摘要：

The interactions of interleukin-1-beta (IL-1-beta) and basic fibroblast growth factor (bFGF) with monolayer cultures of rabbit articular chondrocytes were examined. Both agonists resulted in a synergistic increase in prostanoid production, to levels higher than the maximal level for either protein alone. The synergy was time- and dose-dependent, was augmented in serum-free medium, and was blocked by indomethacin or a polyclonal antibody to IL-1-beta. The proteins had opposite effects on cell growth, and IL-1-beta completely blocked the mitogenic effect of bFGF. Pretreatment of cells with IL-1-beta induced a down-regulation in the number of the bFGF high-affinity receptors. Pretreatment of cells with bFGF increased the number of IL-1 receptors, which was dependent on messenger RNA synthesis.
