Interleukin 2 (IL-2) is an essential mediator of the immune response and has also been shown to be protective in experimental models of sepsis. Macrophages have IL-2 receptors but their function is unknown. We investigated the effect of IL-2 on Kupffer cells, the fixed macrophages of the liver, using an in vitro rat hepatocyte-Kupffer cell coculture system. In this model, endotoxin (lipopolysaccharide) triggers Kupffer cells to induce suppression of hepatocyte protein synthesis. We found that pretreatment with 10 U/mL or more of IL-2 primed Kupffer cells, significantly reducing the concentration of lipopolysaccharide necessary to trigger Kupffer cell-mediated suppression of hepatocyte protein synthesis. Higher concentrations of IL-2 (greater than or equal to 1 x 10(4) U/mL) alone were capable of priming and triggering Kupffer cells to suppress hepatocyte protein synthesis. These data show that IL-2 increases Kupffer cell sensitivity to endotoxin, suggesting that IL-2 may play an important role in regulating macrophage responses to septic stimuli.
