Description
We identified DCIR2+DCs but not DEC205+DCs as able to induce peripheral T cell tolerance in pre-diabetic autoimmune NOD mice. To determine what distinct genetic programs are elicited in the auto-reactive CD4 T cells early after stimulation by these two DC subsets, we utilized adoptive transfer of BDC2.5 CD4 T cells into NOD mice, which were then given chimeric antibody to deliver the beta-cell specific antigen to either DCIR2+DCs or DEC205+DCs, leading to BDC2.5 CD4 T cell specific stimulation in vivo. The analysis shows that the negative transcriptional factor Zbtb32 (ROG) is up-regulated more in BDC2.5 CD4 T cells after stimulated with a antigen via DCIR2+DCs presentation, compared with DEC205+DCs, suggesting the involvement of Zbtb32 in DCIR2+DCs-mediated auto-reactive T cell tolerance in disease ongoing NOD mice.
