In children with hen’s egg allergy at 1 year of age (baseline), they found an increased number of circulating dendritic cells and monocytes that produce more inflammatory cytokines (IL-8 in unstimulated media, and TNF-α, IL-6, IL-1β, IL-8 and IL-10 in LPS-stimulated cells), compared to non-allergic infants (60). This evidence concerns the gene IL1B and egg allergy.
