Chimerigen
IL-35 (mouse):Fc (human) (rec.)
Method: 5x10^4 Raw 264.7 cells are treated with IL-35 (mouse):Fc (human) (rec.) (Prod. No. CHI-MF-11135) or a control, Fc (human) IgG1 Control (rec.) (Prod. No. AG-35B-0007) for 16 hours at different concentrations as indicated on the figure. Then LPS (1µg/ml; Prod. No. IAX-100-008-C500) is added for another 24 hours. Supernatants are collected and mouse IL-6 is measured using an IL-6 (mouse) ELISA Kit. OD 450nm values indicating presence of mouse IL-6 are shown.

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. 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. Recently, insufficient IL-35 levels were shown to play a pivotal role in the development of type 1 diabetes (T1D) and autoimmune diseases.
