Here, male mice are classified into high-trait anxiety (HTA) and low-trait anxiety (LTA) groups based on their anxiety responses to elevated platform exposure in the open field test. Under observational learning-based vicarious social defeat stress (VSDS), HTA mice exhibit less social avoidance behavior toward CD1 aggressors than LTA mice. Fiber photometry reveals that HTA mice display higher activity of ventral tegmental area (VTA) dopaminergic (VTADA) neurons during environmental stress, while LTA mice exhibit greater VTADA neurons activity under social stress. Viral tracing identifies the connectivity of VTADA neurons and anterior cingulate cortex (ACC). Optogenetic and chemogenetic manipulations demonstrate that VTA-ACC dopaminergic circuit is necessary and sufficient for VSDS-induced social avoidance behavior in HTA and LTA mice. RNA-sequencing suggested that VTA neuroinflammatory signaling may be a key factor contributing to the difference between HTA and LTA mice. Thus, this study reveals a neural circuit mechanism for trait anxiety-related observational learning of social avoidance behavior in male mice, and provides a molecular mechanism in shaping trait anxiety.","PeriodicalId":19143,"journal":{"name":"Neuropsychopharmacology","volume":"50 9","pages":"1364-1375"},"PeriodicalIF":6.6,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144288138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recently identified unique expression of proteins associated with epidermal skin cells (keratinocytes) and mechanosensory Merkel cells (MC) in circulating extracellular vesicles from adult women who had experienced sexual trauma specifically during adolescence, biologically linking trauma exposure with a specific neuron-like skin cell. Here, we aimed to develop and validate a preclinical mouse model utilizing chemogenetic (DREADD Gq) activation of a population of MC. Using a reporter line, we confirmed the expected pattern of the Krt14 Cre in specific MC skin areas and that these tissues expressed relevant MC marker genes similarly between male and female mice. Chemogenetic stimulation of MC produced robust neuronal activation of the insular cortex (IC), a brain region relevant to somatosensory and valence integration. To determine if the mice could detect MC activation, home cage behaviors following CNO treatment significantly increased nest grooming time. Conditioned place preference further revealed an avoidance response following MC stimulation; an effect that was stronger in female mice. Finally, to connect back to our trauma question, we examined MC activation in fear conditioning and identified deficits in fear extinction. Overall, these studies validate utilization of this preclinical model in further investigating the mechanosensory system and its potential involvement in PTSD symptoms and therapeutic interventions. Ongoing studies will focus on critical developmental periods relevant to both MC development and sex differences associated with trauma vulnerability and potential sensory based therapeutic options for PTSD-related symptoms.","PeriodicalId":19143,"journal":{"name":"Neuropsychopharmacology","volume":"50 9","pages":"1395-1405"},"PeriodicalIF":6.6,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41386-025-02144-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144251960","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}

The nucleus accumbens (NAc) represents a frequently targeted site in DBS interventions due to its demonstrated safety profile and therapeutic efficacy in obsessive-compulsive disorder, major depression, and anorexia nervosa. However, limited mechanistic understanding hampers its broader clinical applicability. This study sought to delineate the distinct behavioural dimensions modulated by NAc-DBS, its impact on distinct facets of memory, and to elucidate the underlying brain-network mechanism of action. We developed a novel spatial navigation task for rats and employed a high-dimensional behavioural analysis complemented by fMRI to dissect the cognitive, behavioural and neurobiological effects of NAc-DBS. Active NAc-DBS in male rats produced a selective enhancement of long-term memory encoding without affecting memory recall or working memory. We found a small but statistically significant rewarding effect of NAc-DBS, with no detectable impact on motor or stress-related behaviours. Sustained neuronal activation in the NAc, septum, entorhinal and insular cortex demonstrated no desensitisation to chronic NAc-DBS, which triggered a functional reorganisation among dopaminergic-related structures. These findings suggest that NAc-DBS induces a functional reorganisation in the mesocorticolimbic system, potentially mimicking a dopaminergic novelty signal to enhance memory updating. This provides a mechanistic basis for the therapeutic use of NAc-DBS, particularly in improving cognitive flexibility in psychiatric disorders.","PeriodicalId":19143,"journal":{"name":"Neuropsychopharmacology","volume":"50 9","pages":"1420-1429"},"PeriodicalIF":6.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41386-025-02132-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164607","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}

Cortical myelination occurs mostly on the proximal axons of parvalbumin positive (PV+) interneurons, where it assists in trophic support and experience-dependent plasticity. Given the role of PV+ interneuron dysfunction in SSD, it is critical to advance our understanding of cortical myelin pathology in this context. Here, we quantified myelin maps using the T1w/T2w ratio in a large group of antipsychotic medication-naïve, first-episode psychosis patients. We compared myelin content between patients (N = 91) and controls (N = 107) using a MANCOVA and calculated zero-order correlations with the discriminant function for each region, then used a machine learning approach to identify the most parsimonious constellation of cortical regions driving group differences using a stepwise algorithm. Group membership was significantly associated with T1w/T2w ratio (Wilks Lambda = 0.09, p < 0.01), where patients had higher myelin values compared to healthy controls. We identified a subset of 16 regions, primarily located in association cortices, that were sufficient to explain group differences. Here, we report an increase in the cortical T1w/T2w ratio in association cortices in first-episode psychosis. We suggest that faulty myelin compaction during this critical developmental period could contribute to PV+ interneuron pathology and cortical microcircuit disruptions resulting in the clinical phenotype. With additional empirical support from future studies, novel treatment strategies targeting cortical myelin could have potential to mitigate circuit dysfunction in the illness.","PeriodicalId":19143,"journal":{"name":"Neuropsychopharmacology","volume":"50 9","pages":"1439-1445"},"PeriodicalIF":6.6,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41386-025-02137-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144132041","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}

Traditional methods like color coding, tagging, and RFID tracking, while effective, have notable practical limitations. State-of-the-art neural network-based trackers often struggle to maintain individual identities in large groups for more than a few seconds. Fiducial tags such as ArUco codes present a potential solution to enable accurate tracking and identity management. However, their application to large groups of socially interacting mice in complex, enriched environments remain an open challenge. Here, we present the Tailtag system, a novel approach designed to address this challenge. The Tailtag is a non-invasive, safe, and ergonomic tail ring embedded with an ArUco marker allowing to track individual mice in colonies of up to 20 individuals in complex environments for at least seven days without performance degradation or behavioral alteration. We provide a comprehensive parameter optimization guide and practical recommendations for marker selection, for reproducibility across diverse experimental setups. Using data collected from Tailtag-equipped mice, we revealed the formation and evolution of social groups within the colony. Our analysis identified social hub regions within the vivarium where social contacts occur at different frequencies throughout one week of recordings. We quantified interactions and avoidance patterns between specific pairs of mice within the most active social hubs. Overall, our findings indicate that while the zone preferences and peer associations among the mice change over time, certain groups and pairwise interactions consistently form within the social colony.","PeriodicalId":19143,"journal":{"name":"Neuropsychopharmacology","volume":"50 9","pages":"1336-1345"},"PeriodicalIF":6.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41386-025-02126-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129902","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}

The present study investigated how the concurrent availability of non-drug reinforcers previously shown to be heroin substitutes or complements affected demand for heroin in rats. In Exp. 1, three groups of rats pressed one lever for intravenous heroin infusions on a series of prices that increased over sessions. The groups differed with respect to what they received for pressing a second lever: timeout-from-avoidance (TOA) reinforcers, heroin at a constant low price, or no programmed consequences. The essential value of heroin was significantly reduced in the groups that had either TOA or low-price heroin available on the second lever. Additionally, as the price of heroin on the first lever increased, consumption of TOA reinforcers or low-price heroin infusions increased, confirming that these were substitutes for expensive heroin. In Exp. 2, two groups of rats pressed one lever for heroin infusions on a series of increasing prices. One group could press a second lever for saccharin reinforcers at a constant low price. Concurrent saccharin availability increased demand for heroin in female rats, but not in male rats. Exp. 3 compared demand for saccharin in groups that had or did not have concurrent access to low-price heroin. Concurrent heroin availability caused an increase in estimated saccharin consumption at no cost (Q₀), but did not affect elasticity of demand for saccharin. The outcome of Exp. 1 suggests that non-drug means of reducing pain or stress can weaken demand for opioids. Exp. 2 and 3 show that, in contrast, availability of some non-drug alternatives can increase demand for heroin in female rats and that heroin can increase consumption of non-drug alternatives at low price.
