Therefore, we wanted to correlate the expression of the IL3R alpha chain in untreated PBMCs and the clinical parameter of the asthmatic preschoolers and found a significant induction of IL-3R alpha chain/HPRT mRNA expression in asthmatic children with controlled asthma as well as in those treated with non-steroid medications (Figures 1H, I). This evidence concerns the gene IL3RA and asthma.
