Abstract：
:The signal transduction pathways involved in NMDA receptor modulation by other receptors remain unclear. cAMP could be involved in this modulation. The aim of this work was to analyse the contribution of cAMP to NMDA receptor modulation in cerebellar neurones in culture. Forskolin increases cAMP and results in increased intracellular calcium and cGMP that are prevented by blocking NMDA receptors. Similar effects were induced by two cAMP analogues, indicating that cAMP leads to NMDA receptor activation. It has been reported that phosphorylation of Ser897 of the NR1 subunit of NMDA receptors by cAMP-dependent protein kinase (PKA) activates the receptors. Forskolin increases Ser897 phosphorylation. Neither Ser897 phosphorylation nor cGMP increase induced by forskolin are prevented by four inhibitors of PKA, suggesting that NMDA receptor activation is dependent on cAMP but not on PKA. Inhibition of Akt prevents forskolin-induced phosphorylation of Ser897, suggesting a role for Akt in the mediation of the modulation of NMDA receptors by cAMP. Pituitary adenylate cyclase-activating polypeptide (PACAP) activates its receptors, increasing cAMP and also leading to phosphorylation of Ser897 of NR1 and activation of NMDA receptors. These results indicate that cAMP modulates NMDA receptor in cerebellar neurones and may play a role in NMDA receptor modulation by other receptors.
