VIP and tolerance induction in autoimmunity
Vasoactive intestinal peptide (VIP) is a potent antiinflammatory agent with immunoregulatory properties, skewing the immune response to a Th2 pattern of cytokine production. Here, we studied the effect of treatment with VIP in the development of diabetes in nonobese diabetic (NOD) mice, an annual mo...

Here, we studied the effect of treatment with VIP in the development of diabetes in nonobese diabetic (NOD) mice, an annual model of type 1 diabetes. Mice treated with VIP from 4 weeks of age did not develop diabetes and showed milder insulitis than nontreated mice. The protective mechanism of VIP was associated with a reduction in the circulating levels of Th1 cytokines. In the pancreas of VIP-treated animals, regulatory T cell markers predominate, as indicated by the upregulation of FoxP3 and transforming growth factor-β (TGF-β), and the downregulation of the transcription factor, T-bet. These findings indicate that VIP restores tolerance to pancreatic islets by promoting the local differentiation and function of regulatory T cells. © 2006 New York Academy of Sciences.
