While there are many commonalities in how men and women are impacted by AUD, an accumulating body of evidence is revealing sex-dependent adaptations that may require distinct therapeutic approaches. Preclinical rodent studies are beginning to shed light on sex differences in the effects of chronic alcohol exposure on synaptic activity in a number of brain regions. Prior studies from our laboratory revealed that, while withdrawal from chronic intermittent ethanol (CIE), a commonly used model of AUD, increased excitability in the ventral hippocampus (vHC) of male rats, this same treatment had the opposite effect in females. A follow-up study not only expanded on the synaptic mechanisms of these findings in male rats, but also established a CIE-dependent increase in the excitatory-inhibitory (E-I) balance of a glutamatergic projection from the basolateral amygdala to vHC (BLA-vHC). This pathway modulates anxiety-like behavior and could help explain the comorbid occurrence of anxiety disorders in individuals suffering from AUD. The present study sought to conduct a similar analysis of CIE effects on both synaptic mechanisms in the vHC and adaptations in the BLA-vHC pathway of female rats. Our findings indicate that CIE increases the strength of inhibitory neurotransmission in the vHC and that this sex-specific adaptation blocks, or at least delays, the increases in intrinsic vHC excitability and BLA-vHC synaptic transmission observed in males. Our findings establish the BLA-vHC pathway and the vHC as important circuitry to consider for future studies directed at identifying sex-dependent therapeutic approaches to AUD.</p></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"32 ","pages":"Article 100665"},"PeriodicalIF":4.3,"publicationDate":"2024-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352289524000614/pdfft?md5=90039c322dcf18fccf524ceba4252eb5&pid=1-s2.0-S2352289524000614-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141979597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The association of fetal BDNF with newborn anthropometrics was tested.</p></div><div><h3>Methods</h3><p>Women near term who underwent elective cesarean section and their newborns were investigated (n = 37). Maternal psychometrics, socioeconomic status and glucocorticoids (the sum of cortisol and cortisone) in amniotic fluid at birth were analyzed for an association with fetal BDNF in amniotic fluid at birth. Newborn anthropometrics were assessed by length, weight, head circumference and gestational age at birth.</p></div><div><h3>Results</h3><p>In bivariate analysis, maternal psychometrics and socioeconomic status were not related to fetal BDNF in amniotic fluid at birth. The sum of cortisol and cortisone related to increased fetal BDNF in amniotic fluid at birth (r = 0.745, p &lt; 0.001). BDNF in amniotic fluid was associated negatively with fetal birth weight per gestational age (r = −0.519, p &lt; 0.001), length per gestational age (r = −0.374, p = 0.023), head circumference per gestational age (r = −0.508, p = 0.001), but not with gestational age at birth. In multiple regression analysis, the sum of cortisol and cortisone (p &lt; 0.001) and birth weight per gestational age (p = 0.012) related to higher fetal BDNF levels in amniotic fluid at birth (R<sup>2</sup> = 0.740, p &lt; 0.001) when controlling for fetal sex and maternal age. Head circumference per gestational age predicted fetal BDNF with borderline significance (p = 0.058) when controlling for confounders.</p></div><div><h3>Conclusion</h3><p>Glucocorticoids in amniotic fluid were positively associated with high fetal BDNF at birth, which may be an adaptive fetal response. Maternal psychological variables and socioeconomic status did not link to fetal BDNF. Birth weight and head circumference per gestational age were inversely associated with fetal BDNF at birth, which may represent a compensatory upregulation of BDNF in fetuses with low anthropometrics. Longitudinal studies are needed to assess the role of stress during pregnancy on later offspring development. The analysis of additional fetal growth factors and inflammation upon maternal stress in further biomaterials such as the placenta is warranted, to understand mechanistic alterations of how maternal stress links to fetal development and an increased vulnerability for psychopathology.</p></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"31 ","pages":"Article 100658"},"PeriodicalIF":4.3,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352289524000547/pdfft?md5=9e9ab289fa08eaeadbeb0e91aa7d0e6f&pid=1-s2.0-S2352289524000547-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141587972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using male CRF1:GFP reporter mice, we recently reported that CRF1-expressing (mPFC<sup>CRF1+</sup>) neurons predominantly comprise mPFC prelimbic layer 2/3 pyramidal neurons, undergo profound adaptations following chronic ethanol exposure, and regulate anxiety and conditioned rewarding effects of ethanol. To explore the effects of acute and chronic ethanol exposure on glutamate transmission, the impact of chronic alcohol on spine density and morphology, as well as persistent changes in dendritic-related gene expression, we employed whole-cell patch-clamp electrophysiology, diOlistic labeling for dendritic spine analysis, and dendritic gene expression analysis to further characterize mPFC<sup>CRF1+</sup> and mPFC<sup>CRF1−</sup> prelimbic layer 2/3 pyramidal neurons. We found increased glutamate release in mPFC<sup>CRF1+</sup> neurons with ethanol dependence, which recovered following withdrawal. In contrast, we did not observe significant changes in glutamate transmission in neighboring mPFC<sup>CRF1−</sup> neurons. Acute application of 44 mM ethanol significantly reduced glutamate release onto mPFC<sup>CRF1+</sup> neurons, which was observed across all treatment groups. However, this sensitivity to acute ethanol was only evident in mPFC<sup>CRF1−</sup> neurons during withdrawal. In line with alterations in glutamate transmission, we observed a decrease in total spine density in mPFC<sup>CRF1+</sup> neurons during dependence, which recovered following withdrawal, while again no changes were observed in mPFC<sup>CRF−</sup> neurons. Given the observed decreases in mPFC<sup>CRF1+</sup> stubby spines during withdrawal, we then identified persistent changes at the dendritic gene expression level in mPFC<sup>CRF1+</sup> neurons following withdrawal that may underlie these structural adaptations. Together, these findings highlight the varying responses of mPFC<sup>CRF1+</sup> and mPFC<sup>CRF1−</sup> cell-types to acute and chronic ethanol exposure, as well as withdrawal, revealing specific functional, morphological, and molecular adaptations that may underlie vulnerability to ethanol and the lasting effects of ethanol dependence.</p></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"31 ","pages":"Article 100657"},"PeriodicalIF":5.0,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352289524000535/pdfft?md5=f008065f33ec9effa93d55f47a20ceee&pid=1-s2.0-S2352289524000535-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141334969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
