Eosinophils as a Treatable Target in COPD

Introduction

The role of eosinophils in airways inflammation has emerged as an important area of study and therapeutics development in respiratory disease over the last 20 years. COPD is a heterogenous condition which is associated with a large burden of illness, high hospitalisation rates and increased mortality. Classically deemed a neutrophilic disease there is increasing evidence that eosinophilic airway inflammation may be present both in stable COPD and during an exacerbation.
