Outline of Final Research Achievements |
The menthol which activates TRPV3 and the capsaicin which activates TRPV1 induce inflammatory cytokines such as RANTES, TSLP and IL-33 in nasal polyps of eosinophilic chronic rhinosinusitis. On the other hand, antagonists of TRPV3 and TRPV1 suppress the expression of these inflammatory cytokines. Furthermore, transnasal administration of menthol and capsaicin induces eosinophil infiltration to nasal mucosa of mice. This results suggest that TRPV3 and TRPV1 may induce inflammatory cells such as eosinophils in the mucous membrane.
