Abstract
- Summary: Interleukin‐35 (IL‐35) is a recently identified heterodimeric cytokine in the IL‐12 family. It consists of an IL‐12 subunit α chain (P35) and IL‐27 subunit Epstein–Barr virus‐induced gene 3 (EBI3) β chain. Unlike the other IL‐12 family members, it signals through four unconventional receptors: IL‐12Rβ2–IL‐27Rα, IL‐12Rβ2–IL‐12Rβ2, IL‐12Rβ2–GP130, and GP130–GP130. Interleukin‐35 signaling is mainly carried out through the signal transducer and activator of transcription family of proteins. It is secreted not only by regulatory T (Treg) cells, but also by CD8+ Treg cells, activated dendritic cells and regulatory B cells. It exhibits immunosuppressive functions distinct from those of other members of the IL‐12 family; these are mediated primarily by the inhibition of T helper type 17 cell differentiation and promotion of Treg cell proliferation. Interleukin‐35 plays a critical role in several immune‐associated diseases, such as autoimmune diseases and viral and bacterial infections, as well as in tumors. In this review, we summarize the structure and function of IL‐35, describe its role in immune‐related disorders, and discuss the mechanisms by which it regulates the development and progression of diseases, including inflammatory bowel disease, collagen‐induced arthritis, allergic airway disease, hepatitis, and tumors. The recent research on IL‐35, combined with improved techniques of studying receptors and signal transduction pathways, allows for consideration of IL‐35 as a novel immunotherapy target.
