Updated and substantially enlarged from the 1991 Allergen Immunotherapy to incorporate the many new therapies to treat allergic and immunological disease, many developed by applying the methods of molecular biology. Presents the basic principles of immunotherapy with allergens as perhaps the best chance for producing someday a specific cure for allergic illness. Describes in detail the various allergen groups, such as trees, grasses, weeds, molds, Hymenoptera and other insect allergens, mammalian allergens, latex, drugs, and foods. Defines the biochemical and molecular characteristics by which allergens are manufactured and standardized for optimal use in diagnosis and immunotherapy, including many that have now been cloned and expressed as homogeneous recombinant antigens and proteins. Also presents the scientific data on immunotherapeutic procedures to treat various allergic diseases and how such therapy modifies the immunological process responsible for IgE-mediated disease.
