ABSTRACT
Objective:
To illuminate the influence of InsB15-23 H-2Kd dtSCT to the morbidity of type 1 diabetes mellitus in NOD mice.Methods:
An eukaryotic plasmid encoded membrane-expressed InsB15-23 H-2Kd dtSCT was inoculated into 3 weeks old female NOD mice subcutaneously and the blood sugar and morbidity of type 1 diabetes mellitus were monitored once a week.To illuminate the cellular mechanism of immunologic intervention of membrane-expressed InsB15-23 H-2Kd dtSCT to the course of type 1 diabetes mellitus in NOD mice,the mononuclear cell infiltration of islets was detected by tissue slice and the frequency of IGRP206 2-14 specific CTLs in PBMC was analyzed by FACs.Results:
As compared with pcDNA3.1 (-) control ( 60%) and untreated NOD mice ( 80%) , mice immunized with InsB15-23 H-2Kd dtSCT exhibited low level of islet infiltration and low morbidity in 30 weeks old ( 9%) .But the frequency of IGRP206-214 specific CTLs in PBMC of 16 and 40 weeks old mice showed no difference.Conclusion:
Membrane-expressed InsB15-23 H-2Kd dtSCT can protect NOD mice from type 1 diabetes mellitus in IGRP206-214 independent pattern.
