Interleukin-17E (IL-17E), also known as IL-25, belongs to the IL-17 family of structurally-related cytokines that share a highly conserved C-terminal region, but differ from one another in their N-terminal regions and in their distinct biological roles. It is secreted by type 2 helper T cells and mast cells. IL-17E stimulates secretion of IL-8 and induces activation of the transcription factor NK-κB in cells that express the IL-17BR receptor.1 IL-17E induces the production of other cytokines, including IL-4, IL-5 and IL-13 in multiple tissues. IL-17E is a potent proinflammatory cytokine that plays roles in a number of diseases including rheumatoid arthritis, multiple sclerosis, and promotion of tumor growth.2 In addition, studies have shown that enforced expression of IL-17E in the lung significantly enhances antigen-induced Th2 cytokine production and eosinophil recruitment into the airways. This suggests an important role of IL-17E in enhancing allergic airway inflammation by a CD4+ T-cell-dependent mechanism.3 IL-17E is also an important molecule controlling immunity of the gut and has been implicated in chronic inflammation associated with the gastrointestinal tract.4
