| Outline of Final Research Achievements |
The number of patients with eosinophilic chronic rhinosinusitis (ECRS) tends to be increased in recent years in Japan. Whole transcriptome analysis with next generation sequencer (RNA-seq) was conducted to investigate molecular biological mechanism of ECRS. RNA-seq showed that 3 genes were significantly highly expressed in nasal polyps of ECRS. In these genes, TRPV3 (transient receptor potential cation channel, subfamily V, member 3) was the only gene which is not expressed in peripheral blood eosinophils.
Further study showed that TRPV3 was highly expressed in infiltrating eosinophils and mucosal epithelium of nasal polyps of ECRS. This results suggested that TRPV3 may play a role of refractoriness of ECRS.
