Immune Tolerance in Allergy & Asthma

Allergen immunotherapy, which helps reduce sensitization by giving gradually increasing doses of an allergen, can improve symptoms for many people but the effects are often not permanent. The Immune Tolerance Network (ITN) is focused on achieving long-lasting tolerance to allergens by investigating treatment approaches that improve on current immunotherapy methods, such as combining immunotherapy with other agents to enhance responses, or exploring new allergen preparations and routes of administration to maximize effectiveness.
