RecruitingPhase 1Biological interventionPilot Study to Identify the Mediators and Inflammatory Cell Surface Receptors Involved in Allergic Airway InflammationAsthma is a heterogeneous disorder in which multiple potential inflammatory pathways contribute to airway obstruction. The biological basis for airway inflammation is the subject of intensive investigation. This work is designed to identify airway factors that are responsible for recruiting cells and associate their airway presence with atopy and asthma.
