Abstrakt     Synaptotagmins (Syts) I and IV are synaptic proteins involved in the regulation of neurosecretion. Dopaminergic drugs have been shown to modulate their expression. Here we investigate whether dopaminergic regulation of syt I and syt IV expression could play a role in the hypersensitive striatum of rats with unilateral lesions of dopaminergic nigrostriatal neurons with 6hydroxydopamine. We show that chronic dopaminergic denervation resulted in a small down-regulation of striatal syt I mRNA whereas acute treatment with SKF-82958, a dopamine DI receptor agonist, induced a massive syt IV mRNA upregulation in the striatum on the lesioned side. We conclude that chronic lack of dopamine and treatment with dopamine depleted basal ganglia.
