Abstract
Food allergy is an important cause of life-threatening hypersensitivity reactions. Avoidance of allergenic foods is the only method of prevention that currently is available for sensitized patients. This method of prevention is difficult and often impossible. With better characterization of allergens and better understanding of the immunologic mechanism, investigators have developed several therapeutic modalities that potentially are applicable to the treatment and prevention of food allergy. Therapeutic options currently under investigation include peptide immunotherapy, DNA immunization, immunization with immunostimulatory sequences, anti-IgE therapy, and genetic modification of foods. These exciting developments hold promise for the safe and effective treatment and prevention of food allergy in the next several years.
