Food allergies are caused by IgE antibodies that are generated by the immune system and bind to allergens such as peanuts, triggering a reaction that in extreme cases can be potentially life-threatening.
New research by scientists at Massachusetts General Hospital (MGH), University of Paris Saclay, and the National Institute of Environmental Health Sciences (NIEHS) reveals why oral immunotherapy, which treats food allergies through incremental increases in consumption of the allergen, can lead to sustained tolerance in some individuals but only transient tolerance in others.
