title: Vasoactive intestinal polypeptide increases inositol phospholipid breakdown in the rat superior cervical ganglion.
abstract: The effects of VIP and of peptides of the VIP family: secretin, glucagon, the porcine histidine isoleucine containing peptide (PHI) and the rat hypothalamic growth hormone-releasing hormone (rhGRF) on the cyclic AMP and inositol phosphate contents of isolated rat superior cervical ganglia were investigated. We demonstrate that VIP is able to provoke a large inositol lipid breakdown by acting directly on ganglionic cells. This observation suggests the presence in rat superior cervical ganglia of a new type of receptors for VIP or for an unidentified peptide structurally related to VIP.
