Depression is the disease of the modern era. The lack of response to the available antidepressants, which were developed on the basis of the monoaminergic deficit hypothesis of depression, has encouraged scientists to think about new mechanisms explaining the pathogenesis of depression. In this context, the inflammatory theory has emerged to clarify many aspects of depression that the previous theories have failed to explain. Toll-like receptor-4 (TLR-4) has a regulatory role in the brain's immune response to stress, and its activation is suggested to play a pivotal role in the pathophysiology of depression...

Perinatal depression is associated with serious risks for the mother, baby, and family. When considering treating perinatal depression with a drug indicated for the treatment of depression, the major concerns are whether the drug increases the risks of teratogenicity, pregnancy complications, poor neonatal adaptation, or neurodevelopmental disorders. Although different studies have produced different results, the majority have not shown increases in risk for selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, tricyclic antidepressants, or the noradrenergic/dopaminergic drug bupropion...

BACKGROUND: Functional neuroimaging studies have examined the neural substrates of treatments for major depressive disorder (MDD). Low sample size and methodological heterogeneity, however, undermine the generalizability of findings from individual studies. We conducted a meta-analysis to identify reliable neural changes resulting from different modes of treatment for MDD and compared them with each other and with reliable neural functional abnormalities observed in depressed versus control samples...

BACKGROUND: Identifying gene regulatory networks is an important task for understanding biological systems. Time-course measurement data became a valuable resource for inferring gene regulatory networks. Various methods have been presented for reconstructing the networks from time-course measurement data. However, existing methods have been validated on only a limited number of benchmark datasets, and rarely verified on real biological systems. RESULTS: We first integrated benchmark time-course gene expression datasets from previous studies and reassessed the baseline methods...

Studies reported a strong genetic correlation between the Big Five personality traits and major depressive disorder (MDD). Moreover, personality traits are thought to be associated with response to antidepressants treatment that might partly be mediated by genetic factors. In this study, we examined whether polygenic scores (PGSs) derived from the Big Five personality traits predict treatment response and remission in patients with MDD who were prescribed selective serotonin reuptake inhibitors (SSRIs). In addition, we performed meta-analyses of genome-wide association studies (GWASs) on these traits to identify genetic variants underpinning the cross-trait polygenic association...

Objective: The aim of this study is to investigate the effects of exercise as an add-on therapy with antidepressant medication and cognitive behavioral group therapy (CBGT) on treatment outcomes in low-active major depressive disorder (MDD) patients. We also explored whether exercise reduces the residual symptoms of depression, notably cognitive impairment and poor sleep quality, and aimed to identify putative biochemical markers related to treatment response. Methods: Sixteen low-active MDD patients were recruited from a mental health day treatment program at a local hospital...

Major depressive disorder (MDD) is associated with cognitive impairments that may contribute to poor functional outcomes. Clinical data suggests that the multimodal antidepressant vortioxetine attenuates some cognitive impairments in MDD patients, but the mechanistic basis for these improvements is unclear. One theory suggests that vortioxetine improves cognition by suppressing γ-amino butyric acid (GABA)ergic neurotransmission, thereby increasing glutamatergic activation. Vortioxetine's effects on cognition, GABA and glutamate neurotransmission have been supported in separate experiments, but no empirical work has directly connected vortioxetine's cognitive effects to those on GABA and glutamate neurotransmission...

In spite of tremendous development in central nervous system research, current treatment is suboptimal, especially in severe mental disorders. In medicine, there are two main methods of improving the health care provided: seeking new treatment procedures and perfecting (optimizing) the existing ones. Optimization of treatment includes not only practical tools such as therapeutic drug monitoring but also implementation of general trends in the clinical practice. New pharmacological options include new more sophisticated forms of monoaminergic drugs, old drugs rediscovered on the base of a better understanding of pathophysiology of mental illnesses, and drugs aimed at new treatment targets...

AIM: Similar to ketamine, xenon gas acts as a glutamatergic N-methyl-d -aspartate receptor antagonist, but devoid of propensity to cause untoward effects. Herein, we loaded xenon gas into a liposomal carrier called xenon-containing liposomes (Xe-liposome) for systemic delivery, and investigated its effect as an antidepressant and also analyzed synaptic biomarkers including brain-derived neurotrophic factor (BDNF), protein kinase B (AKT), mammalian target of rapamycin (mTOR), protein kinase C (PKC) and extracellular signal-regulated kinase-1/2 (ERK1/2) in blood and brain...

BACKGROUND: Depression is a frequent comorbidity in chronic heart failure. It can be triggered by the experience of suffering from heart disease, but it can also play a causal role in accelerated development and poor prognosis of heart failure. OBJECTIVES: The aim of this study was to investigate the interrelationships between heart failure and depression and the psychophysiological and behavioral mechanisms involved in this association. The effects of comorbid depression on quality of life in patients with heart failure were also examined and therapeutic options reviewed...

As an opportunistic fungal pathogen Candida spp. has the ability to form biofilms. The most prescribed drugs for Candida infections, azoles, have shown to be less effective when biofilms are present. In addition, increasing treatment costs and the fact that most prescribed antifungal drugs have only fungistatic activity justify the search for new treatment strategies. One promising approach is third generation antidepressants, selective serotonin re-uptake inhibitors (SSRIs), because of their proven antifungal activity against several Candida spp...

INTRODUCTION: The development and validation of serotonin transporter reuptake inhibition assays in 96-well format using commercially available human placental choriocarcinoma JAR cells is described. METHODS: AR cells were first shown to uptake [3 H]serotonin in a saturable fashion with a KM value of 1 μM as determined by a Michaelis-Menten kinetic analysis. The cells were then utilized to determine the reuptake inhibition potencies of known ligands and the results were compared with results previously generated in the two most commonly used transporter assays (rat brain synaptosomes and transfected HEK293 cells)...

Evidence showed that the stress hormone corticosterone (CORT) injection resulted in dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis implicated in major depressive disorder. Magnolol, main constituent identified in the barks of Magnolia officinalis, exerted antidepressant effects in a rat model of depression induced by chronic unpredictable mild stress in previous studies. However, its antidepressant-like effects and mechanisms have never been studied in depression model induced by CORT administration in rodents...

NLX-112 (a.k.a. F13640 or befiradol) possesses marked activity in a variety of animal models of pain and of neuropsychiatric disorders; it exhibits nanomolar affinity, exceptional selectivity and high agonist efficacy at 5-hydroxytryptamine 1A (5-HT1A ) receptors. Although NLX-112 has been shown to activate 5-HT1A postsynaptic heteroreceptors in the prefrontal cortex (PFC), a brain region involved in the control of depressive states, the influence of NLX-112 on spinal cord 5-HT1A receptors (implicated in the control of pain) has not been described...

Immune system activation and neuroinflammation appear to play a key role in the pathophysiology and treatment of bipolar depression (BDD). This study is the first to analyze blood levels of the pro-inflammatory biomarker C-reactive protein (CRP) in bipolar disorder patients treated with the cyclooxygenase-2 inhibitor, celecoxib (CBX). In this double-blind study, 47 consenting patients with BDD were randomized to receive either escitalopram (10 mg twice/day) + CBX (200 mg twice/day), or escitalopram (10 mg twice/day) + placebo (twice/day)...
