Significant alterations in the gut microbiome occur in AUD even before any other systemic signs or symptoms manifest. Prolonged and inappropriate alcohol consumption, by affecting the gut microbiota and gut mucosa permeability, is thought to contribute to the development of behavioral and cognitive impairments, leading to Alcohol-Related Liver Disorders and potentially progressing into alcoholic cirrhosis, which is often associated with severe cognitive impairment related to neurodegeneration, such as hepatic encephalopathy and alcoholic dementia.</div><div>The critical role of the gut microbiota is further supported by the efficacy of FDA-approved treatments for hepatic encephalopathy in alcoholic cirrhosis (i.e., lactulose and rifaximin).

Early identification of AUD individuals at risk for developing these conditions could help to prioritize integrated therapeutic interventions targeting different substrates of the Gut Microbiome-Liver-Brain axis. Specifically, addiction medications, microbiome modulators, stress-reducing interventions, and, possibly soon, novel agents that reduce hepatic steatosis/fibrosis will be discussed in the context of digitally supported integrated therapeutic approaches.

This disrupted signaling consequently alters the balance of synapse formation, maturation and pruning, processes which regulate neural communication, plasticity, learning, cognitive flexibility and adaptive behaviors - hallmarks of a healthy, functional brain. The chronically stressed brain state, therefore, is one which may be uniquely vulnerable. To understand the development of this state, how it is sustained and how behavior and neural function are transiently or indelibly impacted by it, we can turn to a number of advanced approaches in animal models which offer unprecedented insights. This has been the aim of my recent work within the field and the goal of my new independent research program. To achieve this, I have employed methods to uncover how key brain circuits integrate information to support motivated behaviors, how stress impacts their ability to perform this process and how best to operationalize behavioral readouts.

The defensive burying behavior of rodents is a response to imminent threats that becomes markedly pronounced in response to anxiety. However, the neural foundations of defensive burying behavior and etiology of anxiety remain largely unknown. In this study, we established a model employing object binding to elicit increased burying behavior in mice, thereby enhancing fear resolution and subsequently reducing anxious behaviors. Notably, the mice that associated shock with an object exhibited less object exploration and the zona incerta (ZI) neurons showed higher calcium activity during object exploration as compared to the Shock only mice. Although the calcium activity in ZI neurons of the Object mice was identical to the Shock only mice, the Object mice exhibited more burying behavior. Furthermore, the time spent in the center of the open-field test was directly proportional to the duration of burying behavior. Chemogenetic activation of ZI neurons extended the burying time and concomitantly ameliorated anxiety-like behavior. Importantly, chemogenetic enhancement of projection from ZI neurons to the ventral periaqueductal gray (vPAG), a brain region that plays a critical role in autonomic function, normalizes anxious behavior without influencing burying behavior. Collectively, these findings systematically reveal the functions and underlying mechanisms of the ZI-vPAG circuit in controlling behaviors akin to anxiety, offering significant insights into ZI's role in the pathophysiology of anxiety disorders.</div></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"34 ","pages":"Article 100704"},"PeriodicalIF":4.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143140572","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}

Most research on active avoidance has focused on the behavioral and neurobiological processes when individuals learn to avoid alone, within a solitary context. Therefore, little is known about how social context affects active avoidance. Using a modified version of the platform-mediated avoidance task in rats, we investigated whether the presence of a social partner attenuates conditioned freezing and enhances avoidance compared to avoidance in a solitary context. Rats spent a similar amount of time avoiding during either context; however, rats trained in the social context exhibited greater freezing as well as lower rates of darting and food seeking compared to rats trained in the solitary context. In addition, we observed higher levels of avoidance in females compared to males in the solitary context, but this sex difference was not present in rats trained in the social context. To gain greater mechanistic insight, we optogenetically inactivated glutamatergic projection neurons in the anterior cingulate cortex (ACC) following avoidance training in either context. After avoidance was learned in a social context, photoinactivation of ACC reduced expression of avoidance during a test when the social partner was absent, but not when the partner was present. Our findings suggest a novel contribution of the ACC in avoidance that is learned with a social partner, which has translational implications for understanding ACC dysfunction in those suffering from trauma-related disorders.</div></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"34 ","pages":"Article 100702"},"PeriodicalIF":4.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11683269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906685","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}

These results provide further insight into the genetically controlled biological and environmental factors underlying the shared etiology between PTSD and migraine.

Studies have shown that corticosterone (CORT)-induced PPD affects neurogenesis in the offspring, which is closely related to the onset of depression. However, the underlying mechanisms of these changes in the offspring of PPD mothers remain unexplored. In this study, we demonstrated postpartum mice treated with high CORT experienced activation of the hypothalamic-pituitary-adrenal (HPA) axis, which induced depressive-like behavior and impaired maternal caring behavior. Furthermore, adolescent offspring of PPD mice exhibited depression-like behavior, and learning and memory deficits. These offspring also showed diminished levels of DCX⁺, decreased levels of synaptic proteins, and reduced dendritic spine density and length in hippocampus. Additionally, we detected increased serum stressed hormones and decreased hippocampal glucocorticoid receptor (GR) protein level in the offspring. We also found the offspring exhibited reduced expression of brain-derived neurotrophic factor (BDNF) and the phosphorylation tyrosine kinase receptor B (TrkB), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) proteins in hippocampus. These results indicated that the behavioral deficits and neuronal damage observed in the offspring of PPD mice may be related to HPA axis dysfunction and inhibition of the BDNF-mTOR pathway. In conclusion, our findings confirm that CORT induces depression-like behavior and impairs maternal caring behavior in maternal mice, which in turn affects their offspring's emotion and cognitive behavior.

A factor analysis conducted on stress reactivity measures yielded two factors: one composed of reactivity in heart rate, heart rate variability, and cortisol, and one composed of reactivity in skin conductance and self-reported mood. These two factors independently moderated the associations between early unpredictability and subsequent emotional problems. For each factor, the combination of higher unpredictability and higher stress reactivity predicted higher emotional problems; stress reactivity factors were not significant moderators of the effects of threat and deprivation.
