Dysregulation of dopamine neurotransmission in the nucleus accumbens in immobilization-induced hypersensitivity

open access: yesFrontiers in Pharmacology, 2022
Cast immobilization causes sensory hypersensitivity, which is also a symptom of neuropathic pain and chronic pain. However, the mechanisms underlying immobilization-induced hypersensitivity remain unclear.

Gray-matter volume, midbrain dopamine D2/D3 receptors and drug craving in methamphetamine users. [PDF]

open access: yes, 2015
Dysfunction of the mesocorticolimbic system has a critical role in clinical features of addiction. Despite evidence suggesting that midbrain dopamine receptors influence amphetamine-induced dopamine release and that dopamine is involved in ...

Cortical Dopamine Transmission as Measured with the [11C]FLB 457 - Amphetamine PET Imaging Paradigm Is Not Influenced by COMT Genotype. [PDF]

open access: yesPLoS ONE, 2016
Basic investigations link a Val158Met polymorphism (rs4680) in the catechol-O-methyltransferase (COMT) gene to not only its enzymatic activity, but also to its dopaminergic tone in the prefrontal cortex.

Dopamine agonists in Parkinson’s disease: Impact of D1-like or D2-like dopamine receptor subtype selectivity and avenues for future treatment

open access: yesClinical Parkinsonism & Related Disorders, 2023
Dopamine agonists (DAs) have demonstrated efficacy for the treatment of Parkinson’s disease (PD) but are limited by adverse effects (AEs). DAs can vary considerably in their receptor subtype selectivity and affinity, chemical composition, receptor ...

Abundant immunohistochemical expression of dopamine D2 receptor and p53 protein in meningiomas: follow-up, relation to gender, age, tumor grade, and recurrence [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2015
Meningiomas are common, usually benign tumors, with a high postoperative recurrence rate. However, the genesis and development of these tumors remain controversial.

Antisera specific for D2 dopamine receptors [PDF]

open access: yesBiochemical Journal, 1993
Antisera have been raised against two peptides from the sequence of D2 dopamine receptors: peptide 1 from the predicted second extracellular loop and peptide 2 from the predicted third intracellular loop. The antisera recognize specifically a 95 kDa band in Western blots of several bovine brain regions, which corresponds to the denatured D2 dopamine ...

Voltage sensitivity of dopamine D2-like receptors [PDF]

open access: yes, 2011
G protein coupled receptors (GPCRs) mediate a multitude of responses serving hormonal, neurotransmitter, and sensory functions. These receptors are important drug targets; in fact, about 27 % of prescribed drugs are GPCR ligands.

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

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.

Initial d2 dopamine receptor sensitivity predicts cocaine sensitivity and reward in rats. [PDF]

open access: yesPLoS ONE, 2013
The activation of dopamine receptors within the mesolimbic dopamine system is known to be involved in the initiation and maintenance of cocaine use. Expression of the D2 dopamine receptor subtype has been implicated as both a predisposing factor and ...
