Oxidative stress plays a critical role in the pathogenesis of upper and lower respiratory tract diseases, such as chronic rhinosinusitis with nasal polyps (CRSwNP), allergic rhinitis (AR), and asthma (AS). In the current study, researchers from Huazhong University of Science and Technology and affiliated organizations aimed to assess the role of the essential antioxidant enzyme, heme oxygenase 1 (HMOX1), in these airway diseases.
