The topics range from the specific immune-derived maintenance of allergen tolerance and the role of the neuroimmune network in allergic inflammation to conventional atopic diseases and more particular issues of local atopic disorders in the unified airway, oral tolerance, and its breakdown, and its translation in genitourinary aspects of allergic inflammation. Specific chapters are also devoted to allergen-specific immunotherapy (AIT) and anti-allergy treatments. Thought for upper graduate students, it will also be a valued resource for allergy practitioners, pulmonologists, ENT specialists, pediatricians, and translational researchers. Textbook of Allergen Tolerance includes classical didactic features such as abstracts, keywords, background notes, discussion points, and Q&A., as well as 20 audio files Text-to-Speech for the visually impaired, and 10 video to support the readers.
