Role of serotonin via 5-HT2B receptors in the reinforcing effects of MDMA in mice. [PDF]

PLoS ONE, 2009
The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) reverses dopamine and serotonin transporters to produce efflux of dopamine and serotonin, respectively, in regions of the brain that have been implicated in reward. However, the

Striatal dopamine D2/D3 receptor binding in pathological gambling is correlated with mood-related impulsivity [PDF]

, 2012
Pathological gambling (PG) is a behavioural addiction associated with elevated impulsivity and suspected dopamine dysregulation. Reduced striatal dopamine D2/D3 receptor availability has been reported in drug addiction, and may constitute a premorbid ...

Dopamine D4 Receptors

Japanese 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.

D1 Dopamine Receptor Activation Induces Neuronal eEF2 Pathway-Dependent Protein Synthesis

Frontiers in Molecular Neuroscience, 2020
Dopamine, alongside other neuromodulators, defines brain and neuronal states, inter alia through regulation of global and local mRNA translation. Yet, the signaling pathways underlying the effects of dopamine on mRNA translation and psychiatric disorders

Direct Surface Modification of the Epidermis Using Mussel‐Inspired Polydopamine with Multiple Anti‐Biofouling Functions

Advanced Healthcare Materials, EarlyView.
Surface modification using mussel‐derived polydopamine (PDA) is a versatile and robust biocompatible strategy that enables direct application to various epidermal surfaces, regardless of their morphological complexity or surface characteristics. The PDA‐coated epidermis exhibits multiple anti‐biofouling functionalities, including antibacterial and anti‐

Kappa-opioid receptor signaling in the striatum as a potential modulator of dopamine transmission in cocaine dependence

Frontiers in Psychiatry, 2013
Cocaine addiction is accompanied by a decrease in striatal dopamine signaling, measured as a decrease in dopamine D2 receptor binding as well as blunted dopamine release in the striatum. These alterations in dopamine transmission have clinical relevance,

Failure of Intravenous Morphine to Serve as an Effective Instrumental Reinforcer in Dopamine D2 Receptor Knock-Out Mice [PDF]

, 2002
The rewarding effects of opiates are thought to be mediated through dopaminergic mechanisms in the ventral tegmental area, dopamine-independent mechanisms in the nucleus accumbens, or both. The purpose of the present study was to explore the contribution
