1 Protein kinase G linked to dopamine D3 receptors in the dorsal striatum controls dopamine release, DeltaFosB expression and locomotor activity after repeated cocaine administration. Cocaine protein kinase cGMP-dependent 1 Homo sapiens
2 Inhibition of neuronal nitric oxide synthase, cGMP or PKG, stimulation of D3 receptors, and simultaneous inhibition of each of them with D3 receptor stimulation decreased the repeated cocaine-induced increase in dopamine concentrations and locomotor activity. Cocaine protein kinase cGMP-dependent 1 Homo sapiens
3 Similarly, inhibition of PKG and simultaneous inhibition of PKG with D3 receptor stimulation decreased DeltaFosB immunoreactivity elevated by repeated cocaine administration, however stimulation of D3 receptors alone did not. Cocaine protein kinase cGMP-dependent 1 Homo sapiens
4 Similarly, inhibition of PKG and simultaneous inhibition of PKG with D3 receptor stimulation decreased DeltaFosB immunoreactivity elevated by repeated cocaine administration, however stimulation of D3 receptors alone did not. Cocaine protein kinase cGMP-dependent 1 Homo sapiens
5 These findings suggest that activation of PKG after repeated cocaine administration is more sensitive to interact with D3 receptors in the dopamine terminals than those in medium spiny neurons. Cocaine protein kinase cGMP-dependent 1 Homo sapiens
