Allergy of the respiratory tract

The past year has seen significant advances in several fields of asthma and allergy research. Notable among these advances were the following: the demonstration that inflammatory granulocytes may be a source of cytokines; an increased understanding of the inter-relationships between the inflammatory cells invading the asthmatic bronchial mucosa; some important new approaches to asthma therapy; and the beginnings of a systematic classification of the structure of allergens and their antigenic epitopes.
