Activation of glutamate ionotropic receptors represents the primary event in the neurotoxicity process triggered by excitatory amino acids. We demonstrate here that the concentration-dependent stimulation of metabotropic receptor by the selective agonist trans-1-aminocyclopentane-1,3-dicarboxylate (tACPD) counteracts the glutamate-induced neurotoxicity in primary culture of rat cerebellar granule cells. The metabotropic receptor-evoked responses are potentiated by aniracetam, which per se also elicits neuroprotection.

Abstract
Activation of glutamate ionotropic receptors represents the primary event in the neurotoxicity process triggered by excitatory amino acids. We demonstrate here that the concentration-dependent stimulation of metabotropic receptor by the selective agonist trans-1-aminocyclopentane-1,3-dicarboxylate (tACPD) counteracts the glutamate-induced neurotoxicity in primary culture of rat cerebellar granule cells. The metabotropic receptor-evoked responses are potentiated by aniracetam, which per se also elicits neuroprotection.File in questo prodotto:
