Airway mucus plug is a common phe-notype in asthma that increases the risk of acute asthma attacks by causing aggravation of airflow obstruction.Given its important role in asthma,treatment targeting airway mucus plugs may be a strategy to control asthma progression and prevent fatal asthma exacerbations.Previous studies have shown that acidosophils and T2 type inflammation are related with the formation of mucus plugs,and bio-targeted drugs targeting the above pathways may be effective in the treatment of airway mucus plugs.
