Currently, it is found to play an important role in promoting airway inflammation. Chronic rhinosinusitis is a chronic inflammatory disease of the nasal cavity and sinus mucosa. Under the stimulation of a variety of factors, the secretion of IL-8 in the nasal mucosa and nasal polyps of CRS patients could increase. Therefore, it can cause inflammation and mucosal damage by trending chemotaxis neutrophils and eosinophils.
