Background Cutaneous exposure to food allergens predisposes to food allergy, which is
commonly associated with atopic dermatitis (AD). Levels of the epithelial cytokine IL-33 are
increased in skin lesions and serum of patients with AD. Mast cells (MCs) play a critical role
in food-induced anaphylaxis and express the IL-33 receptor ST2. The role of IL-33 in
patients with MC-dependent food anaphylaxis is unknown. Objective We sought to
determine the role and mechanism of action of IL-33 in patients with food-induced …
