Crosstalk Between Kappa Opioid and Dopamine Systems in Compulsive Behaviors

open access: yesFrontiers in Pharmacology, 2020
The strength of goal-oriented behaviors is regulated by midbrain dopamine neurons. Dysfunctions of dopaminergic circuits are observed in drug addiction and obsessive-compulsive disorder.

Down-regulation of serotonergic genes expression in the raphe nuclei of midbrain under chronic social defeat stress in male mice [PDF]

open access: yes, 2011
Background: There is ample experimental evidence supporting the hypothesis that the brain serotonergic system is involved in the control of chronic social defeat stress (CSDS), depression and anxiety.

M3 muscarinic acetylcholine receptor facilitates the endocytosis of mu opioid receptor mediated by morphine independently of the formation of heteromeric complexes [PDF]

open access: yes, 2017
Morphine inefficiency to induce the internalization of mu opioid (MOP) receptors observed in numerous experimental models constitutes a paradigm of G-protein coupled receptor (GPCR) functional selectivity.

Seeking (and Finding) Biased Ligands of the Kappa Opioid Receptor [PDF]

open access: yesACS Medicinal Chemistry Letters, 2017
The discovery and characterization of two classes of kappa opioid receptor agonists that are biased for G protein over βarrestin signaling are described.

Novel approaches for drug development against chronic primary pain: A systematic review

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Cortical kappa opioid receptors integrate negative affect and sleep disturbance

open access: yesTranslational Psychiatry
Sleep disruption and negative affect are attendant features of many psychiatric and neurological conditions that are often co-morbid including major depressive disorder, generalized anxiety disorder and chronic pain.

Xylazine is an agonist at kappa opioid receptors and exhibits sex-specific responses to opioid antagonism

open access: yesAddiction Neuroscience
Xylazine is in the unregulated drug supply at increasing rates, usually combined with fentanyl, necessitating understanding of its pharmacology. Despite commentary from politicians, and public health officials, it is unknown how xylazine impacts naloxone

Stress-Induced Reinstatement of Drug Seeking: 20 Years of Progress [PDF]

open access: yes, 2015
In human addicts, drug relapse and craving are often provoked by stress. Since 1995, this clinical scenario has been studied using a rat model of stress-induced reinstatement of drug seeking.

Systematic Review and Meta‐Analysis of Mortality in Patients With Anorexia Nervosa

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) has one of the highest mortality rates among psychiatric disorders. This systematic review and meta‐analysis examined the all‐cause mortality of AN patients compared to the general population using the standardized mortality ratio (SMR).

Stimulation of peripheral Kappa opioid receptors inhibits inflammatory hyperalgesia via activation of the PI3Kγ/AKT/nNOS/NO signaling pathway

open access: yesMolecular Pain, 2012
BackgroundIn addition to their central effects, opioids cause peripheral analgesia. There is evidence showing that peripheral activation of kappa opioid receptors (KORs) inhibits inflammatory pain.
