a-galactosylceramide

α-Galactosylceramide (KRN7000) 是一种具有抗肿瘤和免疫刺激作用的合成糖脂。它是一种高效的 NKT 细胞激动剂，可与 CD1d 有效结合。它与 CD1d 的复合物可与 NKT 细胞的 T 细胞抗原受体结合。

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.

C16 3'-sulfo galactosylceramide (d18:1/16:0)是硫酸盐类糖脂的一种。C16 3'-sulfo Galactosylceramide (d18:1/16:0)是在猪脑和血浆中发现的一种比较丰富的硫化物，在小鼠的整个发育过程中会有所减少。C16 3'-sulfo Galactosylceramide (d18:1/16:0)在体外可抑制视网膜神经节细胞生长。C16 3'-sulfo Galactosylceramide (d18:1/16:0)已被用作量化大鼠小脑和多发性硬化症患者分离的白质中的硫化物的参照物。
