One possible mechanism is that ACEs alter the neural correlates responsible for the preferential processing unpleasant stimuli, a key feature of anxiety. Another mechanism could be a stress-induced disruption in the processing of pleasant stimuli, which is mostly linked with depressive symptoms. In this study, we examined how ACEs and neural correlates of different emotional processing stages (affective engagement, anticipation, elaboration) interact in the association with internalizing symptoms in a sample of university students (<em>n</em> = 46, 28 females). Participants completed the Adverse Childhood Experiences Questionnaire (ACE-Q), and the anxiety and depression subscale of the Brief Symptoms Inventory Checklist to assess depression and anxiety. An S1-S2 paradigm, a task in which a cue (S1) anticipates the valence of a succeeding emotional image (S2), was used during an electroencephalographic (EEG) recording. Three event-related potentials (ERPs) reflecting different stages of emotional processing were assessed: the Cue-P300 (reflecting cue-evaluation and affective engagement), the Stimulus Preceding Negativity (SPN; reflecting outcome anticipation), and the P300/late positive potential (LPP) complex (reflecting affective processing). ACEs were linked to greater P300/LPP for unpleasant stimuli, suggesting that childhood adversities may be related to increased elaboration of threatening information. Moreover, ACEs were associated with dampened engagement (Cue-P300) and processing (P300/LPP) of pleasant content. Interestingly, the interaction between the P300/LPP to unpleasant stimuli and ACEs was significantly associated with greater symptoms of anxiety, whereas there was no effect in the link with depression. Specifically, individuals exposed to ACEs only reported heightened anxiety symptoms when their P300/LPP complex to unpleasant stimuli was larger. No significant effect emerged for the other ERPs components. Taken together, these findings suggest that an increased sensitivity to unpleasant content in adulthood might moderate the association between ACEs and anxiety symptoms.</div></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"37 ","pages":"Article 100740"},"PeriodicalIF":4.3,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stress and trauma exposure are among the strongest predictors of youth mental health problems; however, most children and adolescents remain resilient despite such exposures. The widespread and heterogeneous challenges posed by the COVID-19 pandemic offer a unique opportunity to examine, at scale, who develops mental health problems under stress and who remains resilient. Integrating emerging findings on pandemic-related risk and protective factors with evidence from animal models can illuminate sensitive developmental periods of heightened susceptibility to environmental influence and biological embedding. This approach can identify when, how, and through what pathways mental health problems emerge, including gene–environment interactions and epigenetic mechanisms.

These signalling molecules integrate environmental cues into neurobiological responses by regulating gene and protein expression in a cell-type-specific manner. Specifically, neuroactive steroids and neuropeptides modulate the hypothalamic-pituitary-adrenal axis to influence excitatory/inhibitory balance in the brain and broadly impact mood, cognition, and memory. Despite their central role in brain function, these signalling systems remain historically understudied, exposing a major gap in our understanding of stress-related psychiatric disorders, and posing a valuable opportunity for therapeutic innovation. Foundational studies using histology, genetic manipulation, and bulk transcriptomic approaches, primarily in rodent models, have provided critical insights into their roles. However, these traditional methods lack the resolution to capture region- and cell-specific mechanisms, which are needed to develop precision medicine approaches. The emergence of single-cell and spatial technologies now offers unprecedented insight into the precise cellular, molecular and spatial context in which neuroactive steroid and neuropeptide signalling occurs. By moving beyond cell-type-averaged measures, these tools enable detailed mapping of transcriptional and proteomic changes across specific brain areas and cell-types, helping to identify the microenvironments in which these systems become dysregulated.

The relationship of the synaptic plasticity and learning and memory with the hypothalamus-pituitary-adrenal (HPA) axis and the integrity of blood-brain and intestinal barriers were also examined. The experimental subjects were introduced to probiotic treatment to assess how the supplementation influences stress-related alterations. The prenatal stress effectively impaired both LTP occurrence and behavioral function. It also led to disruption of blood-brain and gut barriers and increased serum level of corticosterone. The probiotic supplementation positively affected the synaptic plasticity and learning and memory. It also improved the integrity of both barriers and reduced the stress hormone corticosterone. Whereas there is a reverse relationship between stress and the hippocampus-dependent spatial memory, normal stress hormone, and the integrity of intestinal and brain barriers, the probiotic supplements improve all impairments.

PTSD negatively impacts 6 % of people during their lifetime, with women being disproportionally affected and exhibiting different, more severe symptoms than men. Despite this widespread impact, the molecular mechanisms underlying PTSD and its sex differences remain poorly understood. Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) is a neuropeptide which participates in fine-tuning circuitry throughout the brain and has been associated with PTSD in humans, especially in women. Here, we use Single Prolonged Stress (SPS), an animal model of PTSD, to explore the roles of PACAP and sex in PTSD-like behaviors. Specifically, a PACAP agonist or antagonist was infused into the infralimbic (IL) prefrontal cortex, a region key to regulating fear- and anxiety-related behaviors, prior to SPS in male and female rats. Rats were then tested in open field/novel object, elevated plus maze, and social interaction. Utilizing a behavioral indexing method, we were able to uncover SPS effects in PTSD-related behavioral domains that were differentially impacted by PACAP manipulations in males and females. While both sexes exhibited increased threat avoidance and decreased threat assessment following SPS, females increased sociability while males decreased sociability. Males also appeared to be protected by IL PACAP antagonism while female SPS phenotypes were exacerbated by IL PACAP agonism. Furthermore, RNAscope revealed that PACAP in the prefrontal cortex responds differently to SPS in males and females. Together, these findings suggest complex relationships between SPS, sex, and IL PACAP which may have important implications for treating PTSD in men and women.</div></div>","PeriodicalId":19125,"journal":{"name":"Neurobiology of Stress","volume":"36 ","pages":"Article 100727"},"PeriodicalIF":4.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
