Abstract:
Objective:To study relationship between B10 cells and the incidence of autoimmune diabetes in nonobese diabetic mice. Methods:20 NOD/LT female mice of 6 week old were cultured in normal culture to 30 weeks,and the mice were divided into two groups according the mice’s blood glucose,serum creatinine and body weight detected at their 30 weeks old. IL-10 levels in spleen tissues of the two groups were detected by enzyme-linked immunosorbent assay. We used flow cytometry to detect the proportion of B10 cells in the spleen of mice in the two groups. NOD/LT mice were randomly divided into control group and B10 group. The B10 cells were inoculated in B10 groups,their blood glucose were detected when they were 10,15,20,25 and 30 weeks old. Results: The blood glucose and serum creatinine levels were significantly higher in the group than that in the autoimmune diabetes group (P< 0. 05),and the body weight was significantly lower than that in the autoimmune diabetes group (P<0. 05). The level of IL-10 in the spleen tissues of the autoimmune diabetes mice was significantly higher than that in the non autoimmune diabetes group. The content of B10 cells in the spleen of the mice with autoimmune diabetes mellitus was significantly higher than that in the non autoimmune diabetes group. When mice at the age of 10,15 weeks,the incidence of autoimmune diabetes in B10 group was significantly lower than that in the control group,but the incidence of autoimmune diabetes in B10 group was significantly higher than that in control group at 20,25 and 30 weeks. Conclusion:The over accumulation of B10 cells may be one of the reasons for the further development of autoimmune diabetes in NOD mice.
