Because several types of cells play a role in pathogenesis, ECRS is a heterogenous disease. To identify each cell function is important for the individualization of therapy. The eosinophil is a granulocyte that contain eosinophil granule proteins (EGPs). EGPs have antiparasitic activity, on the other hand, closely related allergic inflammation due to its cytotoxicity. Eosinophil-derived neurotoxin (EDN) is one of the eosinophil granule proteins. In this study, we evaluated the function of EDN in ECRS pathogenesis. Serum EDN levels were significantly higher in patients with ECRS than in those with other nasal and paranasal diseases and were positively correlated with clinical disease activity. EDN expressed in the eosinophils of ECRS nasal polyps. Human nasal epithelial cells (HNEpCs) were stimulated with EDN, and the resultant changes in gene expression were detected by RNA sequencing. Pathway analysis revealed that the major canonical pathway affected by EDN stimulation was “regulation of the epithelial–mesenchymal transition (EMT) pathway”; the only gene in this pathway to be up-regulated was matrix metalloproteinase 9 (MMP-9). EDN may be involved in the pathogenesis of ECRS and also be an important therapeutic target.","PeriodicalId":204414,"journal":{"name":"Journal of Japan Society of Immunology & Allergology in Otolaryngology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127718594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NO production is regulated by activities of three isoforms of nitric oxide synthase (NOS) and bioavailability of L-arginine as a substrate. We consider measuring FeNO can be a valid marker to differentiate chronic rhinosinusitis (CRS) phenotypes based on distinct difference in arginase and NOS isoform activities. Although previous studies have reported that nasal NO levels generally decreased in CRS patients, the usefulness of NO measurement remains controversial. We found that eosinophilic CRS (ECRS) patients showed higher oral FeNO levels compared to non-ECRS patients. The increased FeNO levels in the ECRS patients are possibly related with augmented inducible NOS (NOS2) expression and airway eosinophilia. In addition, the role of endothelial NOS (NOS3) in nasal polyp formation has been proposed. NOS3 expression was found to be in glands, epithelial and vascular endothelial cells, the positive staining of which accounting for secretion and vascular dilatation. NOS2 gene expression is predominantly transcriptionally regulated. The existence of NOS2 promoter gene polymorphisms may influence CRS pathophysiology as shown in asthmatic patients. As for NOS3, several stimuli have been shown to initiate or enhance the enzyme activity and consequently the NO production both in calcium-dependent and -independent manners. The post-translational modification such as phosphorylation also influences eNOS activities. Further studies are needed in order to clarify the deeper role of the NOS isoforms in the pathogenesis of CRS phenotypes.","PeriodicalId":204414,"journal":{"name":"Journal of Japan Society of Immunology & Allergology in Otolaryngology","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114304258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
