Asthma and respiratory diseases

Asthma is a chronic respiratory condition in which the airways become inflamed, narrowed, and hypersensitive, making breathing difficult for hundreds of millions of people worldwide. Researchers studying its physiology examine how immune cells — particularly eosinophils — drive this inflammation, how genetic variation shapes an individual's susceptibility, and why the disease presents so differently across patients, from mild intermittent symptoms to severe, treatment-resistant cases. A central open question is what determines these distinct disease phenotypes and whether targeted therapies, such as biologics that block specific inflammatory signals, can be matched to the right patients based on their underlying immunological profile. Understanding how repeated inflammation gradually remodels airway tissue — and whether that process can be slowed or reversed — remains one of the most active and clinically consequential directions in the field.
