PACAP Stimulates Biosynthesis and Release of Endozepines from Rat Astrocytes
Abstract : Astrocytes synthesize and release endozepines, a family of neuropeptides related to diazepam-binding inhibitor (DBI). Astroglial cells also express the receptors of pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP). In the present article, we show that PACAP dose dependently increases DBI gene expression and stimulates endozepine release through activation of PAC1-R. PACAP increases cAMP formation, enhances polyphosphoinositide turnover, and evokes calcium mobilization from intracellular Ca2+ pools. The effect of PACAP on endozepine release is mediated through the adenylyl cyclase/PKA pathway while the downregulation of astrocyte response to PACAP can be ascribed to activation of the PLC/PKC pathway.
