A cross-disorder genome-wide association study (GWAS) identified 23 highly pleiotropic single-nucleotide polymorphisms (SNPs) that were associated with at least four neuropsychiatric disorders, and 22 SNPs that were associated predominantly with schizophrenia. Exploring their link to brain-related traits might advance understanding their distinct neurobiological processes. Using the UK Biobank data (n = 28,952), this study examined the association of both a genetic risk score (GRS) for highly pleiotropic SNPs (PleioPsych-GRS), and a GRS for predominantly schizophrenia-associated SNPs (SCZ-GRS) with 154 measures of subcortical volume, cortical thickness, and surface area as well as 12 outcomes related to mental health. To generate further insights at the individual SNP level, the association between SNPs and brain structure was examined using GWAS summary statistics. The PleioPsych-GRS showed no significant association with brain structure after correction for multiple testing. The SCZ-GRS showed a significant association with an increased surface area of the lateral orbitofrontal region, and an increased volume of the putamen, among others. The PleioPsych-GRS and the SCZ-GRS were associated with eight and four outcomes related to mental health, respectively. Two highly pleiotropic and 10 SCZ-associated SNPs were associated with several structural brain phenotypes. Taken together, these findings indicated that GRSs of highly pleiotropic SNPs and predominantly schizophrenia-associated SNPs have partly distinct associations with brain structure and outcomes related to mental health. Thus, investigating schizophrenia-specific and pleiotropic variants may improve our understanding of the neurobiology of neuropsychiatric disorders.</p>","PeriodicalId":23278,"journal":{"name":"Translational Psychiatry","volume":"15 1","pages":"230"},"PeriodicalIF":5.8,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12228695/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144567924","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}

We also conducted co-occurrence network analysis to explore the relationships among differential microbial species and metabolic pathways separately.

Network analysis further uncovered more complex inter-kingdom interactions in SZ patients, with specific fungal species appearing exclusively in the SZ network. Importantly, significant associations were observed between microbial species and functional pathways with clinical characteristics, including symptom severity, cognitive function, and clinical biochemical marker. For instance, the abundance of Streptococcus vestibularis was positively correlated with homocysteine levels; the ubiquinone and other terpenoid-quinone biosynthesis was positively correlated with both symptom severity and C-reactive protein.

Risk for early alcohol use was distributed across multiple domains highlighting the unique information provided by genetic, trait, and environmental variables. Results also indicated the importance of both environmental and genetic factors on time to first sip of alcohol, but that time to first full drink and the progression from sip to drink was most associated with genetic and trait factors rather than broad environmental influences.

Approach-avoidance conflict (AAC) offers a potential framework for identifying treatment outcome predictors and informing optimization of GAD treatment. The current study examined whether pre-treatment neurobehavioral AAC indices predict symptom improvement in behavioral activation (BA) and exposure therapy (EXP) for GAD. Treatment-seeking adults meeting criteria for GAD completed a randomized clinical trial with pre-treatment blinding, conducted from 2016-2021. Participants were randomized to complete 10 manualized sessions of BA or EXP. Participants completed an AAC task during functional magnetic resonance imaging pre-treatment. Computational parameters of task behavior were derived, and neural activity was assessed during decision-making and positive and negative outcomes of decisions. Outcome measures were GAD symptoms and depressive symptoms. Of 121 participants recruited, 56 (29 BA, 27 EXP; mean age 33.0 years; 12.5% male) treatment completers were included in analyses. Greater AAC task avoidance (d = -0.28) and greater left dorsolateral prefrontal cortex activation during negative outcomes (d = -0.32), predicted greater symptom reduction across treatments. Blunted left amygdala activation to positive outcomes was associated at a trend level with favorable symptom reduction for BA but not EXP (d = -0.20). The dorsolateral prefrontal cortex may be a target for enhancing behavior therapy outcomes generally, while left amygdala activation to positive affect may be a target for enhancing outcomes for BA. These findings may inform the optimization of behavioral therapies for GAD and hold potential for transdiagnostic applications, warranting larger, longitudinal studies in clinical settings.

We have recently reported that the vesicular protein Neurensin-2 mediates depression and that its deletion confers profound resilience to chronic stress. Nonetheless, the behavioral and molecular adaptations that underlie the stress resilience in Neurensin-2 knockout mice are still unknown. In this study, we aimed to comprehensively characterize the basal behavioral effects of Neurensin-2 deletion in mice. We used Neurensin-2 knockout male and female mice to examine how Neurensin-2 deletion affects cognitive, emotional, and motor performance in mice. In addition, we examined the impact of Neurensin-2 deletion on body weight, analyzed the stress-induced molecular changes, and tested how these changes affect the excitatory/inhibitory balance. We found that while Neurensin-2 deletion confers basal anxiolysis and weight reduction, no discernible cognitive, social, or motor impairments were detected. Furthermore, we found that Neurensin-2 knockout mice have impaired hippocampal inhibitory transmission, which is resilient to the stress-evoked excitatory/inhibitory imbalance seen in wild-type mice. Our findings suggest that Neurensin-2 deletion confers basal anxiolysis, and shifts the hippocampal excitatory/inhibitory balance. These effects are not accompanied by impaired cognitive function or weight gain.

The BACS was administered to 1807 psychosis patients from the B-SNIP1 and 2 cohorts to perform LPA and identify cognitive subgroups. Regional homogeneity (ReHo), a measure of local functional connectivity, was computed from resting-state fMRI data in a subset (717 patients, 427 controls). Multivariate regression models examined associations between ReHo and cognitive LPA, Biotypes, and DSM diagnostic categories. LPA identified four cognitive profiles: cognitively comparable to controls (CCC), intermediate-1, intermediate-2, and severely impaired. These profiles showed unique dysconnectivity patterns, particularly within the striatal, default mode, salience, and executive control networks. The severely impaired group exhibited hyperconnectivity in basal ganglia and executive control networks. The intermediate groups showed default mode and salience network connectivity disruptions. The CCC group was the least impaired, with hyperconnectivity in sensory and auditory networks. Compared to Biotypes, LPA subgroups presented more domain-specific connectivity fingerprints. Psychosis patients exhibit heterogeneous cognitive profiles with divergent intrinsic functional dysconnectivity patterns.
