The gut–brain axis (GBA) is a bidirectional signaling process that permits feedback between the brain and gut and is altered in subjects with opioid use disorders, but the spatiotemporal correspondence between quantitative translational measures of gut and brain health is not clear. In this work, we determined longitudinal and concurrent changes in the brain and gut of rodents trained to self-administer morphine for 14 days. Active lever presses delivered a single infusion of morphine (0.4 mg/kg/infusion). We used MRI and 16s rDNA analysis of faecal matter to identify changes from baseline (naïve, nondrug state) to an acute phase (early in the self-administration process, after 2 days of self-administration) and a chronic phase (late in the self-administration process, after 14 days of self-administration). Animals were scanned in a 7T MRI scanner three times (baseline, acute and chronic), and before scanning, faecal matter was collected from each rat. We found early changes in gut microbiota diversity and specific abundance as early as the acute phase that persisted into the chronic phase. In MRI, we identified alterations in diffusivity indices both within subjects and between groups, showing a main effect in the striatum and thalamus. We posit that gut changes precede the effects observed in MRI, with the striatum and thalamus emerging as crucial links mediating communication between the gut and the brain.</p>","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"30 6","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adb.70059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preclinical investigations into addiction heavily rely on animal models to explore the underlying biological mechanisms of addictive disorders, with a particular emphasis on understanding the etiological factors influencing drug intake.

This study systematically reviews the impact of ovarian hormones on the consumption of psychoactive substances in rodents, adhering to the PRISMA 2009 protocol. Our findings underscore the significant role of ovarian hormones, particularly oestrogen, in augmenting drug consumption among female rodents. Notably, with heroin, it was observed that progesterone, rather than oestrogen, facilitated increased consumption in female rodents. The susceptibility to addiction influenced by oestrogen is accentuated across distinct phases, and the molecular mechanisms form a complex interplay that significantly influences addictive behaviours. By bringing together these findings, we aim to establish a strong foundation for future studies.

Most hospitals in Japan lack specialized treatment units or psychiatrists for managing alcohol use disorders, leaving hepatologists to handle various aspects of the disease—a challenging task. This study retrospectively investigated the outcomes of alcoholic hepatitis in a typical Japanese hospital setting, stratified by ACLF diagnosis and other features, with the aim of identifying areas for possible improvement. We conducted a retrospective analysis of 88 patients hospitalized with alcoholic hepatitis, reviewing records for the diagnosis of ACLF or related conditions, development of delirium tremens (DT), risk factors, and patient outcomes. Patients meeting the Japanese criteria for ACLF or related conditions had significantly worse survival outcomes. DT developed in 13 patients, with low platelet counts and elevated γ-glutamyl transpeptidase levels identified as risk factors. Prophylactic oral benzodiazepines were found safe and significantly associated with preventing DT. Onset of DT during hospitalization did not measurably impact survival prognosis, but DT patients showed a tendency to break contact with our hospital and critical events may have been missed. While under hepatologist care, patients typically maintained sobriety, but relapse into alcohol-related health problems frequently occurred after follow-up was discontinued. In Japan, hepatologists may be missing important events with alcoholic hepatitis after follow-up discontinuation, especially in patients with DT. Therefore, integrated and collaborative care, particularly a psychosocial approach providing behavioural support, may reduce risk of relapse and improve patient prognosis.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Trial Registration:</h3>\u0000 \u0000 <p>All study protocols were reviewed and approved by the ethics committee at Fujita Health University School of Medicine (approval no.

The aim of this study was to investigate neuroinflammation, neuronal damage and potential changes in the orexin system or beta-amyloid metabolism in the cerebrospinal fluid (CSF) of individuals undergoing opioid substitution therapy (OST). This cross-sectional study investigates CSF biomarkers in individuals undergoing OST, compared to control subjects. Participants receiving OST were recruited from the outpatient clinic at the Department of Psychiatry, Sahlgrenska University Hospital, Gothenburg (Sweden). Each participant provided a complete medical history, including details of drug use over the past 6 months, followed by a lumbar puncture to obtain CSF samples. Molecules associated with neuroinflammation, neuronal and glial damage, beta-amyloid metabolism and orexinergic function were analysed in the participants' CSF, alongside electrolyte levels. Specifically, we analysed levels of sTREM-2, YKL-40, IL-1β, IL-6, IL-8, IL-10, TNF-α, AXL, MER, TYRO3, GAS6, NfL, GFAP, total tau (T-tau), phosphorylated tau (P-tau), neurogranin, Aβ40, Aβ42, the Aβ42/Aβ40 ratio, orexin-A, sPDGFR-β and electrolytes. The study included 15 control subjects and 17 in the opioid substitution group. Patients undergoing opioid substitution therapy exhibited elevated levels of sTREM-2, Aβ42/Aβ40 ratio and NfL in their CSF. Conversely, concentrations of Na⁺ and Cl⁻ were lower compared to controls. No significant differences were found between groups for other biomarkers, including orexin-A. However, when normalized to Aβ40 levels, YKL-40, IL-8, TYRO3 and P-Tau were also elevated in individuals with opioid dependence. Elevated biomarkers of neuroimmune activation, neuronal damage and beta-amyloid metabolism in opioid dependence suggest CNS inflammation as a contributor to its pathophysiology. Reduced electrolyte levels imply disrupted CSF water regulation, possibly linked to impaired glial function.

This systematic review is aimed at reviewing the evidence regarding the safety and efficacy of CBD as a therapeutic option in opioid use disorder (OUD) treatment in clinical and preclinical studies. We searched MEDLINE, Embase, PsycINFO, Scopus, Web of Science, CDSR and CENTRAL up to December 2023. We included original peer-reviewed human and animal studies evaluating CBD for OUD outcomes and excluded those that did not report OUD outcomes or used CBD solely with THC. The risk of bias was assessed with the Cochrane risk-of-bias tool for human studies and SYRCLE's tool for animal studies. Due to outcome heterogeneity, findings were presented using a qualitative synthesis. Four clinical studies (74 participants) and 16 preclinical studies met the inclusion criteria. The collective evidence from clinical and preclinical studies indicates that CBD holds promise as an adjunctive therapy for OUD with a well-tolerated profile during opioid use and withdrawal. Human clinical studies demonstrated a reduction in craving and alleviation of abstinence-induced anxiety. In preclinical studies, CBD has been shown to reduce withdrawal symptoms and diminish opioid-rewarding effects using the conditioned place preference paradigm, although the results are mixed, and not all preclinical studies reported these effects. The quality assessment for clinical studies indicated an overall evaluation of ‘some concerns’, while a notable level of ‘unclear’ risk was observed across the evaluated domains for preclinical studies. This systematic review highlights the potential of CBD as a beneficial treatment option for addressing cravings and anxiety symptoms during abstinence in individuals with OUD, based on findings from human studies. Continued research and clinical trials will be essential for further improving outcomes in OUD treatment using novel effective treatment approaches. Study limitations include the limited number of clinical studies, small sample size, short-term follow-up, lack of combination therapy and heterogeneity across preclinical studies.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Trial Registration</h3>\u0000 \u0000 <p>PROSPERO identifier: CRD42023401446</p>\u0000 </section>\u0000 </div>","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"30 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adb.70047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigated the preclinical evidence for tideglusib, a clinically available selective GSK3β inhibitor, in modulating chronic and binge ethanol consumption. Tideglusib decreased ethanol consumption in both a model of daily, progressive ethanol intake (two-bottle choice, intermittent ethanol access) and binge-like drinking behaviour (drinking in the dark) without effecting water intake. With drinking in the dark, tideglusib was more potent in males (ED50 = 64.6, CI = 58.9–70.8) than females (ED50 = 79.4, CI = 70.8–93.3). Further, we found tideglusib had no effect on ethanol pharmacokinetics, taste preference or anxiety-like behaviour, although there was a transient increase in total locomotion following treatment. Additionally, tideglusib treatment did not alter liver function as measured by serum activity of alanine aminotransferase and aspartate aminotransferase but did cause a decrease in serum alkaline phosphatase activity. RNA sequencing analysis of tideglusib actions on ethanol consumption revealed alterations in genes involved in synaptic plasticity and transmission, as well as genes downstream of the canonical Wnt signalling pathway, suggesting tideglusib may modulate ethanol consumption via β-catenin binding to the transcription factors TCF3 and LEF1.

The phase–amplitude coupling (PAC) can capture interactions between these frequencies and may be a more sensitive quantitative indicator for characterizing abnormal neural oscillations in smokers. We monitored the electroencephalography (EEG) data of 30 young smokers during a cue task after 12 h of abstinence, dividing the data into the neutral and smoking-related groups based on different experimental stimuli to analyse the relationship between PAC and craving. In addition, we computed the functional connectivity (FC) under the PAC mechanism. The results showed that the young smokers exposed to smoking-related cues under short-term abstinence conditions had significantly lower PAC values and reduced FC strength in the right prefrontal cortex. In contrast, there was a significant increase in PAC values in the parietal cortex and enhanced FC strength. The correlation analysis showed significant correlations between PAC values and craving.

Furthermore, a significant positive correlation was observed between the total score of Cannabis Use Disorders Identification Test at FU and the CT of left lateral OFC.
