The traditional acupuncture treatment has been practiced to be effective for the therapy of PSD, but its mechanism still needs to be elucidated. With a combination of methods, including behavioral testing, immunofluorescence, in vivo electrophysiological recording, mRNA sequencing, genetic modulation, and in vivo fiber recording techniques, this study showed that electroacupuncture (EA) at Baihui (GV20) and Shenting (GV24) acupoints improved the depressive-like behaviors and neuronal electrophysiological activities in PSD model mice, which was established by bilateral injection of collagenase IV into the medial prefrontal cortex (mPFC). Moreover, it was found that the EA-mediated improvement was comparable to that of fluoxetine. The mRNA sequence analysis indicated that the 5-hydroxytryptamine (5-HT) system was involved in the pathogenesis of PSD. Meanwhile, the number of 5-HT positive neurons in the dorsal raphe nucleus (DRN) and 5-HT in the mPFC was significantly decreased, and ablation of neurons in the DRN could prevent the efficacy of EA. The neuronal activity of excitatory and inhibitory neurons in mPFC can be modulated by chemogenetic activation or inhibition of the TPH2-positive neurons in the DRN projecting to the mPFC. Together, our results have provided the insight of the biological mechanism underlying acupuncture in the treatment of PSD and revealed the scientific connotation of acupuncture in both clinical and scientific value.</p>","PeriodicalId":23278,"journal":{"name":"Translational Psychiatry","volume":"15 1","pages":"382"},"PeriodicalIF":6.2,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12501360/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145239929","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 first explored the cross-sectional and longitudinal relationships between MetS and suicide attempt, while also exploring the mediating role of cognitive performance. Second, using summary data from the largest genome-wide association studies, the genetic associations between MetS, suicide attempt, and cognitive performance were examined. Of 380,557 participants tracked over 13 years, we identified 1847 new cases of suicide attempt. The presence of MetS was found to significantly increase the risk of suicide attempt (HR = 1.250, 95% CI = 1.134-1.379). In participants lacking traditional suicide risk factors, such as being female, younger, and having higher educational attainment, MetS still presented a greater risk in predicting future suicide attempts. Additionally, MetS and suicide attempt exhibited significant genetic correlation (rg = 0.080 ± 0.026), and Mendelian randomization analysis suggested MetS had a significant negative effect on suicide attempt (β = 0.156, 95% CI = 0.077-0.235).

However, the specific pathogenesis of depression remains to be elucidated. Numerous studies have shown that metabolic disorders and molecules play important roles in MDD. Here, we demonstrate a preliminary mechanism through which TGR5 functions in the hippocampus during bile acid synthesis dysfunction in mice subjected to chronic social defeat stress (CSDS). According to the enzyme-linked immunosorbent assay (ELISA), susceptible mice subjected to CSDS presented reduced expression of key bile acid enzymes in the serum and total bile acids (TBAs) in the hippocampus. The expression of the bile acid-related receptor TGR5 in the hippocampus was lower in CSDS-exposed susceptible mice than in control mice. By analyzing the potential downstream signaling pathways of TGR5, we found that specific TGR5/cAMP/PKA regulation effectively increased the plasticity of Schaffer collateral (SC)-CA1 synapses in the hippocampus and further alleviated anxiety- and depression-like behavior in susceptible mice. These findings suggest that CSDS susceptibility is accompanied by dysfunction of TGR5 in the hippocampus and the downstream cAMP/PKA signaling pathway. Activating cAMP/PKA signaling can ameliorate behavioral deficits in susceptible mice.

In six experiments, we first revealed that lesions targeting the dorsomedial striatum (DMS) significantly impacted performance in a mouse version of the two-choice probabilistic decision-making task, surpassing effects observed in other striatal subregions. Behavioral assessments in HET mice unveiled notable disturbances, including reduced accumulated trials to reach criteria, diminished ratio of lose-stay behavior, elevated learning rates, and decreased choice consistency in reinforcement learning models. Moreover, we found a strong correlation between DMS local field potential power and choice outcome, particularly evident in no-reward condition. The behavioral abnormalities observed in HET mice were restored when the DMS was chemogenetically inhibited, while their locomotor activity remained unaffected. Furthermore, RNA-seq analysis and immunohistochemistry uncovered a decrease in the number of striatal parvalbumin (PV) interneurons in HET mice. Targeted lesioning of PV interneurons in the DMS of wild-type mice resulted in behavioral alterations mirroring those in HET mice. In summary, our findings suggest that Akt1 deficiency-induced downregulation of PV expression alters neural oscillations in the DMS, influencing choice strategies, especially in no-reward condition during probabilistic decision-making.

Here, we constructed a comprehensive disease-specific sQTL map to provide genetic variants that could alter gene activity through RNA splicing in SCZ.

Additional differential splicing analysis of these genes in 539 cases and 754 controls revealed 12 significant genes that may increase SCZ risk due to their AS dysregulation. Notably, five genes (DPYD, LACC1, CCDC122, ANAPC7, and DGKZ) showed consistent splicing regulation effects in both MR analysis and differential splicing analysis. Pathway enrichment analysis of differentially spliced genes revealed potential biologically pathways relevant to SCZ, particularly in synaptic transmission and microtubule movement. Furthermore, single-cell RNA-seq analysis revealed that several genes were preferentially expressed in specific brain cell types, including oligodendrocytes, microglia, and excitatory neurons.

Given the limited understanding of the effects of CBD during pregnancy, we adopted a longitudinal approach to investigate the neurodevelopmental trajectory associated with prenatal CBD exposure. Pregnant mice were administered 3 mg/kg CBD from gestational days 5 to 18. At early adolescence, offspring displayed sex-specific behavioral changes. Females, but not males, exhibited a complex anxiety-like phenotype during the elevated plus maze task. This phenotype persisted into adulthood in the open field test and was accompanied by altered reward responsiveness. Throughout post-natal life, female offspring demonstrated heightened stretch-attend postures, a risk-assessment behavior reflecting approach-avoidance tendencies and anxiety-like behavior. Finally, prenatal CBD exposure increased repetitive behaviors in adult animals of both sexes, as evidenced by the marble burying task. These results provide strong evidence of sex-specific disruptions in the developmental trajectories of anxiety-like behaviors associated with prenatal CBD exposure. They challenge the perception that CBD is universally safe and highlight vulnerabilities linked to gestational CBD exposure.</p>","PeriodicalId":23278,"journal":{"name":"Translational Psychiatry","volume":"15 1","pages":"354"},"PeriodicalIF":6.2,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12500939/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145239915","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}
