During typical late-postnatal CNS development, net reductions in dendritic spine densities are associated with activity-dependent learning. Prior results showed agonist exposure in young animals increased spine densities in a subset of song regions while adult exposures did not, suggesting

Cannabinoid inverse agonists possess antidepressant-like properties, but the mechanism of this action is unknown. Numerous studies have reported the interaction between opioid and cannabinoid pathways. In this study, acute foot-shock stress was used in mice to investigate the involvement of the

Depression is one of the frequently-observed psychiatric symptoms associated with nicotine (NC) use. In the present study, considering the unique effects of NC (e.g. antidepressant effects have also been reported), the time course of the NC-induced depressive behavioral alterations in a mouse model

The main clinically used antidepressant drugs are selective monoamine reuptake inhibitors, including selective serotonin reuptake inhibitors (citalopram, sertraline), selective dopamine reuptake inhibitor (nomifensine) and selective noradrenaline reuptake inhibitor (reboxetine), but they have

Similar to clinically used antidepressants, cannabinoids can also regulate anxiety and depressive symptoms. Although the mechanisms of these effects are not completely understood, recent evidence suggests that changes in endocannabinoid system could be involved in some actions of antidepressants.

Increasingly, children and adolescents are being treated for underlying psychopathology commonly associated with the psychoactive substance use disorders. Despite this apparent increase in using medication, little is known about the interaction of drugs of abuse with the psychotropic medications.

OBJECTIVE During the last few decades, endocannabinoid system has emerged as a novel possible target for antidepressant treatment. Although the medical literature provides information on the mood-changing effects of CB1 ligands, little is known about the possible interaction between the simultaneous

The endocannabinoid (eCB) system plays a significant role in the pathophysiology of depression. The potential participation of this system in the mechanism of action of antidepressants has been highlighted in recent years. The aim of this study was to investigate the expression of cannabinoid (CB)

Available data support the notion that cannabinoids, whose therapeutic value is limited due to severe adverse reactions, could be beneficial as adjunctive agents in the management of mood disorders. Polytherapy, which is superior to monotherapy in the terms of effectiveness, usually requires lower

Systemic administration of direct cannabinoid CB1 receptor agonists and inhibitors of the hydrolytic enzyme fatty acid amide hydrolase have been shown to elicit antidepressant effects. Moreover, the endocannabinoid system in the hippocampus is sensitive to both chronic stress and antidepressant

Although a lot of information can be found on the specific dual role of the endocannabinoid system in the emotional-related responses, little is known whether stimulation or inhibition of the CB receptors may affect the activity of the frequently prescribed antidepressant drugs. Our interests have

The goal of this study was to determine whether the endocannabinoid system is altered by chronic antidepressant treatment. The effects of 3-week administration of the monoamine oxidase inhibitor, tranylcypromine (10 mg/kg) and the selective serotonin reuptake inhibitor, fluoxetine (5 mg/kg) on

Several lines of evidence suggest that cannabis may have antidepressant effects. However, methodologic limitations in available studies make the results difficult to interpret. We review this literature and present five cases in which the evidence seems particularly clear that marijuana produced a

Hypothalamic-pituitary-adrenocortical (HPA) axis hyperactivity is associated with major depressive disorders, and treatment with classical antidepressants ameliorates not only psychopathological symptoms, but also the dysregulation of the HPA axis. Here, we further elucidated the role of impaired
