Increased gene expression of inflammatory markers in nasal turbinate of patients with persistent allergic rhinitis and chronic obstruction

The pathogenesis of persistent allergic rhinitis with chronic and refractory nasal obstruction is still unknown. Inflammation and tissue remodeling are known to play a role, but this has not been studied thoroughly. The purpose of this study is to identify the profile of gene expression of inflammatory and remodeling markers in nasal mucosa of patients with PAR and chronic obstruction. After informed consent, we obtained nasal mucosa tissue from...
