Outline of Final Research Achievements

To investigate the distribution, phenotypes, and immunoglobulin E (IgE) positivity of mast cells in these 2 subtypes of Chronic rhinosinusitis with nasal polyps (CRSwNP).
Expression of tryptase mRNA was significantly increased in nasal polyps from patients with the 2 subtypes of CRSwNP compared with controls. Immunohistochemistry showed increased numbers of tryptase-positive mast cells in the epithelium, glands, and submucosa of ECRS polyps, whereas the number
of tryptase- and chymase-positive mast cells was increased in the glands and submucosa of non-ECRS polyps. IgE-positive mast cells were abundant in the epithelial, glandular, and submucosal regions of ECRS polyps but few were detected in non-ECRS polyps. The present study demonstrates that the distribution, subtype population, and IgE positivity of mast cells is different between ECRS and non-ECRS nasal polyps. Our results suggest a role for IgE-mediated mast cell activation in the pathogenesis of ECRS.
