Background
Human interleukin-12p70 (IL-12p70) activates T cells and natural killer cells that stimulate the production of IFN-γ. It is involved in a number of disorders including periodontitis (1) and chronic toxoplasmosis (2) among others. IL-12p70 is a disulfide-linked heterodimer consisting of IL-12a (p35 subunit) and IL-12b (p40 subunit), mainly produced by macrophages and T lymphocytes and is part of a larger cytokine family that are attractive targets for therapeutic intervention (3,4). The IL-12a subunit also dimerizes with Ebi3 to form IL-35, and the IL-12b subunit dimerizes with IL-23a to form IL-23. IL-12, IL-23, IL-27, and IL-35 are all heterodimeric proteins and members of the IL-12 cytokine family (4).
