目的:观察胰岛素样生长因子-1(IGF-1)对T,B细胞分泌功能的影响,以探究IGF-1治疗应激机体免疫功能低下的可能性.方法:用酶联免疫吸附试验(ELISA)分析体外免疫应答中IGF-1对小鼠T细胞分泌白介素-2(IL-2)和B细胞分泌免疫球蛋白(Ig)的影响.结果:小鼠T,B细胞在给予80μg/L IGF-1的条件下培养3 d,其上清的IL-2活性比对照组增加了366.74 nkat/mL(P<0.01),培养6 d后正常小鼠T,B细胞培养上清和应激小鼠T,B细胞培养上清中的IgG含量均比对照组高,尤其是应激小鼠T,B细胞培养上清的IgG含量比对照组增加了41μg/L(P<0.01).结论:抗原刺激后的小鼠T,B细胞进行体外培养时,在IGF-1存在下T细胞分泌IL-2和B细胞分泌IgG的能力增强,提示IGF-1对机体的免疫应答有调节作用.
Effect of IGF-I on secretory function of mouse T,B lymphocytes
AIM: To explore the possibility of the IGF-1 treatment on immune dysfunction in stressed situation, the insulin-like growth factor-1 (IGF-1) on the effect of T, B cell secretory function was observed. METHODS: Using enzymelinked immunosorbent assay(ELISA) analyzed the effect of IGF-1 on mouse T cell secretion of interleukin-2 (IL-2) and B cells secretion of immunoglobulin(Ig) in immune response to antigen in vitro. RESULTS: Mice T, B cells administrated 80 g/L IGF-1 were cultured for 3 d, the IL-2 activity in culture supernatant increased 366.74 nkat/mL as compared with the control group (P < 0.01), and that were cultured for 6 d the IgG content in normal mice T, B cells culture supernatant and stressed mice T, B cells culture supernatant were higher separately than that control group. Especially the IgG content in stressed mice T, B cells culture supernatant increased 41 μg/L as compared with the control group(P < 0.01). CONCLUSION: In the presence of IGF-1 the mouse T, B cell stimulated by antigen cultured in vitro, the ability of T cells secreted IL-2 and B cell secreted IgG were enhanced. It is suggest that IGF-1 may have a modulatory effect on the immune response.
