In vivo and in vitro models of food allergyIgE - the main player of food allergy

Food allergy is a growing problem worldwide, presently affecting 2-4% of adults and 5-8% of young children. IgE is a key player in food allergy. Consequently huge efforts have been made to develop tests to detect either the presence of IgE molecules, their allergen binding sites or their functionality, in order to provide information regarding the patient's food allergy. The ultimate goal is to develop tools that are capable of discriminating between asymptomatic sensitization and a clinically relevant food allergy, and between different allergic phenotypes in an accurate and trustworthy manner. This may generate better diagnostic, prognostic and therapeutic monitoring tools for the future.
