Finally, to ascertain that the deletion of IL4Rα in the eosinophils did not affect their abilities to respond to the chemoattractants, we experimentally induced IL-5/eotaxin-mediated lung eosinophilia in the WT and mye-IL4Rα−/− adult mice (Fig. 6E). The gene discussed is IL4R; the disease is Increased total eosinophil count.
