Inclusion of Enclosed Hydration Effects in the Binding Free Energy Estimation of Dopamine D3 Receptor Complexes [PDF]

open access: yes, 2019
Confined hydration and conformational flexibility are some of the challenges encountered for the rational design of selective antagonists of G-protein coupled receptors. We present a set of C3-substituted (-)-stepholidine derivatives as potent binders of the dopamine D3 receptor.

Nicotinic and opioid receptor regulation of striatal dopamine D2-receptor mediated transmission

open access: yesScientific Reports, 2016
In addition to dopamine neuron firing, cholinergic interneurons (ChIs) regulate dopamine release in the striatum via presynaptic nicotinic receptors (nAChRs) on dopamine axon terminals.

Association between Parkinson's disease and risk of colorectal cancer: A systematic review and meta‐analysis

open access: yesIbrain, EarlyView.
The aim of this study is to examine the association between Parkinson's disease (PD) and colorectal cancer (CRC) risk through a systematic review and meta‐analysis. This study represents the largest meta‐analysis conducted to date on the relationship between CRC risk and PD.

Modulatory Effects of Dopamine D2 Receptors on Spreading Depression in Rat Somatosensory Neocortex

open access: yesBasic and Clinical Neuroscience, 2014
Introduction: Spreading depression (SD) is a propagating wave of depolarization followed by depression of the neuroglial activities and can modulate extracellular dopamine concentrations in the neocortex.

A biophysical network model reveals the link between deficient inhibitory cognitive control and major neurotransmitter and neural connectivity hypotheses in schizophrenia [PDF]

open access: yesarXiv, 2021
We address a biophysical network dynamical model to study how the modulation of dopamine (DA) activity and related N-methyl-d-aspartate (NMDA) glutamate receptor activity as well as the emerging Pre-Frontal Cortex (PFC) functional connectivity network (FCN) affect inhibitory cognitive function in schizophrenia in an antisaccade task.

Advanced Research on Dopamine Signaling to Develop Drugs for the Treatment of Mental Disorders: Proteins Interacting With the Third Cytoplasmic Loop of Dopamine D2 and D3 Receptors

open access: yesJournal of Pharmacological Sciences, 2010
Among the various dopamine receptors, D2-like receptors (D2R, D3R, and D4R) are characterized by a large third cytoplasmic loop, a short carboxyl-terminal tail, and the ability to activate inhibitory G proteins.

High level modeling of tonic dopamine mechanisms in striatal neurons [PDF]

open access: yesarXiv, 2007
The extant versions of many basal ganglia models use a `gating' model of dopamine function which enhances input to D1 receptor units and attenuates input to D2 receptor units. There is evidence that this model is unsatisfactory because (a) there are not sufficient dopaminergic synapses to gate all input and (b) dopamine's main effect is likely to be on

The influence of microbiome‐derived amino acids metabolites in shaping the glioma immunosuppressive microenvironment

open access: yesInterdisciplinary Medicine, EarlyView.
Left: The disruption of the balance between carcinogenic bacteria and probiotics mediated by antibiotics, protein, and glucose intake. Middle: The gut microbiota‐derived amino acids, primarily through tryptophan, tyrosine, arginine, and branched‐chain amino acid pathways, regulate glioma development via mechanisms such as AHR activation, metabolic ...

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.

Characterisation of AmphiAmR11, an amphioxus (Branchiostoma floridae) D2-dopamine-like G protein-coupled receptor. [PDF]

open access: yesPLoS ONE, 2013
The evolution of the biogenic amine signalling system in vertebrates is unclear. However, insights can be obtained from studying the structures and signalling properties of biogenic amine receptors from the protochordate, amphioxus, which is an ...
