背景
IL-12A,IL12a,InterLeukin-12 subunit aLpha,Cytotoxic Lymphocyte maturation factor 35 kDa subunit (CLMF p35),IL-12 subunit p35,IL12b,IL12B,InterLeukin-12 subunit beta,Cytotoxic Lymphocyte maturation factor 40 kDa subunit,IL-12 subunit p40,Heterodimerizes with Il12B to form the Il-12 cytokine or with EBI3/Il27B to form the Il-35 cytokine. Il-12 is primarily produced by professional antigen-presenting cells (APCs) such as B-cells and dendritic cells (DCs) as well as macrophages and granulocytes and regulates T-cell and natural killer-cell responses,induces the production of interferon-gamma (IFN-gamma),favors the differentiation of T-helper 1 (Th1) cells and is an important link between innate resistance and adaptive immunity. Mechanistically,exerts its biological effects through a receptor composed of Il12R1 and Il12R2 subunits. Binding to the receptor results in the rapid tyrosine phosphorylation of a number of cellular substrates including the JAK family kinases TYK2 and JAK2. In turn,recruited STAT4 gets phosphorylated and translocates to the nucleus where it regulates cytokine/growth factor responsive genes.As part of Il-35,plays essential roles in maintaining the immune homeostasis of the liver microenvironment and functions also as an immune-suppressive cytokine.Mediates biological events through unconventional receptors composed of Il12RB2 and gp130/Il6ST heterodimers or homodimers. Signaling requires the transcription factors STAT1 and STAT4,which form a unique heterodimer that binds to distinct DNA sites.
