Interestingly, curcumin imparted immunosuppression by mainly down-regulating the expression of CD28 and CD80 and up-regulating CTLA-4.

We have used an inducible diabetes model based on rat insulin promotor (RIP)-driven expression of CD80 (B7-1) on pancreatic beta cells.

Earlier, we demonstrated that CD80 binds to CTLA-4 with higher affinity and has a role in suppressing T cell response.

Induction of TGF-beta1(+) and IL-10(+) T cells was found to be independent of natural CD4(+)CD25(+) regulatory T cells, demonstrating that preferential ligation of CTLA-4 by CD80 induced IL-10 production by effector T cells, which in turn promoted the secretion of TGF-beta1.

These observations demonstrate not only that CD80 preferentially binds to CTLA-4 but also that interaction during Ag presentation can result in IL-10-dependent TGF-beta1(+) regulatory T cell induction, reinstating the potential of approaches to preferentially engage CTLA-4 through CD80 during self-Ag presentation in suppressing autoimmunity.

The BMDCs from NOD mice displayed reduced mRNA expressions of NF-kappaB components, p65, p50, p52, and RelB, compared to NON mice: the proportions of each molecule relative to those of NON DCs were 53.9, 54.1, 54.0, and 37.0%, respectively, which were accompanied with lowered expressions of downstream immunomodulatory molecules, including IL-6, CD80, CD86, 4-1BB, and CD40.

Furthermore, ectopic expression of CD80 by beta cells accelerated the onset of insulitis mediated by beta-cell-specific CD8(+) T cells, but had no effect on CD4(+) T-cell-mediated diabetes, suggesting an antigenic interaction between beta cells and naive CD8(+) T cells.

CD11c(+) subtypes downregulated IL-1beta and genes mediating antigen presentation (I-a, CD80) and upregulated the M2 hallmark Ym-1 and genes promoting oxidative metabolism (PGC-1alpha) and adipogenesis (MMP-2).

RIP-B7.1 mice expressing the costimulator molecule B7.1 (CD80) on pancreatic beta-cells are a well established model to characterize preproinsulin-specific CD8 T-cell responses and experimental autoimmune diabetes (EAD).

The results of human umbilical cord blood monocyte-derived DC-GAD(35) autoantigen incubation experiments showed that inoculation of immature DCs (iDCs), with CTB-GAD(35) protein dramatically suppressed levels of CD86, CD83, CD80 and CD40 co-stimulatory factor protein biosynthesis in comparison with GAD(35) alone inoculated iDCs.
