Immunoglobulin E-binding epitopes of mite allergens: from characterization to immunotherapy.
House dust mites and storage mites produce a number of allergens that can induce hypersensitivity reactions in humans and result in allergic diseases like asthma, rhinitis, and dermatitis. Recent advances in identifying and characterizing these allergens--and, in particular, their immunoglobulin E (IgE)-binding epitopes--have produced a wealth of knowledge. Here, methods for identifying IgE-binding epitopes, from immunoassays to in silico approaches, are summarized and placed in context with the identification of epitopes of mite allergens, particularly from the Dermatophagoides spp. major allergen groups 1 and 2. Finally, the transfer of this information to the clinical development and application of new diagnostic and immunotherapeutic approaches is discussed. While progress in recent years has built on the specific immunotherapies established decades ago, much work remains to be done to mitigate mite allergic disease. Future studies should seek to identify epitopes for mite species beyond Dermatophagoides and for minor allergens. Efforts in translational medicine should use the current epitope data to develop modified allergens for immunotherapy.
