The p19 subunit has homology to the p35 subunit of IL-12, as well as to other single chain cytokines such as IL-6 and IL-11. The p40 subunit is homologous to the extracellular domains of the hematopoietic cytokine receptors. Although p19 is expressed by activated macrophages, dendritic cells, T cells, and endothelial cells, only activated macrophages and dendritic cells express p40 concurrently to produce IL-23. IL-23 has biological activities that are similar to, but distinct from IL-12. Both IL-12 and IL-23 induce proliferation and IFN-gamma production by human T cells. While IL-12 acts on both naive and memory human T cells, the effects of IL-23 is restricted to memory T cells. \u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e: Measured by its ability to induce STAT reporter activity in 293F human embryonic kidney cells.
