The Neuropeptide Vasoactive Intestinal Peptide Generates Tolerogenic Dendritic Cells

The neuropeptide vasoactive intestinal peptide generates tolerogenic dendritic cells.

Tolerogenic dendritic cells (DCs) play an important role in maintaining peripheral tolerance through the induction/activation of regulatory T cells (Treg). Endogenous factors contribute to the functional development of tolerogenic DCs. In this report, we present evidence that two known immunosuppressive neuropeptides, the vasoactive intestinal peptide (VIP) and the pituitary adenylate cyclase-a...

Vasoactive intestinal peptide generates human tolerogenic dendritic cells that induce CD4 and CD8 regulatory T cells.

Induction of antigen-specific tolerance is critical for autoimmunity prevention and immune tolerance maintenance. In addition to their classical role as sentinels of the immune response, dendritic cells (DCs) play important roles in maintaining peripheral tolerance through the induction/activation of regulatory T (T(reg)) cells. The possibility of generating tolerogenic DCs opens new therapeuti...

Protein kinase C inhibitor generates stable human tolerogenic dendritic cells.

Tolerogenic dendritic cells (DCs) are a promising tool for a specific form of cellular therapy whereby immunological tolerance can be induced in the context of transplantation and autoimmunity. From libraries of bioactive lipids, nuclear receptor ligands, and kinase inhibitors, we screened conventional protein kinase C inhibitors (PKCIs) bisindolylmaleimide I, Gö6983, and Ro32-0432 with strong ...

Vasoactive intestinal peptide (VIP).

In 1969, Said and Mutt reported the extraction from secretion, increased flow of alkaline pancreatic normal lung tissue of a peptide which was capable juice and small intestinal juice with increased cyclic of causing gradual but prolonged peripheral AMP content (Makhlouf and Said, 1975), overlap vasodilation. This finding led them to search for markedly with the actions of the other three pepti...
