Abstract:
Objective:To investigate the Foxp3 expression in murine model of type 1 diabetes mellitus and the effects of Foxp3 in the pathogenic mechanism of type 1 diabetes mellitus.Methods:Type 1 diabetes mellitus of mouse was induced by STZ.The Foxp3 expression in the spleen cells was detected at the mRNA level by RT-PCR and at protein level by Western blot.The percentage of CD4+CD25+ Treg cells in the spleens were detected by Flow cytometry.Results:The expressing levels of Foxp3 mRNA and scurfin in the model group was higher than those of control group within the first week after induction,but the expressing level of Foxp3 mRNA and Scurfin began to decrease on day 7 and were lower than those of control group on day 30.The percentage of CD4+CD25+ Treg cells in model group was similar with that of control group within the first week after induction,but after day 7,the percentage of CD4+CD25+ Treg cells in model group began to get lower than contol group.Conclusion:The expressing level of Foxp3 is decreased,then the proportion of CD4+CD25+ Treg cells is decreased accordingly,which may contribute to the pathogenic mechanism in type 1 diabetes mellitus.
