Mechanisms and Practical Use of Biologic Therapies for Allergy and Asthma Indications.

This article presents a concise overview of the important aspects of the immunologic mechanisms targeted by T-helper 2-directed monoclonal antibodies, as well as their practical applications in the treatment of allergic disorders (specifically allergic rhinitis) and asthma. Several of these novel agents treat multiple diseases, so understanding their targets and the underlying disease process can aid patient selection. In addition, the particular targets of the therapeutics seem to be shifting to include not only agents that intervene against inflammatory cytokines or their receptors but also specific molecular epitopes and cellular surface proteins.
