ABSTRACT
Objective To study the alterations of CD19+CD5+CD1dhigh B, Th1 and Th17 cells in non-obese diabetic ( NOD) mice and the correlation between B10 cells and type 1 diabetes in NOD mice. Methods Flow cytometry ( FCM) was used to measure the levels of CD19+CD5+CD1dhigh B, CD19+IL-10+B, CD4+IFN-γ+Th1, CD4+IL-17+Th17 and CD4+CD25+Foxp3+T cells in NOD mice ( 4 weeks old NOD micegroup A, n=10;8 weeks old NOD micegroup B, n=10; NOD mice with diabetes group C, n=10) and age-matched C57BL/6 mice ( control group, n=20 ) .Hematoxylin-eosin staining of pancreatic tissues was performed for histopathological assessment of the development of insulitis in NOD mice.Results (1) Histopathological analysis showed that mice from A, B and C groups respectively showed no insulitis, insulitis and obvious insulitis with no intact islets.(2) The highest levels of B10 cells in NOD mice were ob-served in group B, followed by those in group C and group A (P0.05).More B10 cells were detected in pancreatic lymph nodes than in other tissues of 8 weeks old NOD mice, the levels of which were also higher than those in pancreatic lymph nodes of mice form group C ( P0.05).Conclusion The percentages and distribution of B10 cells in NOD mice changed with age and the development of insulitis.The decrease of B10 cells might participate in the development of type 1 diabe-tes in NOD mice.
