Comparison of Expression of Cytokeratin 7 on Epithelium of Nasal Polyps and Mucosa of Chronic Rhinosinusitis
Background and Objective: Nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. Cytokeratins (CK) are intermediate filament proteins that provide mechanical support in epithelial cells. The purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. Mate...
متن کاملExpression of nitric oxide synthase in nasal polyps
Methods NP were obtained after endoscopic surgery for chronic rhinosinusitis, and separated into two categories based on eosinophil density. Nasal middle turbinates (MT) were also collected as normal controls from patients who had undergone surgery for pituitary adenomas. To identify cell types expressing isoforms of NOS, double immunostaining was performed using anti-NOS and anti-leukocyte ant...
متن کاملExpression and distribution of dendritic cells in nasal polyps
The aim of the present study was to investigate the expression, distribution and function of dendritic cells (DCs) and to study their role in nasal polyps. The study involved 55 participants, 45 of whom had nasal polyps and were the study group and 10 who had normal inferior turbinates and were the control group. Immunohistochemical staining was used to visualize the expression and distribution...
متن کاملExpression of basic fibroblast growth factor in nasal polyps.
Basic fibroblast growth factor (bFGF) is a polypeptide that is mitogenic for a wide variety of cell types. We used Northern blot analysis and immunohistochemistry to determine if bFGF is expressed in the nasal polyp tissue; bFGF messenger RNA was detectable in the polyps examined by Northern blot analysis. Strong immunostaining for bFGF was found in blood vessels and along the basement membrane...
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...
