[Recent findings in the pathogenesis of bronchial asthma].

The latest discoveries about the pathogenesis of asthma are reported with emphasis on new data concerning the discovery of factors capable of controlling the production of IgE antibodies. The mechanisms implicated in early and late phase reactions are then discussed. In addition, the relationships between neuropeptides and chronic inflammation are described. Finally, the role of active substances produced by the bronchial epithelium on the induction and maintenance of bronchial inflammation is reviewed.
