Histologic examination of nasal mucosa in mice was done using hematoxylin-eosin staining to compare the degree of inflammation. Pro-inflammatory cytokine levels and TRPM8 expression levels were measured in mouse nasal lavage fluid.</p><p><strong>Results: </strong>In vitro experiments demonstrated that CA intervention in HNECs significantly reduced the protein and mRNA of IL-25, IL-33, TSLP, and TRPM8. In vivo analysis showed that the CA group exhibited fewer nose scratching and sneezing symptoms and reduced nasal mucosal inflammation as well as lower levels of IL-25, IL-33, and TSLP in nasal lavage fluid and tissues than the model group.</p>","PeriodicalId":7731,"journal":{"name":"American journal of translational research","volume":"16 12","pages":"7792-7802"},"PeriodicalIF":1.7,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11733383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
