C24:1 3'-sulfo Galactosylceramide (d18:1/24:1(15Z)) Chemical Properties,Usage,Production

Description

C24:1 3’-sulfo Galactosylceramide is a member of the sulfatide class of glycolipids. It is the predominate sulfatide species in mature myelin, and it accumulates at a higher rate than C24 3’-sulfo galactosylceramide in rat cerebellum from seven to 32 days of age when active myelination occurs.¹ It interacts with C-type lectins and immunoglobulin-like receptors with the highest affinity for LMIR5.² It induces production of MCP-1 in basophils but not mast cells and increases the activation of NFAT in a reporter assay via LMIR5. C24:1 3’-sulfo Galactosylceramide is an immunodominant species in myelin, is bound by CD1d in vitro, and increases proliferation in isolated mouse splenocytes.³ It reduces symptoms and increases survival in a mouse model of chronic relapsing-remitting experimental autoimmune encephalomyelitis (EAE) when used at a dose of 20 μg.⁴ It also decreases the number of inflammatory lesions and infiltrating mononuclear cells in the lumbar spinal cord of EAE mice. As this product is derived from a natural source, there may be variations in the sphingoid backbone.

Definition

ChEBI: 1-(3-O-sulfo-beta-D-galactosyl)-N-[(15Z)-tetracos-15-enoyl]sphingosine is an N-acyl-beta-D-galactosylsphingosine having a sulfo group at the 3-position on the galactose ring and (15Z)-tetracos-15-enoyl as the N-acyl group. It has a role as an epitope. It is a galactosylceramide sulfate and a N-acyl-beta-D-galactosylsphingosine. It is a conjugate acid of a 1-(3-O-sulfo-beta-D-galactosyl)-N-[(15Z)-tetracos-15-enoyl]sphingosine(1-).
