Recombinant Rat D (2) dopamine receptor (Drd2)

1. Results indicate that D2 receptors modulate [(3)H]GABA release at striatopallidal terminals by activating the PLC-->IP3-->Calcineurin-signaling cascade, the same one that modulates excitability in soma. Additionally, D2 receptors inhibit release when AC is active. Both mechanisms appear to converge to regulate the activity of presynaptic L-type Ca(2+) channels. PMID: 29292080
2. D2R knockdown in neurons whose cell bodies reside in the ventral tegmental area (VTA) shifted discounting curve to the left, indicating a preference for the smaller, immediate reward, whereas the curve for control rats remained stable and unchanged. Results demonstrate that a decrease in VTA D2Rs enhances choice impulsivity. PMID: 29287910

4. Pre- and postsynaptic colocalization of kappa opioid receptor and D2R supports a role for kappa opioid receptor potentiating both the D2R inhibitory autoreceptor function and the inhibitory action of D2R on efferent medium spiny neurons. Kappa opioid receptor co-activation accelerates D2R sensitization by contributing to decrease dopamine release in the nucleus accumbens. PMID: 28531297
5. Dopamine D2 receptor antagonism differentially affects aversive memory formation after acute or long-term sugar consumption.

16. We encountered significant differences in the effect of neonatal lesion in the ventral hippocampus on drd2 and drd3 mRNA expression levels among the brain regions analyzed in rat adulthood.
