alpha-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。

α-Galactosylceramide analog 8 (α-GalCer analog 8) is a triazole derivative of α-galactosylceramide. [1] It increases IL-2 secretion by DN32.D3 NKT hybridoma cells when co-cultured with CD1d-transfected RBL cells pre-loaded with α-GalCer analog 8 at a concentration of 32 ng ml. α-GalCer analog 8 (32 ng ml) induces IL-4 secretion to a greater extent than the synthetic α-GalCer KRN 7000 in mouse splenocytes in vitro and in mouse serum following administration of a 1 µg per animal dose, indicating a Th2 response.
