In addition, it has been demonstrated that Th17 cells and their cytokines such as IL-17A and IL-17F are involved in the pathogenesis of severe asthma. Recently, IL-22, an IL-10 family cytokine that is produced by Th17 cells, has been shown to be expressed at the site of allergic airway inflammation and to inhibit allergic inflammation in mice. In addition to Th17 cells, innate lymphoid cells also produce IL-22 in response to allergen challenge. Functional IL-22 receptor complex is expressed on lung epithelial cells, and IL-22 inhibits cytokine and chemokine production from lung epithelial cells. In this paper, we summarize the recent progress on the roles of IL-22 in the regulation of allergic airway inflammation and discuss its therapeutic potential in asthma.
