Expression of prostaglandin D2 synthase in activated eosinophils in nasal polyps.
OBJECTIVE To clarify the relationship between prostaglandin D2 production and eosinophil accumulation. DESIGN Screening and diagnostic tests. SUBJECTS Nineteen patients with chronic rhinosinusitis. INTERVENTIONS Nasal polyps were obtained from 19 patients at endoscopic sinus surgery. Eosinophils in nasal polyps were counted after hematoxylin-eosin staining and immunostaining with antibodi...
متن کاملIntercellular adhesion molecule-1 expression in activated eosinophils is associated with mucosal remodeling in nasal polyps
Nasal polyposis (NP) is characterized by chronic mucosal inflammation with infiltrating eosinophils. Eosinophil‑mediated tissue remodeling may be involved in NP pathogenesis; therefore, improved understanding of tissue remodeling may result the identification of novel pathways and therapeutic strategies. The present study aimed to investigate the pathological changes occurring during tissue rem...
متن کاملIntranasal steroids decrease eosinophils but not mucin expression in nasal polyps.
Increased mucin expression is a feature of nasal polyposis. Corticosteroids reduce polyp size and symptoms, but their effect on mucin production remains unknown. In this study, the effects of intranasal corticosteroids on MUC5AC mucin expression, nasal resistance, eosinophil and neutrophil infiltration, epidermal growth factor receptor (EGFR), interleukin (IL)-8, and tumour necrosis factor (TNF...
متن کاملEpidemiology of Nasal Polyps
Mounting evidence suggests that nasal polyposis (NP) is a clinical manifestation of multiple possibly coexisting immunologic pathways, and because this entity likely reflects an array of disease states, the epidemiology is difficult to characterize. Phenotypically, chronic rhinosinusitis (CRS) can be classified as either CRS without NP or CRS with NP. CRS without NP, in general, reflects TH1-me...
