Background Differentiation between patients with peanut allergy (PA) and those with peanut
sensitization (PS) who tolerate peanut but have peanut-specific IgE, positive skin prick test
responses, or both represents a significant diagnostic difficulty. Previously, gene expression
microarrays were successfully used to identify biomarkers and explore immune responses
during PA immunotherapy. Objective We aimed to characterize peanut-specific responses
from patients with PA, subjects with PS, and atopic children without peanut allergy (NA …
