However, the interactive effects of these two developmental risk factors remain underexplored. The present study investigated the synergistic impact of PEE and adolescent binge-like ethanol exposure on behavioral and ethanol consumption patterns in Wistar rats. Pregnant dams received ethanol (2.0 g/kg/day) or vehicle from gestational days 17–20. Offspring were subjected to intermittent ethanol exposure (4.0 g/kg/day, two days on–two days off) or vehicle from postnatal days 23–36. Behavioral assessments included tests for anxiety-like behaviors (light–dark box test), anhedonia (sucrose preference test), exploratory behavior (multivariate concentric square field test), and voluntary ethanol consumption in early adulthood. PEE was associated with increased overall fluid consumption (p = 0.001, η<sup>2</sup>p = 0.17) and a sex-dependent increase in ethanol intake (p = 0.001, η<sup>2</sup>p = 0.05). PEE rats displayed reduced sucrose preference (p = 0.02, η<sup>2</sup>p = 0.07), suggesting an anhedonic-like phenotype independent of adolescent ethanol exposure. The latter exposure induced an anxious phenotype, characterized by reduced time in the illuminated compartment of the light–dark box test, which was attenuated in PEE-exposed rats (p = 0.03, η<sup>2</sup>p = 0.06). These findings suggest that PEE (a) facilitates ethanol consumption in offspring, potentially through tolerance mechanisms or altered chemosensory processing; and (b) modulates anxiety-like behaviors induced by adolescent ethanol exposure.

A dysfunctional blood–brain barrier (BBB) has been found to be influential in a number of brain disorders. The BBB is critical in maintaining homeostasis between the brain vasculature and parenchyma and a loss in barrier integrity would enable otherwise impermeable immune cells, molecules, and inflammatory mediators to reach the brain parenchyma. A subset of studies demonstrated that alcohol could diminish BBB integrity, but it is unclear if this effect translates clinically. In this study, we utilize a human stem cell-derived BBB model with near <em>in vivo</em> properties to investigate the effects of alcohol on critical barrier properties. Barrier forming brain-like microvascular endothelial cells (BMECs) were derived from human induced pluripotent stem cells (iPSCs) and exposed to several alcohol concentrations. Alcohol decreased barrier integrity observed by a loss in trans-endothelial electrical resistance and an increase in sodium fluorescein permeability. Alcohol decreased expression and junctional localization of tight junction proteins, a critical component to barrier integrity. Additionally, alcohol did not affect efflux transporter activity or cell viability in BMECs. The detrimental effects of alcohol on BBB properties were due to in part elevated reactive oxygen species (ROS); as scavenging ROS improved barrier properties, including the restoration of tight junction expression and localization. These data suggest that excessive alcohol consumption could diminish the BBB and contribute to the development or exacerbation of brain disorders.</div></div><div><h3>Clinical trial number and registry URL</h3><div>Not applicable.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"125 ","pages":"Pages 55-66"},"PeriodicalIF":2.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143788980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mice were tested with both traditional metal sippers and plastic sippers equipped with Hydropac® valves to assess differences in alcohol intake, preference, and total fluid consumption. Our findings revealed that mice displayed reduced intake and preference for alcohol (10–20% v/v) delivered via the Hydropac® containing plastic sippers. Notably, the effect was observed at both testing sites, suggesting a generalizable phenomenon. The decreased intake was also specific to alcohol, as water, quinine, and sucrose consumption were unaffected by sipper type. To investigate the underlying cause of the reduced alcohol consumption, we pre-incubated Hydropac® valves in 20% alcohol and found that the pre-treated alcohol reduced intake even when delivered via metal sippers. This suggests that prolonged interaction between alcohol and the components of the Hydropac® valves alter the fluid, likely by generating unpalatable contaminants. These results highlight a limitation of using plastic sippers in long-term alcohol self-administration studies.

These findings highlight the potential neuroprotective effects of tPA in maintaining hippocampal plasticity and mitigating stress-induced dysregulation of critical neurotrophic pathways.
