Egg-specific IgE and basophil activation but not egg-specific T cells correlate with phenotypes of clinical egg allergy.

Egg-specific antibody and basophil responses, but not T cell responses, are higher in those with reactivity versus tolerance to BE. The egg-specific antibody and T cell responses were highly heterogeneous in this cohort. The clinical implications of this immune heterogeneity will need to be studied longitudinally.
