Summary

IL25 (interleukin 25, HGNC:13765) is a protein-coding gene on chromosome 14q11.2, encoding Interleukin-25 (Q9H293). Cytokine produced by various cells such as eosinophils, T-helper type 2 (Th2) cells or epithelial cells that plays a role in internal safety of adaptive immune responses by regulating cytokine production.

The protein encoded by this gene is a cytokine that shares sequence similarity with interleukin 17. This cytokine can induce NF-kappaB activation, and stimulate the production of interleukin 8. Both this cytokine and interleukin 17B are ligands for the cytokine receptor IL17BR. Studies of a similar gene in mice suggest that this cytokine may be a pro-inflammatory cytokine favoring the Th2-type immune response. Alternative splicing results in multiple transcript variants.

Function. Cytokine produced by various cells such as eosinophils, T-helper type 2 (Th2) cells or epithelial cells that plays a role in internal safety of adaptive immune responses by regulating cytokine production. Promotes and augments T-helper type 2 responses locally or systemically. Exerts its activity via its receptor composed of IL17RA and IL17RB for signal transduction. In turn, stimulates the JAK2-STAT5A pathway and promotes the secretion of type-2 associated cytokines including IL4, IL9 and IL13. Also induces the release of IL8, and IL6 from eosinophils through the combined activation of MAPK and NF-kappa-B pathways. Inhibits the differentiation of T-helper (Th17) cells via the production of IL4, IL5 and IL13.

Subcellular location. Secreted.

Tissue specificity. Expressed at low levels in several tissues, including brain, kidney, lung, prostate, testis, spinal cord, adrenal gland, and trachea.

Similarity. Belongs to the IL-17 family.
