Basophil-derived interleukin-4 promotes epicutaneous antigen sensitization concomitant with the development of food allergy

Exaggerated TSLP production and infiltration of basophils are associated with the pathogenesis of atopic dermatitis (AD), a recognized risk factor for the development of food allergies. While TSLP and basophils have been implicated to promote food-induced allergic disorders in response to epicutaneous sensitization, the mechanisms by which TSLP-elicited basophils guide the progression of allergic inflammation in the skin to distant mucosal sites such as the gastrointestinal tract are poorly understood.
