Type 2 Inflammation in Eosinophilic Chronic Obstructive Pulmonary Disease

Type 2 (T2) inflammation in asthma encompasses the presence of eosinophilic inflammation and / or selected cytokines including interleukin (IL)-13. Some chronic obstructive pulmonary disease (COPD) patients have increased airway eosinophil numbers, which is associated with greater effects of inhaled corticosteroids (ICS). Studies of T2 inflammation in COPD have used hypothesis free, open platform approaches.
