Galactosylsphingosine (d18:1)

Galactosylsphingosine is a bioactive sphingolipid. It potentiates LPS-induced production of inflammatory cytokines, decreases the mitochondrial membrane potential, and induces cell death in mouse astrocytes, effects that can be reversed by the sphingosine-1-phosphate receptor agonist FTY720 phosphate (Cay-10008639). Galactosylsphingosine (0.1 and 1 µM) induces demyelination of mouse cerebellar slices. It inhibits PDGF-induced translocation of PKC to the cell surface and induces apoptosis in MO3.13 oligodendrocytes. Galactosylsphingosine (10 and 15 µM) inhibits gene transcription mediated by peroxisome proliferator-activated receptor alpha (PPARalpha) in reporter assays using C6 glial cells. Levels of galactosylsphingosine are increased in postmortem brain from patients with Krabbe disease, a lysosomal storage disorder characterized by a beta-galactosylceramidase deficiency.[Matreya, LLC.
