Research Abstract

Using animal models, we evaluated the role of OPN in eosinophilic airway inflammation, allergen sensitization, airway remodeling and emphysema. We have demonstrated that OPN is a novel chamoattractant of eosinophils and is involved in the eosinophilic airway inflammation in asthma. Whereas, OPN inhibited systemic allergen sensitization. The effect of OPN on airway remodeling and emphysema was not observed.
