Indirect support for FcεRI also comes from comparisons between our finding on eosinophils in bronchoalveolar lavage (described below) and a study by Zuberi et al. They showed that bronchoalveolar lavage from mice challenged with in vitro formed IgE-complexes had higher levels of IL-4 and more eosinophilia than mice challenged with antigen alone and that the effect was dependent on FcεRI [26]. This evidence concerns the gene IGHE and Increased total eosinophil count.
