General description
Research area: IMMUNO AND CKS. Interleukin-35 (IL-35) is a novel IL-12 family cytokine produced by regulatory T cells (Treg) but not by resting or activated effector T cells (Teff). IL-35 is a heterodimeric protein composed of EBI3 (Epstein-Barr-Virus-induced gene 3) and IL-12a (p35). EBI3 is a downstream target of Foxp3, a transcription factor required for Treg-cell development and function, and thus Treg-cell restriction of IL35 occurs.
Application
IL-35 has been used to study its immunosuppressive effect on acute graft-versus-host disease in a mouse model.Ithas also been used to study its effects on the differentiation of granulocytemacrophage-colony-stimulating factor-producing T helper cells (ThGM). IL-35has been used to study its effects on bleomycin-induced pulmonary fibrosis.
Biochem/physiol Actions
Regulatory T cells are essential for maintaining self tolerance and preventing autoimmunity, and IL-35 is identified as a molecule that mediates the immune suppression function of Treg-cell. As an inhibitory cytokine, IL-35 induces proliferation of Treg-cell populations but suppresses Th17 cell development. Studies in mice show the absence of either IL-35 chain from Treg-cell reduces the cells′ ability to suppress inflammation using an experimental model for inflammatory bowel disease. IL-35 is suggested as a potential target of immunotherapy.IL-35 is produced inresponse to agonists of toll-like receptors 3 and 4 (TLR 3 & 4) and interferon γ (IFN-γ). It is secreted mainly by activated B cells, CD4+ Foxp3+ regulatoryT cells (Tregs), and at a lower concentration by monocytes, smooth muscle cells, and endothelial cells.
Physical form
Lyophilized from 0.2 μm-filtered solution in PBS.
Reconstitution
Reconstitute at 100 μg/mL in sterile PBS.
Other Notes
The mouse IL-35 complex composed of the Ebi3 subunit (aa 23-228) and the IL-12a (p35) subunit (aa 23-215) is fused through a polypeptide linker to the Fc region of human IgG1.

The immune system contributes to the pathophysiology of endometriosis. The role of ThGM cells, which produce granulocyte macrophage-colony-stimulating factor (GM-CSF), in the pathogenesis of endometriosis remains unknown. To analyze the features of ThGM cells in endometriosis, a mouse endometriosis model
