The molecular identification was done using quantitative real-time PCR and immunohistochemistry for serotonin 5HT-1B receptor in rat brains.</p><p><strong>Results: </strong>Interestingly, the 5HT-1B receptor, one of the most important serotonin receptors, exhibits a sex-dependent difference in stress response in male and female rats. Most importantly, the trio partners (amygdala, hippocampus, and prefrontal cortex) exhibit a region-specific sex dependent difference in 5HT-1B receptor expression, which was correlated with the difference in the level of stress response. This biased serotonin 5HT-1B receptor function might be why females face more stress than males.</p><p><strong>Conclusion: </strong>Overall, the results exhibit a sex-dependent difference for stress conditions in male and female rats, which was correlated with the spatial expression of the serotonin 5HT-1B receptor in the brain.</p>","PeriodicalId":8701,"journal":{"name":"Basic and Clinical Neuroscience","volume":"16 1","pages":"81-94"},"PeriodicalIF":1.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12248184/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
