Early life stress (ELS), which includes factors such as inadequate parental care and childhood abuse, significantly increases the risk of developing neuropsychiatric disorders, including anxiety and depression. This review examines the impact of maternal separation (MS) on depression, anxiety and pain behaviour, with a particular emphasis on neuroinflammatory pathways. Experiences of ELS can adversely affect the maturation of neurotransmitter systems and associated neural circuits that are crucial for processing painful stimuli and regulating anxiety and depression. Stressful experiences trigger inflammatory processes in the brain, initiating immune responses in neural cells and stimulating the production of pro-inflammatory cytokines. In mammals, MS serves as a significant stressor that activates the hypothalamic–pituitary–adrenal (HPA) axis and other stress-related systems, leading to increased immune challenges and heightened pain sensitivity in adulthood due to systemic inflammation. Key inflammatory mediators, such as IL-1β, IL-6 and TNF-α, play critical roles in the development of pathological pain, while the activation of microglia releases inflammatory mediators that contribute to neurological dysfunction and the pathophysiology of stress, depression and anxiety. Moreover, therapeutics targeting oxidative stress and inflammation have shown promise in alleviating affective disorders following MS. This review discusses potential pathways, with a primary focus on neuroinflammatory mechanisms and the therapeutic strategies that may mitigate the adverse effects of MS. There is a pressing need for further research to elucidate the underlying pathways and identify effective interventions to improve mental health outcomes in individuals affected by MS.</p>\u0000 </div>","PeriodicalId":13914,"journal":{"name":"International Journal of Developmental Neuroscience","volume":"85 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143079778","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}

This study aimed to investigate the neuroprotective effects of Edaravone (EDA), a free radical scavenger, and elucidate the potential role of brain-derived neurotrophic factor (BDNF) in mediating these effects in neonatal HIE rats. Using the Rice-Vannucci model, HIE was induced in neonatal rats, followed by immediate administration of EDA after the hypoxic–ischemic insult. To examine the role of BDNF, a separate group of rats received intrahippocampal injections of a lentiviral vector for BDNF knockdown prior to the induction of HIE and subsequent EDA treatment. Neuronal survival and apoptosis in the hippocampal region were assessed by immunofluorescence and TUNEL staining, respectively. BDNF expression levels in the hippocampus were analysed using enzyme-linked immunosorbent assay (ELISA). Cognitive function was evaluated using the Morris water maze (MWM) and Y maze tests. Results demonstrated that EDA significantly reduced hippocampal neuronal apoptosis and death, increased neuronal survival, and enhanced BDNF expression compared to the control group. However, the therapeutic effects of EDA were mitigated in the BDNF knockdown group, indicating a crucial role of BDNF in mediating the neuroprotective effects of EDA. Behavioural testing confirmed that EDA treatment significantly improved spatial learning and memory abilities in HIE rats, but these improvements were not observed in rats with BDNF knockdown. In conclusion, our study suggests that EDA treatment mitigates hippocampal neuronal death and improves cognitive dysfunction in HIE rats primarily by upregulating BDNF expression. These findings provide experimental support for the potential application of EDA in the treatment of HIE and highlight the essential role of BDNF in neuroprotection and cognitive recovery post-HIE.</p>\u0000 </div>","PeriodicalId":13914,"journal":{"name":"International Journal of Developmental Neuroscience","volume":"85 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004912","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}
