摘要:

通过对灌胃牛乳铁素(LfcinB)后小鼠血清中细胞因子IL-2、IL-4、IL-6、IL-10 和TNF-α水平的变化,评价其免疫调节作用。结果表明,灌胃牛乳铁素后3h 采血,分离其血清,用ELISA 试剂盒检测细胞因子,与阴性对照组相比,对细胞因子IL-2 和TNF- α产生极显著促进作用(P ≤ 0.01),对抗炎细胞因子IL-4 有极显著的抑制作用(P ≤ 0.01),对IL-6 有显著的抑制作用(P ≤ 0.05),对抗炎细胞因子IL-10 的分泌影响也极显著(P ≤ 0.01),并且IL-10 随TNF-α的增强而增强,起到平衡作用。因此,口服牛乳铁素对实验小鼠具有免疫增强和调节作用。

Abstract:

In order to figure out whether bovine lactoferricin (LfcinB) has immuno-regulation function, cytokines such as IL-2, IL-4, IL-6, IL-10 and TNF-α in blood sera from mice orally administered with LfcinB were tested using ELISA kits. The results indicated that IL-2 and TNF-α levels in lactoferricin treatment mice at 3 h post-administration were both even higher (P ≤ 0.01) than those in negative control mice, whereas the levels of anti-inflammatory cytokines, IL-4 (P ≤ 0.01) and IL-6 (P ≤0.05) revealed a significant decrease, and IL-10 level which is positively correlated with TNF-α level and plays a balancing role also changed notably. Therefore, oral administration of lactoferricin has the potential to provide the function of immune enhancement and regulation.

Key words: lactoferricin, cytokine, immuno-regulation function
