The study of the content of cerebrosides, gangliosides and their hydrolytic degradation product--sphingosine in the rat brain with experimental edema was carried out. In parallel, the cytokine profile of pro- and anti-inflammatory cytokines in the blood of rats with experimental cerebral edema was
Pulmonary edema (PE) is a major cause of pulmonary manifestations of severe Plasmodium falciparum malaria and is usually associated with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). The sphingosine kinase-1 (SphK-1)/sphingosine-1-phosphate receptor-3 (S1PR-3)
Systemic exacerbation of allergic responses, in which mast cells play a critical role, results in life-threatening anaphylactic shock. Sphingosine-1-phosphate (S1P), a ligand for a family of G protein-coupled receptors, is a new addition to the repertoire of bioactive lipids secreted by activated
OBJECTIVE
To determine the effect of sphingosine-1-phosphate receptor 2 (S1PR2) on vascular permeability in mice.
METHODS
Acute lung injury models of mice were constructed with intra-tracheal administration of lipopolysaccharide (LPS) and compared with the controls with intra-tracheal administration
Endothelial sphingosine-1-phosphate receptors are emerging as relevant therapeutic targets during acute ischemic stroke (AIS). Physiologically, the cerebrovascular endothelium plays a vital role in maintaining barrier integrity and cerebrovascular homeostasis. During a cerebral ischemic event,
Lymphocyte exit from lymph nodes and their recirculation into blood is controlled by the sphingolipid sphingosine 1-phosphate (S1P). The cellular receptor mediating lymphocyte exit is S1P(1), one of five S1P receptors. Nonselective agonists for S1P receptors lead to blood lymphocyte count reduction.
Forsythiae Fructus is an important Chinese medicine which shows a significant effect against inflammation. This study aimed to investigate the preventive anti-inflammation mechanism of Forsythiae Fructus by serum metabolomics strategy and compare the difference of the metabolism pathways between
BACKGROUND
Acute lung injury and acute respiratory distress syndrome (ALI/ARDS) is a severe clinical syndrome with mortality rate as high as 30-40%. There is no treatment yet to improve pulmonary endothelial barrier function in patients with severe pulmonary edema. Developing therapies to protect
The aim of this study is to determine the anti-inflammatory activity of a new sphingosine derivative (1) and cembrenoid diterpene (lobohedleolide) (2) isolated from the soft corals of Sinularia crassa and Lobophytum species respectively, collected on the coasts of Andaman and Nicobar Islands. The
BACKGROUND
Little is known about the contribution of bone marrow-derived progenitor cells (BMPCs) in the regulation endothelial barrier function as defined by microvascular permeability alterations at the level of adherens junctions (AJs).
OBJECTIVE
We investigated the role of BMPCs in annealing AJs
OBJECTIVE
To determine the sequence of cardiovascular and blood gas changes induced by ingestion of fumonisin-containing culture material in swine and to examine the temporal relationship of these changes to plasma sphinganine and sphingosine concentrations.
METHODS
12 healthy castrated pigs (38 to
The endothelial cell (EC) barrier disruption has been implicated in vascular leakage and pulmonary edema. Many reports have shown that the EC barrier dysfunction is regulated by the sphingosine-1-phophate (S1P)/S1P receptor-1 (S1PR1) axis. Identifying downstream effectors for the S1P/S1PR1 axis in
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
BACKGROUND
Although sphingosine 1-phosphate (S1P) receptor activation by FTY720 (fingolimod) has been suggested to improve the prognosis of experimental stroke, the effect of the drug in early brain injury (EBI) after subarachnoid hemorrhage (SAH) and the precise mechanism of the effect are
Sphingosine-1-phosphate (S1P) is emerging as a hypoxia responsive bio-lipid; systemically raised levels of S1P are proposed to have potential hypoxia pre-conditioning effects. The study aims to evaluate the hypoxia pre-conditioning efficacy of exogenously administered S1P in rats exposed to acute
