title: [The role of immunoregulatory disorders in pathogenesis of bronchial asthma].
abstract: The set of cellular and humoral elements which participate in the pathogenetic chain of bronchial asthma is regarded as characteristic for this disease. They include, among many others: mast cells, basophils, eosinophils, macrophages, Th2 phenotype lymphocytes, IgE antibodies, histamine, leukotrienes and some pro-inflammatory cytokines. The majority of them are effectory agents active at the end of pathogenic immune response. The therapy antagonizing their influences alleviates the symptoms but does not eliminate the cause of the illness. The authors call the attention to the pathogenic significance of immunoregulatory disorders which appear during the induction phase of immune response in patients with symptoms of bronchial asthma. On the basis of current literature and own, already published studies, the authors point to the significance of recently discovered and described thymus-dependent cellular population of regulatory T lymphocytes which are active in prevention of development of allergic and autoaggressive reactions. It is suggested that deficiency of regulatory T cell population caused by undesired environmental influence on thymic lymphopoiesis and the concomitant overstimulation of immunogenic antigen-presenting dendritic cells, create the conditions under which pathogenic immune response may well develop. Therefore, the possibility of introducing of prothymic immunocorrective treatment in bronchial asthma should be taken into account in further clinical studies.
