The therapeutic interventions for different phenotypes include IL-17 antagonist (neutrophilic asthma), IL-4/13 antagonist and anti-IgE (allergen-induced asthma), corticosteroids and IL-5 antagonist (idiopathic eosinophilic asthma), and leukotriene antagonist (aspirin exacerbated asthma) [102]. Here, IL4 is linked to asthma.
