c24 3'-sulfo galactosylceramide

Tetracosanoyl-sulfatide is an endogenous sulfated glycolipid, which are also known as sulfatides . Tetracosanoyl-sulfatide is the major sulfatide in mature myelin in the central and peripheral nervous systems. Levels of Tetracosanoyl-sulfatide are elevated in plasma derived from patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency, leading to sulfatide accumulation. Unlike C24:1 3'-sulfo galactosylceramide, it does not induce an immune response in mouse splenocytes in vitro.

C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z)) is the predominant sulfate analog in the mature myelin sheath. C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z)) interacted with C-type lectin and immunoglobulin-like receptors to give the highest affinity for LMIR5. Galactosylceramide (d18:1 24:1(15Z)) induces MCP-1 production by basophils, which activates NFAT by increasing LMIR5, but not mast cells .C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z)) binds in vitro to CD1d binding and increased the proliferation of free mouse splenocytes.

Sulfatides are endogenous sulfoglycolipids with various biological activities in the central and peripheral nervous systems, pancreas, and immune system. They are produced from the combination of ceramide and UDP-galactose in the endoplasmic reticulum followed by sulfation in the Golgi apparatus. The ceramide portion contains variable fatty acid chain lengths, which are tissue- and pathology-dependent. Sulfatides are primarily found in the myelin sheath of oligodendrocytes and Schwann cells, with smaller chain lengths predominant during development and longer chain lengths predominant in mature cells. They accumulate in the lysosome of patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency. Sulfatides are also located in pancreatic β-cells and inhibit insulin release from isolated rat pancreatic islet cells, suggesting a potential role in diabetes. Sulfatides can induce inflammation in glia in vitro and certain sulfatides, such as C24:1 3'-sulfo-galactosylceramide, can induce an immune response in vitro in mouse splenocytes. Sulfatides (bovine) (sodium salt) is a mixture of isolated bovine sulfatides.
