IL-12 beta Protein (IL-12 p40; IL-12B), heterodimerizes with the IL-12 p35 subunit (IL-12A) to form IL-12 and with the IL-23 p19 subunit to form IL-23, exerting different regulating functions[1]. IL-12 and IL-23 belong to IL-12 family, are involved in proinflammatory responses and expressed by activated macrophages that serve as an essential inducer of Th1 cells development[2]. IL-12 signals via IL-12RB1 and IL-12RB2 mediated by p-STAT4, whereas IL-23 signals via IL-12RB1 and IL-23R mediated by p-STAT1 and p-STAT3[3]. Interleukin 12 family have been known to be inflammatory factors, induce autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis[4].

    Human HEK293
    IL-35 Protein plays a pivotal role in immune regulation, forming the IL-12 cytokine with IL12B or the IL-35 cytokine with EBI3/IL27B. IL-12 regulates T-cell and natural killer-cell responses, inducing interferon-gamma production. IL-35 contributes significantly to maintaining immune homeostasis in the liver, acting as an immune-suppressive cytokine. Mechanistically, IL-12 exerts effects through the IL12R1 and IL12R2 receptor subunits, phosphorylating cellular substrates and regulating cytokine-responsive genes via phosphorylated STAT4. In the IL-35 context, unconventional receptors composed of IL12RB2 and gp130/IL6ST heterodimers or homodimers mediate signaling, requiring transcription factors STAT1 and STAT4. IL-35 interacts with NBR1, promoting IL-12 secretion, and the IL-35 heterodimer with EBI3/IL27B is non-disulfide-linked, distinguishing it from IL-12.
