7. boosting dopamine signaling in the striatum by acute cocaine administration reveals that absence of D2L, but not of D2S, strongly impairs the motor and cellular response to the drug, in a manner similar to the ablation of both isoforms. These results suggest that when the dopamine system is challenged, D2L signaling is required for the control of striatal circuits regulating motor activity. PMID: 29255027

10. 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

In humans, dopamine also modulates b cell mass through DRD2 and exerts an inhibitory effect on adenosine signaling PMID: 27373926
17. The expression of Klf15 is increased during neuropathic pain. TNF-alpha regulates the expression of Klf15. KLF15 regulates the expression of dopamine D2 receptor. KLF15 regulates neuropathic pain in mouse models. PMID: 28830816

20. Study found no differences in the D2R binding following ten-day methamphetamine administration and seven-day withdrawal, possibly suggesting that alterations in the D2R are not involved in the emergence of anxiety-related symptoms and the development of psychomotor sensitization during withdrawal PMID: 26896754
21. Dopamine Receptor Signaling in MIN6 beta-Cells PMID: 27508444
22. Results suggest that the role of reduced D2 receptor in obesity lies not in increasing appetitive motivation and generating compulsive eating but rather in altering activity and energy expenditure, favoring reduced behavioral expenditure of energy. More broadly, these data are consistent with a fundamental role for dopamine in regulating behavioral energy expenditure. PMID: 26281715
23. D2R agonist treatment blocks tumor growth, induces regression of the aberrant blood supply and normalizes blood vessels. An anti-Vegf therapy is also effective to restrain tumor growth and improves vascular remodeling. Importantly, only the combination treatment suppresses intratumoral hemorrhage and restores blood vessel perfusion, suggesting that it might represent an attractive therapy targeting tumor vasculature PMID: 28152577
24. These results suggest that DRD2 activation is involved in alleviation of CIA symptoms by amelioration of Th17/Treg imbalance. PMID: 26693483
