Pituitary adenylate cyclase-activating polypeptides (PACAP-27 and PACAP-38) are neuropeptides of the vasoactive intestinal polypeptide (VIP)/secretin/glucagon family. PACAP receptors are expressed in different brain regions, including cerebellum. We used primary culture of rat cerebellar granule neurons to study the effect of PACAP-38 on apoptosis induced by potassium deprivation. We demonstrated that PACAP-38 increased survival of cerebellar neurons in a dose-dependent manner by decreasing the extent of apoptosis estimated by DNA fragmentation. PACAP-38 induced activation of the extracellular signal-regulated kinase (ERK)-type of mitogen-activated protein (MAP) kinase through a cAMP-dependent pathway. PD98059, an inhibitor of MEK (MAP kinase kinase), completely abolished the antiapoptotic effect of PACAP-38, suggesting that MAP kinase pathway activation is necessary for PACAP-38 action.
