What is The Latest Treatment for Nasal Polyps ? ( Study )
The presenting symptoms of nasal disorders such as allergic rhinitis, chronic rhinosinusitis with nasal polyps, and aspirin-induced asthma include nasal discharge and nasal congestion, which are responsible for not only decreasing quality of life, but also impeding the activities of daily living. These pathological conditions, which lead to mucus overproduction and edema in the nasal mucosa, might be precipitated by the actions of molecules such as pendrin and pe- riostin. Periostin is an extracellular matrix protein originally isolated from an osteoblast cell line; its production is induced by IL-4 and IL-13 in airway epithelial cells.Periostin is also a regulator of fibrosis and collagen deposition, and although it has been recognized for its important role in myocardial repair and remodeling following myocardial infarction,2 its over-production in the nasal mucosa has been reported to contribute to polyp formation. Although we know that pendrin is genetically associated w...
