[Pituitary adenylate cyclase activating peptide (PACAP)--its polyfunctionality in the mechanisms of brain protection].
Modern data of molecular and biological properties and physiological role of new pituitary adenylate cyclase activating polypeptide--PACAP--review. PACAP play key role in the embryogenesis of brain, in the protection of brain nerve cells from ischemia-induced death, injuring and apoptosis. New data are discussed concerned with molecular cloning and tissue distribution of receptors for PACAP, gene proPACAP expression in gastrointestinal tract, reproductive organs and nervous system. PACAP increase cytosolic free calcium and modifies the calcium-sensitive K(+)-channels, PACAP protects cultures cortical and hippocampal neurons from glutamate-induced cytotoxicity. The sleep modulation and modification of seizures activity of brain through the secretion of vasopressin or/and through NMDA receptors directly should be include in the program of PACAP "physiological continuum" of functions.
