This study investigated changes in local brain activity in BD patients (BDPs) following treatment, evaluated the diagnostic and prognostic potential of regional homogeneity (ReHo), and explored associated genes and biological processes. Resting-state fMRI data and clinical variables were collected from 68 BDPs (at baseline and after 3 months of pharmacotherapy) and 80 healthy controls (HCs). Local brain activity was assessed using Kendall's coefficient of concordance ReHo (KCC-ReHo) and Coherence ReHo (Cohe-ReHo). Support Vector Machine (SVM) and Support Vector Regression (SVR) were employed for classification and treatment response prediction. Neuroimaging-transcriptomic analysis was conducted to explore the relationship between altered ReHo and gene expression profiles from the Allen Human Brain Atlas. BDPs exhibited greater KCC-ReHo and Cohe-ReHo values in the striatum and cerebellum circuit, but lower values in the prefrontal cortex compared to HCs. Following pharmacotherapy, KCC-ReHo values in the cerebellum circuit decreased. Classification accuracy was 68 % (AUC: 0.76 and 0.75 for KCC-ReHo and Cohe-ReHo, respectively), with predicted treatment response moderately correlating with actual outcomes (<em>r</em> = 0.34 and 0.31). Twenty-seven genes were found to be associated with ReHo group differences. Our findings underscore the dysfunction of the prefrontal-striatum and cerebellar circuits as key neuropathological mechanisms in BD.

However, the contribution of the central histaminergic system in the stress induced anxiety, still remains unclear. Therefore, the present study explored the plausible role of central histaminergic transmission in stress-induced anxiety measures in mice using LDB test and in the expression of CORT, CREB, or BDNF levels in the whole brain, PFC, amygdala, and hippocampus of mice. The mice were exposed to the SPS protocol and subsequently left undisturbed for 7 days. On the 8th day, non-SPS/SPS exposed mice were treated i.c.v with histaminergic agents such as histamine, or histamine precursor, l-histidine, H<sub>1</sub> agonist, FMPH, H<sub>2</sub> agonist, amthamine, H<sub>1</sub> antagonist, cetirizine or H<sub>2</sub> antagonist, ranitidine or H<sub>3</sub> inverse agonist, thioperamide and thereafter evaluated for changes in expression of anxiety followed by estimation of CORT, CREB and BDNF levels in brain. Results revealed that SPS-exposed mice elicit heightened anxiety-like behavior accompanied by increased levels of blood or brain histamine and CORT with reduced BDNF/CREB expression in the all-brain tissues. Administration of histaminergic enhancing agents to SPS-exposed mice potentiated the higher expression of anxiety, also further enhanced CORT, and diminished the BDNF/CREB expression in all brain regions. Conversely, central injection of the H<sub>1</sub> receptor antagonist, cetirizine (0.1 μg/mouse) or H<sub>2</sub> receptor antagonist, ranitidine (10 μg/mouse, i.c.v) to SPS mice completely alleviated all the stressed induced changes while H<sub>3</sub> receptor inverse agonist, thioperamide (2, 10 μg/mouse) failed to affect CORT but restored basal anxiety, CREB and BDNF expression. Thus, the blockade of central histamine H<sub>1</sub>/H<sub>2</sub>/H<sub>3</sub> receptors might mitigate SPS-induced anxiety-like manifestations by extenuating the SPS-induced CORT, CREB, and BDNF expression.</div></div>","PeriodicalId":19139,"journal":{"name":"Neuropharmacology","volume":"278 ","pages":"Article 110564"},"PeriodicalIF":4.6,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144476123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout this transition from childhood to adulthood, the adolescent brain is in a critical developmental period. This is especially true for the prefrontal cortex and hippocampus, essential areas for executive functioning. The formation of lasting synaptic connections and dynamic plasticity within the adolescent brain make it especially vulnerable to environmental insults, such as a poor-quality diet. Herein, we review research pertaining to the period of adolescence with respect to food intake control as well as the impact of the modern food environment on the development of the prefrontal cortex and hippocampus and discuss implications for ingestive behaviors throughout rest of life.</div></div>","PeriodicalId":19139,"journal":{"name":"Neuropharmacology","volume":"278 ","pages":"Article 110570"},"PeriodicalIF":4.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144369100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
