"Trojan horse" nanoparticle can halt asthma, allergies

Northwestern University and University of Michigan researchers have adapted a technique, used for treatment of multiple sclerosis and celiac disease, to train the immune system to tolerate allergens. The technique involves wrapping the allergen in a biodegradable polymer that initially hides the allergen from the immune system. The wrapping disappears only during the end-stage of the immune response (debris removal), when reactions do not occur.
