Molecular dynamics of dopamine at the D2 receptor. [PDF]
A three-dimensional model of the dopamine D2 receptor, assumed to be a target of antipsychotic drug action, was constructed from its amino acid sequence. The model was based on structural similarities within the super-family of guanine nucleotide-binding regulatory (G) protein-coupled neuroreceptors and has seven alpha-helical transmembrane segments ...

Cocaine Effects on Dopaminergic Transmission Depend on a Balance between Sigma-1 and Sigma-2 Receptor Expression. [PDF]
gma σ1 and σ2 receptors are targets of cocaine. Despite sharing a similar name, the two receptors are structurally unrelated and their physiological role is unknown. Cocaine increases the level of dopamine, a key neurotransmitter in CNS motor control and

5-HT2A Receptors Modulate Dopamine D2-mediated Maternal Effects [PDF]
Serotonin 5-HT2A receptors are expressed throughout the mesolimbic and mesocortical dopamine pathways, and manipulation of this receptor system has a profound impact on dopamine functions and dopamine-mediated behaviors.

Dopamine elevates and lowers astroglial Ca(2+) through distinct pathways depending on local synaptic circuitry [PDF]
Whilst astrocytes in culture invariably respond to dopamine with cytosolic Ca(2+) rises, the dopamine sensitivity of astroglia in situ and its physiological roles remain unknown. To minimize effects of experimental manipulations on astroglial physiology,

Distinct regulation of dopamine D2S and D2L autoreceptor signaling by calcium [PDF]
D2 autoreceptors regulate dopamine release throughout the brain. Two isoforms of the D2 receptor, D2S and D2L, are expressed in midbrain dopamine neurons. Differential roles of these isoforms as autoreceptors are poorly understood.

Dopamine is widely distributed in metazoans and is implicated in many physiological functions. Dopaminergic signaling is mediated through two classes of dopamine receptors, D1-like and D2-like.

Background: Food addiction is a debated topic in neuroscience. Evidence suggests diabetes is related to reduced basal dopamine levels in the nucleus accumbens, similar to persons with drug addiction.

Mechanisms underlying the endogenous dopaminergic inhibition of spinal locomotor circuit function in Xenopus tadpoles [PDF]
This work was supported by the Biotechnology and Biological Science Research Council (BBSRC) [grant number BB/J01446X/1].Dopamine plays important roles in the development and modulation of motor control circuits.

Fluorescent ligands for dopamine D2/D3 receptors [PDF]
AbstractFluorescent ligands are versatile tools for the study of G protein-coupled receptors. Depending on the fluorophore, they can be used for a range of different applications, including fluorescence microscopy and bioluminescence or fluorescence resonance energy transfer (BRET or FRET) assays.

Nicotinic and opioid receptor regulation of striatal dopamine D2-receptor mediated transmission
In addition to dopamine neuron firing, cholinergic interneurons (ChIs) regulate dopamine release in the striatum via presynaptic nicotinic receptors (nAChRs) on dopamine axon terminals.
