The textbook "Allergy and Allergic Diseases" offers a comprehensive and up-to-date compilation on one of the most exciting research areas in medicine: allergic diseases. It particularly highlights the connections between allergies and their effects on the skin, respiratory system, and digestive tract. Given the dramatic increase in allergic disorders worldwide and the ongoing development of clinical immunology and allergology, the necessity to link basic and clinical sciences in this field becomes evident. The book is divided into fundamental and clinical sections and places special emphasis on the various components of the immune and inflammatory response that contribute to the development of allergic diseases. The topics range from molecular biology to clinical symptoms and are designed to appeal to a broad audience, including professionals in clinical immunology, scientists, internists, and educators.
