Interleukin-l2 (IL-12) is a rnonocytelmacrophage-derived cytokine that is critical for T lymphocyte and natural killer cell activities and functions. In this tudy, we examined the regulation of IL-12 expression by human monocytes in response t o bacterial lipopolysaccharide (LPS). Several novel aspects of IL-12 induction from monocytes were shown. Optimal expression of IL-12 rnRNA and bioactivity required specific priming of monocytes by interferon-y (IFN-y) before LPS stimulation. Granulocyte-macrophage colony-stimulating factor (GM-CSF) provided an equivalent priming stimulus for LPS-induced tumor necrosis factor (TNF) and IL-12 p40 mRNA, but primed poorly for LPS-inducible p35 message and secreted IL-12 activity. Macrophage colony-stimulating factor (M-CSF), although a potent survival factor for monocytes, showed no priming activity for IL-12 production. Time course experiments demonstrated independent regulation of p40 and p35 by IFN-)I and LPS. LPS inducibility of p40 expression required only a brief exposure to IFN-y (2 hours),
