Interleukin 25 / IL25 / IL17E蛋白背景综述

Interleukin 25 (IL-25), also known as IL17E, is a cytokine that belongs to the IL17 cytokine family and is secreted by type 2 helper T cells (Th2) and mast cells.  IL-25 induces the production of other cytokines, including IL-4, IL-5 and IL-13 in multiple tissues, then induces Th2 immune responses such as blood eosinophilia and increased serum immunoglobulin E levels.This cytokine is an important molecule controlling immunity of the gut and has been implicated in chronic inflammation associated with the gastrointestinal tract. Further, the IL-25 gene has been identified in a chromosomal region associated with autoimmune diseases of the gut such as inflammatory bowel disease (IBD). In addition, studies shown that enforced expression of IL-25 in the lung significantly enhances antigen-induced Th2 cytokine production and eosinophil recruitment into the airways, thus suggesting an important role of IL-25in enhancing allergic airway inflammation by a CD4+ T-cell-dependent mechanism.
