Role of D1/D2 dopamin receptors antagonist perphenazine in morphine analgesia and tolerance in rats

open access: yesBiomolecules & Biomedicine, 2013
While opioid receptors have been implicated in the development of tolerance, the subsequent mechanisms involved in these phenomena have not been completely understood.

Effects on turning of microinjections into basal ganglia of D1 and D2 dopamine receptors agonists and the cannabinoid CB1 antagonist SR141716A in a rat Parkinson's model

open access: yesNeurobiology of Disease, 2004
Brain cannabinoid CB1 receptors are expressed in neural areas that contribute to movement such as basal ganglia, where they co-localize with dopamine D1 and D2 receptors.

Mechanisms Underlying Dopaminergic Regulation of Nicotine-Induced Kinetic Tremor

open access: yesFrontiers in Pharmacology, 2022
Nicotine induces kinetic tremor, which resembles pharmacological features of essential tremors, via activating the inferior olive (IO) neurons. Since nicotine is known to enhance dopamine release by stimulating α4β2 and/or α6 nACh receptors, we examined ...

Dopaminergic presynaptic modulation of nigral afferents: its role in the generation of recurrent bursting in substantia nigra pars reticulata neurons

open access: yesFrontiers in Systems Neuroscience, 2011
Previous work has shown the functions associated with activation of dopamine presynaptic receptors in some substantia nigra pars reticulata (SNr) afferents: i) striatonigral terminals (direct pathway) posses presynaptic dopamine D1-class receptors whose ...

Evidence against dopamine D1/D2 receptor heteromers [PDF]

open access: yesMolecular Psychiatry, 2015
Hetero-oligomers of G-protein-coupled receptors have become the subject of intense investigation, because their purported potential to manifest signaling and pharmacological properties that differ from the component receptors makes them highly attractive for the development of more selective pharmacological treatments. In particular, dopamine D1 and D2

Dopamine D1 and D2 receptor immunoreactivities in the arcuate-median eminence complex and their link to the tubero-infundibular dopamine neurons

open access: yesEuropean Journal of Histochemistry, 2014
Dopamine D1 and D2 receptor immunohistochemistry and Golgi techniques were used to study the structure of the adult rat arcuate-median eminence complex, and determine the distribution of the dopamine D1 and D2 receptor immunoreactivities therein ...

The passive avoidance task ameliorate the toxic effects of bisphenol A on dopamine D1 receptor density in hippocampus, amygdala, and cerebellum of male rats

open access: yesBrain and Behavior, 2023
Introduction Dopamine D1 receptor seems to play a role in mediating plasticity. Therefore, the present study aimed to investigate the effects of passive avoidance tasks postexposed to BPA on dopamine D1 receptor density in the hippocampus, amygdala, and ...

Pharmacological Evidence That Dopamine Inhibits the Cardioaccelerator Sympathetic Outflow via D2-Like Receptors in Pithed Rats

open access: yesJournal of Pharmacological Sciences, 2013
It has been suggested that N,N-di-n-propyl-dopamine (dopamine analogue) decreased heart rate in rats through stimulation of dopamine receptors. Nevertheless, the role of prejunctional dopamine D1/2-like receptors or even α2-adrenoceptors to mediate ...

A Novel Dopamine Receptor Signaling Unit in Brain: Heterooligomers of D1 And D2 Dopamine Receptors

open access: yesThe Scientific World Journal, 2007
The ability of G protein coupled receptors to heterooligomerize and create novel signaling complexes has demonstrated the tremendous potential of these receptors to access diverse signaling cascades, as well as to modulate the nature of the transduced ...
