Actions of vasoactive intestinal peptide and neuropeptide Y on the pacemaker current in canine Purkinje fibers.
We have investigated the actions of vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) on the pacemaker current (I(f)) in canine Purkinje fibers. On voltage pulses to the middle of the I(f) activation range, VIP reversibly increases I(f), whereas NPY reversibly decreases I(f). A three-pulse voltage protocol suggests that VIP shifts I(f) activation in the positive direction and that NP...
متن کاملThe 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...
متن کاملAn immunohistochemical study of vasoactive intestinal peptide and neuropeptide Y in the sheep pineal gland during prenatal development
In this immunohistochemical study we investigate the presence of vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) during embryonic development in the sheep pineal gland. We use ten ovine embryos at different stages of development (117 to 150 days of prenatal development). The VIP positive fibers were observed along the blood vessels, entering the pineal gland through the pineal caps...
متن کاملVasoactive intestinal peptide stimulates neuropeptide Y gene expression and causes neurite extension in PC12 cells through independent mechanisms.
Vasoactive intestinal peptide (VIP) is widely recognized as a regulator of tyrosine hydroxylase via a mechanism of trans-synaptic activation. Subsets of adrenal medullary cells and postganglionic sympathetic nerves coexpress the peptide neurotransmitter neuropeptide Y (NPY) with catecholamines. Using PC12 cells transiently expressing a fusion gene in which the bacterial enzyme chloramphenicol a...
متن کاملVasoactive 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...
