Cross ‐species studies of cognition relevant to drug discovery: A translational approach
This Review advances the case that bidirectional, cross‐species translation of findings from experimental animals to and from humans is an important strategy for drug discovery. Animal models of mental disorders require appropriate behavioural or cognitive outcome variables that can be generalized cross‐species. One example is the treatment of impulsive behaviour in attention deficit hyperactivity disorder (ADHD) with stimulant drugs. Performance on the stop signal reaction task as an index of impulsivity is improved both in healthy human volunteers and in patients with adult ADHD by stimulant drugs and also by the sel...

Double-blind switch study of vilazodone in the treatment of major depressive disorder
Approximately 40% of patients treated for depression do not respond to a trial of an antidepressant. The aim of the proposed study was to evaluate the efficacy and safety of switching to vilazodone in patients with major depressive disorder who are unresponsive or only partially responsive to a trial of citalopram. Seventy-nine adults with major depressive disorder were enrolled in an open-label study of citalopram (20 mg/day) for 6 weeks. Those still symptomatic after 6-weeks of citalopram were randomly assigned to either a higher dose of citalopram (40 mg/day) or to vilazodone in a double-blind trial for 6 ...

Sigma-1 Receptor Agonists and Their Clinical Implications in Neuropsychiatric Disorders.
Authors: Albayrak Y, Hashimoto K Abstract Accumulating evidence suggests that sigma-1 receptors play a role in the pathophysiology of neuropsychiatric diseases, as well as in the mechanisms of some selective serotonin reuptake inhibitors (SSRIs). Among the SSRIs, the order of affinity for sigma-1 receptors is as follows: fluvoxamine> sertraline> fluoxetine> escitalopram> citalopram>> paroxetine. Some SSRIs (e.g., fluvoxamine, fluoxetine and escitalopram) and other drugs (donepezil , ifenprodil , dehydroepiandeterone (DHEA)) potentiate nerve-growth factor (NGF)-induced neurite outgrowth in PC12 cel...

An update on the advancements in the treatment of agitation in Alzheimer's disease.
Authors: Porsteinsson AP, Antonsdottir IM Abstract INTRODUCTION: Neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) are associated with significant negative outcomes for patients and their caregivers. Agitation, one of the most distressing NPS, lacks well-established long term interventions that are both effective and safe. While nonpharmacological interventions are suggested as first-line treatment, they aren't effective in managing symptoms for every patient, resulting in pharmacological interventions for some patients. Traditionally these interventions consist of off-label use of antipsychotics, sedativ...

Dapoxetine induces neuroprotective effects against glutamate-induced neuronal cell death by inhibiting calcium signaling and mitochondrial depolarization in cultured rat hippocampal neurons.
Abstract Selective serotonin reuptake inhibitors (SSRIs) have an inhibitory effect on various ion channels including Ca(2+) channels. We used fluorescent dye-based digital imaging, whole-cell patch clamping and cytotoxicity assays to examine whether dapoxetine, a novel rapid-acting SSRI, affect glutamate-induced calcium signaling, mitochondrial depolarization and neuronal cell death in cultured rat hippocampal neurons. Pretreatment with dapoxetine for 10min inhibited glutamate-induced intracellular free Ca(2+) concentration ([Ca(2+)]i) increases in a concentration-dependent manner (Half maximal inhibitory concentr...

Further evaluation of mechanisms associated with the antidepressant-like signature of scopolamine in mice.
Abstract Conventional antidepressants lack efficacy for many patients (treatment-resistant depression or TRD) and generally take weeks to produce full therapeutic response in others. Emerging data has identified certain drugs such as ketamine as rapidly-acting antidepressants for major depressive disorder and TRD. Scopolamine, a drug used to treat motion sickness and nausea, has also been demonstrated to function as a rapidly-acting antidepressant. The mechanisms associated with efficacy in TRD patients and rapid onset of action have been suggested to involve a-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (A...

Depressive-like effect of prenatal exposure to DDT involves global DNA hypomethylation and impairment of GPER1/ESR1 protein levels but not ESR2 and AHR/ARNT signaling
This study demonstrated the isomer-specific induction of depressive-like behavior and impairment of Htr1a/serotonin signaling in one-month-old mice that were prenatally exposed to DDT. The effects were reversed by the antidepressant citalopram as evidenced in the forced swimming (FST) and tail suspension (TST) tests in the male and female mice. Prenatally administered DDT accumulated in mouse brain as determined with gas chromatography and tandem mass spectrometry, led to global DNA hypomethylation, and altered the levels of methylated DNA in specific genes.

Beyond negative valence: 2-week administration of a serotonergic antidepressant enhances both reward and effort learning signals
by Jacqueline Scholl, Nils Kolling, Natalie Nelissen, Michael Browning, Matthew F. S. Rushworth, Catherine J. Harmer To make good decisions, humans need to learn about and integrate different sources of appetitive and aversive information. While serotonin has been linked to value-based decision-making, its role in learning is less clear, with acute manipulations often producing inconsistent results. Here, we sho w that when the effects of a selective serotonin reuptake inhibitor (SSRI, citalopram) are studied over longer timescales, learning is robustly improved.

Effects of acute dopaminergic and serotonergic manipulations in the ACI paradigm depend on the basal valence of cognitive judgement bias in rats.
Abstract Recent findings have revealed that pharmacological enhancement of dopaminergic (DA) function by the administration of a DA precursor (dihydroxy-L-phenylalanine; L-DOPA), but not the selective serotonin reuptake inhibitor (SSRI) citalopram, increases an optimism bias in humans. To test whether dopamine might play a similar role in non-human animals, in the present study, we evaluated the effects of acute injections of L-DOPA, the D2 receptor antagonist haloperidol, and the SSRI escitalopram on cognitive judgement bias of rats in the ambiguous-cue interpretation (ACI) paradigm.

Inhibition of the NMDA and AMPA receptor channels by antidepressants and antipsychotics.
In this study we systematically studied action of seven drugs (Fluoxetine, Citalopram, Desipramine, Amitriptyline, Atomoxetine, Chlorpromazine, and Clozapine) on NMDA receptors and Ca(2+)-permeable and -impermeable AMPA receptors in rat brain neurons by whole-cell patch-clamp technique. Except for weak effect of fluoxetine, all drugs were virtually inactive against Ca(2+)-impermeable AMPA receptors. Fluoxetine and desipramine significantly inhibited Ca(2+)-permeable AMPA receptors (IC50 = 43±7 and 105±12 µM, respectively).

Quality of Life and Functioning in Comorbid Posttraumatic Stress Disorder and Major Depressive Disorder After Treatment With Citalopram Monotherapy
Conclusions: Findings suggested that participants with MDD + PTSD are at a greater risk for severe impairment across all domains and less likely to achieve remission from MDD after treatment with citalopram monotherapy. As such, the use of patient-reported measures of QOL and functioning may inform practicing clinicians' and clinical trial researchers' abilities to develop appropriate interventions and monitor treatment efficacy. More importantly, we encourage clinicians and health care providers to routinely screen for PTSD in patients with MDD because this at-risk group requires tailored and specific pharmacotherapy and ...

The injury of serotonin on intestinal epithelium cell renewal of weaned diarrhoea mice
Diarrhoea is a common cause of death in children and weaned animals. Recent research has found that serotonin (5-HT) in the gastrointestinal tract plays an important role in regulating growth and the maintenance of mucosa, which protect against diarrhoea. To determine the influence of 5-HT on intestinal epithelium cell renewal under weaned stress diarrhoea, a weaned-stress diarrhoea mouse model was established with senna infusion (15 mL/Kg)via intragastric administration and stress restraint (SR). Mice with an increase in 5-HT were induced by intraperitoneal injection with citalopram hydrobromide (CH, 10 mg/Kg). The result...
