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.

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.

C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z))是成熟髓鞘中主要的硫酸盐类化合物。C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z)) 在大鼠小脑中发现活跃的髓发生鞘化反应时积累率高于C24 3'-sulfo 半乳糖甘油酰胺。C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z))与C 型凝集素和免疫球蛋白样受体相互作用使对LMIR5的亲和力高。C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z))诱导嗜碱细胞产生MCP-1，可通过增加LMIR5激活NFAT，但不能诱导肥大细胞 。C24:1 3'-sulfo Galactosylceramide (d18:1 24:1(15Z))在体外与CD1d 结合，并增加游离小鼠脾细胞的增殖。
