Scgb1a1-CreTg mice developed signs of asthma pathology that were indistinguishable from their Scgb1a1-CreWT littermates, as judged by histopathological analysis (Fig. S4B), BALF inflammatory cell quantitation (Fig. S4C), TH2 cytokine secretion by MLN cells (Fig. S4E) and serum IgE production (Fig. S4D). This evidence concerns the gene SCGB1A1 and asthma.
