  • Title: Neuroprotection: a comparative view of vasoactive intestinal peptide and pituitary adenylate cyclase-activating polypeptide.
    Author: Brenneman DE.
    Journal: Peptides; 2007 Sep; 28(9):1720-6. PubMed ID: 17513014.
    Abstract:
    The neuroprotective properties of vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) place these peptides in a special category of ligands that have implications for our understanding of pathological conditions as well as a potential basis for therapeutic intervention. It is remarkable that these peptides have a protective impact against such a wide variety of clinical relevant toxic substances. This protective diversity is consistent with the multiple pathways that are activated or inhibited by the action of these peptides. Although knowledge is emerging on the neuroprotective mechanisms of VIP and PACAP, it is already evident that these two peptides are not identical in their action and each peptide has multiple mechanisms that allow for neuroprotective diversity. The multiple intracellular signaling pathways and differing extracellular mediators of neuroprotection contribute to this diversity of action. In this review, examples of neuroprotective actions will be presented that serve to demonstrate the remarkable breadth of neuroprotective processes produced by VIP and PACAP.
