Mechanism of action
CCR3 is highly expressed on eosinophils and plays a central role in their migration to sites of inflammation. By antagonizing CCR3, SB213503 reduces eosinophil infiltration into airways and tissues, thereby decreasing eosinophil-mediated inflammation. This mechanism is particularly relevant in eosinophilic airway diseases where eosinophil accumulation drives pathology.
