c24:1 3'-sulfo galactosylceramide (d18:1/24:1)

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.

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.
