  • Title: [IgE and respiratory disease].
    Author: Girodet PO, Casset A, Magnan A, de Blay F, Chanez P, Tunon De Lara JM.
    Journal: Rev Mal Respir; 2005 Dec; 22(6 Pt 1):967-81. PubMed ID: 16249755.
    Abstract:
    INTRODUCTION: IgE is known to provide the biological basis for allergy and immediate hypersensitivity. However, recent data provide some evidence that IgE responses are involved in other inflammatory processes apart from allergy, including several respiratory diseases. STATE OF THE ART: IgE binds to mast cells and basophils but also to other inflammatory cells, which are involved in non-allergic processes. IgE has a role in antigen presentation and is implicated in a number of other immune mechanisms. In the airways, IgE plays an important role in bronchial hyperactivity, even in the absence of an allergen. Epidemiological studies have demonstrated that IgE response is related not only to allergy but also to asthma symptoms, in the presence or absence of atopy, as well as exposure to cigarette smoke. IgE response is altered in several respiratory diseases including extrinsic and intrinsic asthma and allergic bronchopulmonary aspergillosis. CONCLUSION AND PERSPECTIVES: Since anti-IgE monoclonal antibodies are now available for administration to humans, a better understanding of the IgE response may allow the identification of novel therapeutic targets in the field of respiratory disease.
