Although we did not find significant differences between healthy controls and patients with asthma in terms of concentrations of hNmU-25 in the blood and airways, or levels of NmUR1 expression in type 2 cells, our paired blood and lung specimens from the same donors did reveal higher levels NmU in the airways and higher NmUR1 expression in the lung-derived type 2 T cells. The gene discussed is NMUR1; the disease is asthma.
