Dystonia: sparse synapses for D2 receptors in striatum of a DYT1 knock-out mouse model [PDF]

, 2020
Dystonia pathophysiology has been partly linked to downregulation and dysfunction of dopamine D2 receptors in striatum. We aimed to investigate the possible morpho-structural correlates of D2 receptor downregulation in the striatum of a DYT1 Tor1a mouse ...

Buprenorphine is a weak dopamine releaser relative to heroin, but its pretreatment attenuates heroin‐evoked dopamine release in rats

Neuropsychopharmacology Reports, 2020
Aims The United States of America is currently in an opioid epidemic. Heroin remains the most lethal opioid option with its death rate increasing by over 500% in the last decade.

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

Journal 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 ...

Heteroreceptor complexes and their allosteric receptor-receptor interactions in the central nervous system. Focus on examples from Dopamine D2 and Serotonin 5-HT1a receptors [PDF]

, 2018
GPCR interacting proteins (specially β- arrestin) and their receptor-protein interactions are also covered but their interactions with the allosteric receptor-receptor interactions in heteroreceptor complexes remain to be elucidated.

Accelerated Progression of Gait Impairment in Parkinson's Disease and REM Sleep Without Atonia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with Parkinson's disease (PD) and rapid eye movement (REM) sleep without atonia (RSWA) often have more severe gait disturbances compared to PD without RSWA. The association between the presence and expression of RSWA and the rate of progression of gait impairment in PD is unknown.

Voltage-Dependent Dopamine Potency at D1-Like Dopamine Receptors

Frontiers in Pharmacology, 2020
In recent years, transmembrane voltage has been found to modify agonist potencies at several G protein-coupled receptors (GPCRs). Whereas the voltage sensitivities of the Gαi/o-coupled dopamine D2-like receptors (D2R, D3R, D4R) have previously been ...

D₂ Dopamine Receptors Colocalize Regulator of G-Protein Signaling 9-2 (RGS9-2) via the RGS9 DEP Domain, and RGS9 Knock-Out Mice Develop Dyskinesias Associated with Dopamine Pathways [PDF]

, 2005
Regulator of G-protein signaling 9-2 (RGS9-2), a member of the RGS family of Gα GTPase accelerating proteins, is expressed specifically in the striatum, which participates in antipsychotic-induced tardive dyskinesia and in levodopa-induced dyskinesia. We

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.

DOPAMINE AND THE BIOLOGY OF CREATIVITY: LESSONS FROM PARKINSON’S DISEASE

Frontiers in Neurology, 2014
BACKGROUND: Parkinson’s disease (PD) is characterized by reduced flexibility, conceptualization and visuo-spatial abilities. Although these are essential to creativity, case studies show emergence of creativity during PD.
