The levels of serum IgE were significantly correlated with subepithelial EG2+ eosinophils in normal subjects at day 4 (r = 0.64, P = .017) and in subjects with asthma at both baseline (r = 0.94, P = .005) and day 4 (r = 0.83, P = .013) (Figs 7A, 7B). The gene discussed is IGHE; the disease is asthma.
