Results from a study led by investigators at Massachusetts General Hospital may help to improve the diagnosis and treatment of allergies, pointing to a potential marker of these conditions and a new therapeutic strategy. The research is published in Nature. Nearly one third of the world’s population suffers from allergies. These conditions are caused by certain antibodies—called IgE antibodies—that bind to allergens such as peanuts and trigger a reaction that releases an array of molecules that cause allergic symptoms, and in extreme cases, potentially life-threatening anaphylaxis.
