IL-25, which is also known as IL-17E, promotes Th2-biased immune responses. This is in contrast to other IL-17 family members which promote
Th1- and Th17-biased inflammation. IL-25 is an important mediator of allergic reactions and protection against intestinal parasites (1, 2). Mature mouse
IL-25 shares 80% and 91% amino acid sequence identity with human and rat IL-25, respectively (3, 4). During helminth infections and allergic reactions
IL-25 is locally up-regulated in intestinal and airway epithelial cells, atopic dermatitis skin lesions, and local Th2 cells, eosinophils, and basophils (4-9).
It binds to IL-17RB but also requires IL-17 RA to exert its activity (3, 8, 10). IL-25 acts on a variety of cell types which respond with increased production of Th2 cytokines (e.g. IL-4, IL-5, IL-13) and reduced production of Th1 and Th17 cytokines (e.g. IFN- gamma, IL-12, IL-23, IL-17A, IL-17F) (4-6, 8, 9). Airway IL-25 can be activated by MMP-7, a protease that is up-regulated in airway epithelium in response to allergen exposure . Cleaved IL-25 shows
enhanced binding to IL-17 RB and stronger induction of Th2 cytokines . The Th2 cytokines, in turn, trigger expansion of Th2 memory cells and
anti-inflammatory M2 macrophages, increased eosinophil mobilization and activation, and dendritic cell migration (4, 6, 9). These actions promote
protective anti-helminth immune responses (4, 5) as well as allergic inflammation and airway hyperreactivity(11) . The IL-25 induced suppression of Th1 and Th17 cytokines limits Th17 cell expansion and disease pathology in autoimmunity and colitis (12, ).
