Interleukin-12 (IL-12) is a receptor for IL-12R and belongs to the type I cytokine receptor family, subfamily 4. This cytokine acts as a growth factor for activated T and NK cells, enhances the lysate activity of natural killer cells or lymphokine-activated killer cells, and stimulates IFN-γ production through resting PBMC. Il-12β (IL-12B) is the main functional chain of IL-12. It can heterodimerize with IL-12 p35 subunit (IL-12A) to form IL-12, or with IL-23 p19 subunit (IL23A) to form IL-23[1]. IL-12 and IL23 belong to the IL-12 family, participate in proinflammatory response, and are expressed by activated macrophages, and play different regulatory functions as necessary inducers of Th1 cell development[2]. More importantly, IL-23 is a heterodimer factor that plays a role in innate and adaptive immunity and may, together with IL-17, constitute the acute response of peripheral tissue to infection. In terms of signal transduction, IL-12 signaling is mediated by p-STAT4, while IL-23 signaling is regulated by IL-23 binding by p-STAT1 and p-STAT3[3]. Moreover, the heterodimer receptor complex composed of IL12RB1 and IL23R further activates the Jak-STAT signaling cascade, stimulates memory rather than naive T cells, and promotes the production of pro-inflammatory cytokines. IL-23 induces autoimmune inflammation, so it may lead to autoimmune inflammatory diseases[4].

    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.
