Sphingosine-1-phosphate receptor inhibition prevents denervation-induced dendritic atrophy
A hallmark of several major neurological diseases is neuronal cell death. In addition to this primary pathology, secondary injury is seen in connected brain regions in which neurons not directly affected by the disease are denervated. These transneuronal effects on the network contribute considerably to the clinical symptoms. Since denervated neurons are viable, they are attractive targets for ...
متن کاملSphingosine-1-phosphate prevents permeability increases via activation of endothelial sphingosine-1-phosphate receptor 1 in rat venules.
Sphingosine-1-phosphate (S1P) has been demonstrated to enhance endothelial barrier function in vivo and in vitro. However, different S1P receptor subtypes have been indicated to play different or even opposing roles in the regulation of vascular barrier function. This study aims to differentiate the roles of endogenous endothelial S1P subtype receptors in the regulation of permeability in intac...
متن کاملSphingosine-1-phosphate prevents chemotherapy-induced human primordial follicle death.
STUDY QUESTION Can Sphingosine-1-phosphate (S1P), a ceramide-induced death pathway inhibitor, prevent cyclophosphamide (Cy) or doxorubicin (Doxo) induced apoptotic follicle death in human ovarian xenografts? SUMMARY ANSWER S1P can block human apoptotic follicle death induced by both drugs, which have differing mechanisms of cytotoxicity. WHAT IS KNOWN ALREADY S1P has been shown to decrease ...
متن کاملNeurobiological effects of sphingosine 1-phosphate receptor modulation in the cuprizone model.
Fingolimod (FTY720) is a sphingosine 1-phosphate (S1P) receptor modulator that regulates lymphocyte trafficking and exerts pleiotropic actions on oligodendrocytes (OLGs) and other neural cells. The purpose of this study was to investigate the role of S1P receptors in a non-T-cell model of demyelination, the cuprizone (cupr) model in C57BL/6 mice. Treatment with FTY720 (1 mg/kg) led to attenuate...
