| Summary: | Asthma pathogenesis is complex and involves the interplay of many factors and actions. Airway inflammation in allergic asthma is characterized by an exaggerated activation of T helper type 2 cells, IgE production and infiltration and activation of eosinophils. The results of studies conducted in recent years indicate that the deficit of naturally occurring Foxp3+CD25+CD4+ and Foxp3+CD25+CD8+ regulatory T cells and type 1 regulatory T cells plays a pivotal role in the development of this disease. Moreover, numerous studies have provided convincing evidence that a decrease in IL-10 production and an increase in IL-17 production have an important place in the pathophysiology of asthma. TGF-β is another important cytokine involved in this disease. TGF-β has a paradoxical status in relation to asthma pathogenesis because it seems to play a role in both suppressing and promoting asthma development. This review discusses briefly clinical and experimental data concerning the involvement of T regulatory cells and IL-10, IL-17 and TGF-β in the pathogenesis of asthma.
