Lung biopsies from asthmatics pre- and post- steroid treatment and from healthy control

To better understand the therapeutic potential of targeting Th2 inflammation in asthma, we performed genome-wide expression profiling of endobronchial biopsies in asthmatics and healthy controls stratified according a previously defined three-gene Th2 signature in bronchial epithelium.The Th2 signature is defined as relatively high expression of POSTN, CLCA1, and SERPINB2.
