Cytokine-endothelial interactions in inflammation, immunity, and vascular injury.
This paper reviews the evidence that cytokines induce a variety of functional and structural alterations in endothelium and that cytokine-endothelial interactions play important roles in the evolution of inflammatory and immune responses. The effect of cytokines, particularly interleukin-1 and tumor necrosis factor, on leukocyte-endothelial adhesion has led to the discovery of several endothelial adhesion molecules, and the molecular and biological characteristics of these are described. Finally, the review discusses the possible contribution of cytokine-induced activation to vascular injury in such pathological processes as septic shock, the Shwartzman reaction, delayed hypersensitivity, and immune-mediated vasculitis.
