Objective: Caryophyllus aromaticus mill L (Caryophyllus aromaticus) is a herbal spice plant that has several therapeutic effects. It also heals depression, grief, nervous stress and tension. In the present study we evaluated antidepressant-like effect of Caryophyllus aromaticus using forced swimming test (FST). Material and Methods: Three doses of ethanolic extract (50, 100 and 200 mg/kg) was i...
Objective: Rosa damascena mill L (R. damascena) is an ornamental plant that has several therapeutic (such as sedative and hypnotic) effects. It also heals depression, grief, nervous stress and tension. In the present study we evaluated antidepressant-like effect of R. damascena using forced swimming test (FST). Material and Methods: Three doses of aqueous extract (15, 60 and 90 mg/kg) was injec...
Data acquired to date show that some sigma receptor ligands reveal "antidepressant-like" activity in the forced swim test in mice and rats. Moreover, our preliminary results suggested that joint administration of sigma receptor ligands and amantadine (AMA, a glutamatergic/NMDA receptor antagonist) caused a positive interaction in the Porsolt test in rats, as had already been observed in the cas...
Telomere and telomerase alterations have been reported in mood disorders. However, the role of telomerase in depression remains unclear. Here we show that chronic mild stress (CMS) led to a significant decrease in telomerase reverse transcriptase (TERT) level and telomerase activity in the hippocampus. Treatment with antidepressant fluoxetine reversed the CMS-induced TERT and telomerase activit...
Major depressive disorder is among the most commonly diagnosed disabling mental diseases. Several non-pharmacological treatments of depression upregulate adenosine concentration and/or adenosine A1 receptors (A1R) in the brain. To test whether enhanced A1R signaling mediates antidepressant effects, we generated a transgenic mouse with enhanced doxycycline-regulated A1R expression, specifically ...
The primary action of several antidepressant treatments used in the clinic raises extracellular concentrations of serotonin (5-HT), which subsequently act on multiple 5-HT receptors. The present study examined whether 5-HT6 receptors might be involved in the antidepressant-like effects mediated by enhanced neurotransmission at 5-HT synapses. A selective 5-HT6 receptor antagonist, SB271046, was ...
It is known that tianeptine exhibits antidepressant-like activity. Its influence on the glutamatergic system is also known, but the mechanisms involved in this activity remain to be established. The aim of this study was to investigate the involvement of the glutamate pathway in the antidepressant-like action of tianeptine. We investigated the effects of N-methyl-D-aspartate (NMDA) and α-amino-...
Leptin, a hormone secreted from adipose tissue, was originally discovered to regulate body weight. The localization of the leptin receptor in limbic structures suggests a potential role for leptin in emotional processes. Here, we show that rats exposed to chronic unpredictable stress and chronic social defeat exhibit low leptin levels in plasma. Systemic leptin treatment reversed the hedonic-li...
Inflammatory responses induced by peripheral administration of lipopolysaccharide (LPS) triggers depressive-like behavioral syndrome in rodents. Inhibition of phosphodiesterase 4 (PDE4) produces a robust anti-inflammatory effect in inflammatory cells. Unfortunately, archetypal PDE4 inhibitors cause intolerable gastrointestinal side-effects, such as vomiting and nausea. N-isopropyl-3-(cyclopropy...
