Title: Interleukin-13 in asthma pathogenesis. Author: Wills-Karp M. Journal: Immunol Rev; 2004 Dec; 202():175-90. PubMed ID: 15546393. Abstract: Bronchial asthma is a complex disorder that is thought to arise as a result of aberrant T-lymphocyte responses to noninfectious environmental antigens. In particular, the symptoms of asthma are closely associated with the presence of activated T-helper 2 cell (Th2) cytokine-producing cells [interleukin (IL)-4, IL-5, IL-9, and IL-13] in the airway wall. Although each of the Th2 cytokines likely contributes to the overall immune response directed against environmental antigens, a substantial body of evidence points to a singular role for IL-13 in the regulation of the allergic diathesis. Initial studies in animal models of disease provided compelling evidence that IL-13, independently of other Th2 cytokines, was both necessary and sufficient to induce all features of allergic asthma. The importance of IL-13 in allergic disorders in humans is supported by consistent associations between tissue IL-13 levels and genetic variants in the IL-13 gene with asthma and related traits. With the preponderance of evidence continuing to support a pivotal role for IL-13 in allergic disorders, attention is now turned toward understanding the mechanisms by which this cytokine may mediate the pathophysiological features of allergic disease. The emerging paradigm is that IL-13 induces features of the allergic response via a complex array of actions on resident airway cells rather than through traditional effector pathways involving eosinophils and immunoglobulin E-mediated events. In light of these recent developments, this review explores our current understanding of the singular role of IL-13 in the pathogenesis of asthma, with a particular focus on new insights into the mechanisms by which IL-13 mediates various features of asthma.[Abstract] [Full Text] [Related] [New Search]
