Summary

This study was designed to compare certain immune cells (called ILC2) in the lungs of children with severe asthma versus children without asthma. The goal was to see if these cells are higher in asthmatic children and if they relate to other markers of airway inflammation. However, the study was withdrawn before any participants were enrolled, so no results are available.
