Crosstalk Between Kappa Opioid and Dopamine Systems in Compulsive Behaviors
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]
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]
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.

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

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