IL‐5, IL‐8 and GM‐CSF immunostaining of sputum cells in bronchial asthma and chronic bronchitis

Abstract

The immunochemical comparison of GM-CSF and IL-8 localization in sputum cells between bronchial asthma/chronic bronchitis suggests the differential regulation and roles of these cytokines in eosinophilic vs neutrophilic airway inflammation, resulting in the development of different types of airway inflammation.
