Abstract: Incubation of synaptosomes from rat brain with dl-2-amino-5-phosphonovalerate (APV) stimulated an increased release of dopamine, and this effect was strictly dependent on the extrasynaptosomal calcium level. APV increased biosynthesis of dopamine from tyrosine by 30%, whereas monoamine oxidase activity was inhibited by 30%. When synaptosomes were incubated with radioactive dopamine, APV caused a large decrease in incorporation of label into 3,4-dihydroxyphenylacetic acid but greatly increased incorporation into norepinephrine and its N-methyl derivatives.
Abstract: This study presents experimental evidence for the mediation of a behavioral effect of phencyclidine-like drugs by inhibition of neurotransmission at excitatory synapses utilizing N-methyl-aspartate (NMA) receptors by showing that -2-amino-5-phosphonovalerate, a selective NMA antagonist, produces phencyclidine-like catalepsy in pigeons. This finding suggests the possibility that other behavioral actions of phencyclidine-like substances may be mediated in a similar fashion.
We previously showed that the associative enhancement ofAplysia siphon sensorimotor synapses in a cellular analog of classical conditioning is disrupted by infusing the Ca2+ chelator 1,2-bis(2-aminophenoxy)ethane-N,N-N',N'-tetraacetic acid into the postsynaptic motor neuron before training or by training in the presence of the NMDA receptor antagonistdl-2-amino-5-phosphonovalerate (APV). Our earlier experiments with APV used a nondifferential training protocol, in which different preparations were used for associative and nonassociative training.
