Combined IgE Neutralization and Bifidobacterium longum Supplementation Reduces the Allergic Response in Models of Food Allergy

The authors assessed a fusion protein with extracellular domain of high affinity IgE receptor, FcεRIα, linked to a IgD/IgG4 hybrid Fc domain we term IgETRAP, to reduce the risk of IgG1 Fc-mediated side effects.
