Abstract

Monokines have been increasingly recognized as communication signals that interact with both immune and non-immune cells during inflammation. Specifically, interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha) possess potent effector activities on various cell types. We present novel data demonstrating that human endothelial cells are a major source of a neutrophil chemotactic factor (NCF) synthesized upon stimulation with either IL-1 alpha, IL-1 beta, or TNF-alpha; but not with interleukin-6 (IL-6). Northern blot analysis demonstrated that 20 ng/ml of either IL-1 or TNF-alpha could induce endothelial cells to express significant levels of NCF mRNA, while IL-6 was not active in this system. These data demonstrate that monokines play an important role in mediating acute inflammation via induction of an endothelial cell-derived NCF.
