Project description:Yapo2017- cAMP/PKA signalling in D1 dopamine receptor expressing medium-spiny neurons This model is described in the article: Detection of phasic dopamine by D1 and D2 striatal medium spiny neurons. Yapo C, Nair AG, Clement L, Castro LR, Hellgren Kotaleski J, Vincent P. J. Physiol. (Lond.) 2017 Aug; : Abstract: The phasic release of dopamine in the striatum determines various aspects of reward and action selection, but the dynamics of dopamine effect on intracellular signalling remains poorly understood. We used genetically-encoded FRET biosensors in striatal brain slices to quantify the effect of transient dopamine on cAMP or PKA-dependent phosphorylation level, and computational modelling to further explore the dynamics of this signalling pathway. Medium-sized spiny neurons (MSNs), which express either D1 or D2 dopamine receptors, responded to dopamine by an increase or a decrease in cAMP, respectively. Transient dopamine showed similar sub-micromolar efficacies on cAMP in both D1 and D2 MSNs, thus challenging the commonly accepted notion that dopamine efficacy is much higher on D2 than on D1 receptors. However, in D2 MSNs, the large decrease in cAMP level triggered by transient dopamine did not translate in a decrease in PKA-dependent phosphorylation level, owing to the efficient inhibition of Protein Phosphatase 1 by DARPP-32. Simulations further suggested that D2 MSNs can also operate in a "tone-sensing" mode, allowing them to detect transient dips in basal dopamine. Overall, our results show that D2 MSNs may sense much more complex patterns of dopamine than previously thought. This article is protected by copyright. All rights reserved.
