dc.description.abstractIgE is central to the development of allergic diseases, and its neutralization alleviates allergic symptoms. However, most of these antibodies are based on IgG1, which is associated with an increased risk of fragment crystallizable-mediated side effects. Moreover, omalizumab, an anti-IgE antibody approved for therapeutic use, has limited benefits for patients with high IgE levels. Here, we assess a fusion protein with extracellular domain of high affinity IgE receptor, FcepsilonRIalpha, linked to a IgD/IgG4 hybrid Fc domain we term IgE(TRAP,) to reduce the risk of IgG1 Fc-mediated side effects. IgE(TRAP) shows enhanced IgE binding affinity compared to omalizumab. We also see an enhanced therapeutic effect of IgE(TRAP) in food allergy models when combined with Bifidobacterium longum, which results in mast cell number and free IgE levels. The combination of IgE(TRAP) and B. longum may therefore represent a potent treatment for allergic patients with high IgE levels.-
