IgE promotes type 2 innate lymphoid cells in murine food allergy

Background Mast cells serve an important sentinel function at mucosal barriers and have been implicated as key early inducers of Type 2 immune responses in food allergy. The generation of Th2 and IgE following food allergen ingestion is inhibited in the absence of mast cells. Group 2 innate lymphoid cells are also thought to play an important early role in nascent allergic responses.
