Sputum cell gene expression following allergen challenge. Homo sapiens

Sputum cells collected before (visit 2) and after (visit 4) allergen challenge in asthma patients were isolated and RNA purified for analysis on gene expression arrays. Human subject recruitment part of NIH sponsored protocol as part of the Eosinophil Program Project Grant (PI: Dr. Nizar Jarjour) Overall design: Sputum cell RNA collected from induced sputum cells before and 48 hours after whole-lung allergen challenge.
