Dopamine D1, D2, D3 receptors, vesicular monoamine transporter type-2 (VMAT2) and dopamine transporter (DAT) densities in aged human brain. [PDF]

open access: yesPLoS ONE, 2012
The dopamine D(1), D(2), D(3) receptors, vesicular monoamine transporter type-2 (VMAT2), and dopamine transporter (DAT) densities were measured in 11 aged human brains (aged 77-107.8, mean: 91 years) by quantitative autoradiography.

Dopamine D4 Receptors

open access: yesJapanese Journal of Pharmacology, 2000
Initial investigations on dopamine D4 receptors generated much interest in the role of this receptor in schizophrenia and other aspects of human behavior, as well as new opportunities for novel therapeutics. However, attempts to treat patients suffering from schizophrenia with dopamine D4 agents have failed to yield satisfactory results so far.

In Vitro and In Vivo Characterization of PCC0104005, a Novel Modulator of Serotonin-Dopamine Activity, as an Atypical Antipsychotic Drug

open access: yesScientific Reports, 2018
PCC0104005 is a novel drug candidate for treating schizophrenia that displays high affinity for serotonin, dopamine, and noradrenaline receptors, including partial agonism at dopamine D2, D3, D4, serotonin 5-HT1A, and 5-HT2A receptors and antagonism at 5-

Change of dopamine receptor mRNA expression in lymphocyte of schizophrenic patients

open access: yesBMC Medical Genetics, 2001
Background Though the dysfunction of central dopaminergic system has been proposed, the etiology or pathogenesis of schizophrenia is still uncertain partly due to limited accessibility to dopamine receptor. The purpose of this study was to define whether

M₅ muscarinic receptors mediate striatal dopamine activation by ventral tegmental morphine and pedunculopontine stimulation in mice. [PDF]

open access: yesPLoS ONE, 2011
Opiates, like other addictive drugs, elevate forebrain dopamine levels and are thought to do so mainly by inhibiting GABA neurons near the ventral tegmental area (VTA), in turn leading to a disinhibition of dopamine neurons.

Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]

open access: yes, 2004
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release.

D2-Like Receptors Mediate Dopamine-Inhibited Insulin Secretion via Ion Channels in Rat Pancreatic β-Cells

open access: yesFrontiers in Endocrinology, 2020
Dopamine (DA) has a vital role in the central nervous system and also modulates lipid and glucose metabolism. The present study aimed to investigate the effect of dopamine on insulin secretion and the underlying mechanisms in rat pancreatic β-cells. Data

Purkinje cell dopaminergic inputs to astrocytes regulate cerebellar-dependent behavior

open access: yesNature Communications, 2023
The role of dopamine in the cerebellum remains relatively unexplored. Here, the authors report a dopamine system in the cerebellum in mice, where Purkinje cells supply dopamine and Bergmann glia express D1 receptors.

Orexin-Corticotropin-Releasing Factor Receptor Heteromers in the Ventral Tegmental Area as Targets for Cocaine [PDF]

open access: yes, 2015
Release of the neuropeptides corticotropin-releasing factor (CRF) and orexin-A in the ventral tegmental area (VTA) play an important role in stress-induced cocaine-seeking behavior.

Probing the role of the cation–π interaction in the binding sites of GPCRs using unnatural amino acids [PDF]

open access: yes, 2009
We describe a general application of the nonsense suppression methodology for unnatural amino acid incorporation to probe drug–receptor interactions in functional G protein-coupled receptors (GPCRs), evaluating the binding sites of both the M2 muscarinic
