces myocardial infarction (MI) size, and mitigates left ventricular (LV) remodeling in a porcine model of I-R.. Methods: Acute MI was induced in 14 pigs by balloon occlusion of the proximal LAD for 60 min, followed by reperfusion. Animals randomly received FIN 15 minutes prior to reperfusion and then daily for the next 3 days, or saline for controls. Animals were evaluated with cardiac MRI and 3D-echo at 1 week and 1 month post MI. Histology and Western blot analysis were performed after 1 month.. Results: One ...

Chemoattractant Receptors and Lymphocyte Egress from Extralymphoid Tissue: Changing Requirements during the Course of...
Memory/effector T cells traffic efficiently through extralymphoid tissues, entering from the blood and leaving via the afferent lymph. During inflammation, T cell traffic into the affected tissue dramatically increases; however, the dynamics and mechanisms of T cell exit from inflamed tissues are poorly characterized. In this study, we show, using both a mouse and a sheep model, that large numbers of lymphocytes leave the chronically inflamed skin. Many T cells capable of producing IFN-γ and IL-17 also entered the draining afferent lymph, demonstrating that memory/effector T cells egress from sites of inflammation. Whereas efficient egress from acutely inflamed skin required lymphocyte-expressed CCR7, chronic inflammation promoted significant CCR7-independent exit as well. Lymphocyte exit at late time points of inflammation was sensitive to pertussis toxin but was only partially affected by the drug FTY720, implying the contribution of alternative chemoattractant receptors other than spingosine ...

Crosstalk between PKA and PKG controls pH‐dependent host cell egress of Toxoplasma gondii | The EMBO Journal
Toxoplasma gondii encodes three protein kinase A catalytic (PKAc1‐3) and one regulatory (PKAr) subunits to integrate cAMP‐dependent signals. Here, we show that inactive PKAc1 is maintained at the parasite pellicle by interacting with acylated PKAr. Either a conditional knockdown of PKAr or the overexpression of PKAc1 blocks parasite division. Conversely, down‐regulation of PKAc1 or stabilisation of a dominant‐negative PKAr isoform that does not bind cAMP triggers premature parasite egress from infected cells followed by serial invasion attempts leading to host cell lysis. This untimely egress depends on host cell acidification. A phosphoproteome analysis suggested the interplay between cAMP and cGMP signalling as PKAc1 inactivation changes the phosphorylation profile of a putative cGMP‐phosphodiesterase. Concordantly, inhibition of the cGMP‐dependent protein kinase G (PKG) blocks egress induced by PKAc1 inactivation or environmental acidification, while a cGMP‐phosphodiesterase ...
Translational aspects of sphingosine 1-phosphate biology - Strathprints
Sphingosine 1-phosphate (S1P) is a bioactive lipid that has both physiological and pathophysiological roles. It regulates cellular processes such as proliferation, migration, survival and differentiation and affects all organ systems. S1P not only activates S1P-specific receptors to initiate cellular signalling pathways but also directly regulates specific intracellular target proteins. The therapeutic opportunities surrounding S1P signalling are numerous and exemplified by the recent approval of FTY720 (a sphingosine analogue, Gilenya™) for the treatment of relapsing multiple sclerosis. A major focus of research is to develop small-molecule antagonists/agonists/inhibitors that are specific to the different S1P receptor subtypes and the enzymes that regulate S1P levels. This review describes fundamental aspects of S1P biology with an emphasis on the translational potential of intervention therapeutics.. ...
Cell-surface residence of sphingosine 1-phosphate receptor 1 on lymphocytes determines lymphocyte egress kinetics | JEM
The S1P-S1P1 signaling axis represents one of the most critical regulators of lymphocyte trafficking, yet little is known about the in vivo dynamics of S1P1 in response to ligand binding. Studies have identified a cyclical pattern of lymphocyte S1P1 expression: increased in lymphoid organs, decreased or absent in peripheral circulation. However, the signaling properties within this pattern, i.e., whether S1P1 surface expression is a necessary determinant of lymphoid residence, have been difficult to elucidate in the in vivo context. The diversity of GPCR signal regulation further complicates the issue. Agonist-induced internalization of GPCRs is believed to be important in a variety of signaling modalities (Hanyaloglu and von Zastrow, 2008; Marchese et al., 2008). In the case of some receptors, cells become unresponsive to agonists after a significant fraction of receptors are internalized (Vroon et al., 2006). Additionally, endocytosed receptors may carry out unique signaling functions in the ...

Studies on expression and function of sphingosine 1-phosphate receptor by Sung-Suk Chae
S1P1, a high affinity G-protein coupled receptor for bioactive lipid sphingosine 1-phosphate (S1P), regulates various cellular functions. However, little is known about the physiological roles of S1P1. To improve our understanding of the function of S1P1 in vivo, we investigated the role of S1P1 during limb development, S1P1 expression in the adult tissues, and S1P1 function in adult vasculature and angiogenesis. ^ During limb development, S1P1 is expressed in the vasculature and in mesenchymal tissues in the remodeling areas. S1P1 −/− limbs are hypervascularized and cartilage condensation was absent in the digit areas. The expression of VEGF and HIF-1α are highly elevated in S1P 1 −/− limbs. Endothelium specific S1P1 −/− limbs also exhibit same phenotype. These results indicate that impaired vascular function in S1P1 −/− limbs generates tissue hypoxia, resulting in abnormal limb development. ^ In normal adult tissues, S1P1 is ubiquitously expressed in various cell types, including
