We hypothesised that a maternal high-fat diet (mHFD) would act as a stressor, increasing glucocorticoids, resulting in an altered redox balance and disrupted neuronal plasticity of the limbic system. Such enduring effects would impair the emotional and cognitive profile, neuroendocrine responses, and metabolic and redox homeostasis in the adult offspring. We utilised a mouse model and a translational cellular model employing human neurons derived from inducible Pluripotent Stem Cells (iPSCs) to evaluate the impact of mHFD on neurodevelopment and to test the protection afforded by the antioxidant N-acetyl-cysteine (NAC). Our approach combined behavioural and metabolic phenotyping, biochemical assays, morphological assessment, and targeted gene expression analysis. Results indicate that prenatal administration of NAC prevented anxiety-like and risk-taking behaviours, cognitive impairments and metabolic alterations in mHFD adult mouse offspring, particularly in females. These changes were accompanied by hippocampal downregulation of genes involved in neuronal plasticity, such as BDNF. Using human neurons in vitro, pre-treatment with NAC rescued the negative effects of glucocorticoids on neuronal plasticity via a BDNF-mediated mechanism. The protective effects of NAC over mHFD in females suggest that rebalancing the redox status could be exploited as an overall strategy to buffer the negative effects of early adversities on neurodevelopment.</p>","PeriodicalId":23278,"journal":{"name":"Translational Psychiatry","volume":"15 1","pages":"306"},"PeriodicalIF":6.2,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12373772/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144970513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, we investigated social media-related reward processing in NSSI by recruiting ninety-one young women, divided into three groups: a clinical group (NSSI with borderline personality disorder), a subclinical group (NSSI without co-occurring disorders), and a healthy control group. While undergoing functional magnetic resonance imaging (fMRI), participants received positive and negative comments on their own Instagram photos in a naturalistic task simulating real-life social media interactions. Clinical participants rated positive comments as less pleasant and negative comments as more unpleasant than controls. Coherently, they showed blunted activation in core reward regions such as the nucleus accumbens, caudate, and medial frontal cortex when receiving positive vs negative feedback. Subclinical participants reacted similarly to clinical participants to negative feedback but similarly to controls to positive feedback and presented intermediate activation in most regions, bridging the pattern observed in controls and patients. Results highlight reward system dysfunction as central to NSSI pathology, with both clinical and subclinical groups showing altered processing of social media-based feedback.

The difference between brain structure age (BSA) applied by support vector regression (SVR) and chronological age was calculated to derive the brain structure age gap estimation (BSAGE).

Canonical Correlation Analysis - a multivariate data-reduction technique - revealed two genetic dimensions of mental illness from the polygenic risk scores for ADHD, Anxiety, Depression, and Psychosis. The first dimension represented liability for broad psychopathology which was positively correlated with adversity. The second dimension represented neurodevelopmental-specific risk which negatively interacted with adversity, suggesting that neurodevelopmental symptoms may arise from unique combinations of genetic and environmental factors that differ from other symptom domains. Next, we investigated the cortico-limbic signature of adversity and genetic liability using Partial Least Squares. We found that the neural correlates of adversity broadly mirrored those of genetic liability, with adversity capturing most of the shared variance.
