A sputum gene expression signature of six biomarkers identifies asthma inflammatory phenotype and steroid responsiveness

This study identifies differentially expression genes in the sputum of people with eosinophilic, neutrophilic and paucigranulocytic asthma. A selection of markers identified using this microarray were further validated using qPCR on a wider sample set.
