Background Obsessive–compulsive disorder (OCD) is a prevalent and severe clinical condition. Robust evidence suggests a gene-environment interplay in its etiopathogenesis, yet the underlying molecular clues remain only partially understood. In order to further deepen our understanding of OCD, it is essential to ascertain how genes interact with env...

Individual differences in temporal and probabilistic discounting are associated with a wide range of life outcomes in literature. Traditional approaches have focused on impulsiveness and cognitive control skills, on goal-oriented personality traits as well as on the psychological perception of time. More recently, literature started to consider the...
Article
Background Brain-Derived Neurotrophic Factor (BDNF) is a promising candidate biomarker in both the development and aetiology of different neuropsychiatric conditions, including obsessive-compulsive disorder (OCD). Most of the studies in the field have been carried out in blood cells, including peripheral blood mononucleated cells (PBMCs), although...
Article
Introduction Several evidence recognizes Brain Derived Neurotrophic Factor (BDNF) as a promising biomarker in the pathophysiology of psychiatric disorders, including Obsessive-Compulsive Disorder (OCD), considering the involvement of epigenetic regulation in BDNF altered expression. Objectives This study aims to investigate, in a sample of OCD pat...
Article
Stress vulnerability is a critical factor for the development of trauma‐related disorders, however its biological underpinnings are not clear. We demonstrated that dysfunctions in the X‐linked epigenetic factor methyl‐CpG binding protein 2 (MeCP2) provide trauma vulnerability in male mice. Given the prominent role of sex in stress outcomes, we expl...

Rationale Serotonin (5-HT) plays an important role in the organization of the central nervous system and in the development of social interaction deficits and psychiatric disorders, including anxiety, depression, and addiction disorders. Notably, disruption of the 5-HT system during sensitive periods of development exerts long-term consequences, in...
Article
Obsessive-Compulsive Disorder (OCD) is a prevalent and severe clinical condition whose hallmarks are excessive, unwanted thoughts (obsessions) and repetitive behaviors (compulsions). The onset of symptoms generally occurs during pre-adult life and typically affects subjects in different aspects of their life's, compromising social and professional...

Background Discriminating between adolescents who will eventually have ethanol use problems from those who do not is important. Environmental enrichment is a promising approach to reduce drug-related problems, but its impact on ethanol’s effects and intake is being scrutinized. Objective: We tested the effects of environmental enrichment on ethanol...
Article
Background DNA methylation plays a relevant role in the regulation of gene transcription, but currently the exact quantification of transcription factors binding to methylated DNA is not being determined. The binding of the transcription factor cAMP response element-binding protein-1 to its cognate CpG containing motif is known to be impaired upon...
Article
Historically, the roots of alcoholism have been linked to either environment or heredity. However, the interaction between these factors is still largely unexplored. The evidence supports a link between alcohol consumption and the endogenous opioid system. We here studied the opioid genes expression in male and female Wistar rats derived from a sho...
Conference Paper
Full-text available
Background: Social Anxiety Disorder (SAD) is a relatively frequent psychiatric disorder, with a lifetime prevalence of about 4% [1], which usually starts in adolescence [2]. As in the case of other mental disorders, [3] SAD has also been linked to academic impairment and school drop-out [4,5], but this previous research has a number of methodologic...
Article
Ethanol use is widespread in adolescents, yet only some transition to problematic drinking. It is important to understand why the risk for problematic drinking varies across sub-groups of adolescents. This study reports a short-term selection program to generate Wistar rat lines (high and low adolescent ethanol drinking, ADHI and ADLO lines, respec...
Article
Background: The brain-derived neurotrophic factor (BDNF) rs6265 (Val66Met) Met allele is associated with early onset (≤ 19 years old) bipolar disorder (BD). Val66Met (G196A) creates a CpG site when the Val/G allele is present. We sought to study the methylation of the BDNF promoter and its interaction with Val66Met genotype in BD. Methods: Sex/a...
Article
Patients suffering from autoimmune diseases are more susceptible to mental disorders yet, the existence of specific cellular and molecular mechanisms behind the co-morbidity of these pathologies is far from being fully elucidated. By generating transgenic mice overexpressing Annexin-A1 exclusively in T cells to study its impact in models of autoimm...
Article
Full-text available
Flavonoids have been shown to modulate GLP-1 in obesity. GLP-1 induces some of its effects through the intestinal GLP-1 receptor (GLP-1R), though no data exist on how flavonoids affect this receptor. Here, we examine how a dose of grape seed proanthocyanidin extract (GSPE) with anti-obesity activity affects intestinal GLP-1R and analyze whether epi...

Full-text available
Prenatal ethanol exposure (PEE) promotes ethanol consumption in the adolescent offspring accompanied by the transcriptional regulation of kappa opioid receptor (KOR) system genes. This study analysed if environmental enrichment (EE, from gestational day 20 to postnatal day 26) exerts protective effects upon PEE-modulation of gene expression, ethano...

Article
Obsessive-compulsive disorder (OCD) is a clinically heterogeneous neuropsychiatric condition associated with profound disability, whose susceptibility, stemming from genetic and environmental factors that intersect with each other, is still under investigation. In this perspective, we sought to explore the transcriptional regulation of Brain Derive...
Article
Objective Binge‐eating episodes are recurrent and are defining features of several eating disorders. Thus binge‐eating episodes might influence eating disorder development of which exact underlying mechanisms are still largely unknown. Methods Here we focused on the transcriptional regulation of the endocannabinoid system, a potent regulator of fe...

Animal models have suggested that prenatal ethanol exposure (PEE) alters the κ opioid receptor system. The present study investigated the brain expression of dynorphin and nociceptin/orphanin FQ related genes and assessed anxiety-like behavior in the light-dark box (LDB), shelter-seeking and risk-taking behaviors in the concentric square field (CSF...
