We studied the effects of the immune mediators interleukin 1, interleukin 2, tumor necrosis factor, immune interferon, and lipopolysaccharide on the expression of the endothelial activation antigen recognized by the murine monoclonal antibody H4/18 in short term organ cultures of newborn foreskins. No endothelial staining was detectable before culture. Interleukin 1, tumor necrosis factor, and lipopolysaccharide each induced 2+ to 3+ H4/18 staining of microvascular endothelium at 6 hr. Combining mediators produced additive (3+ to 4+) effects, and reactivity was lost or markedly diminished by 24 hr. Incubation with culture medium alone resulted in 1+ to 2+ H4/18 staining at 6 hr, and medium conditioned by cultured foreskins, but not mock-conditioned medium, could induce H4/18 binding in cultured human umbilical vein endothelial cells. The spontaneous expression of microvascular staining in the foreskins was markedly inhibited by cyclosporin A, but not polymyxin B sulfate or dexamethasone; cyclosporin A did not inhibit induction of staining by exogenous mediators. Both light level and immunoultrastructural studies demonstrated H4/18 expression to be associated predominantly with postcapillary venular endothelial cells of the superficial vascular plexus. We conclude that microvascular endothelium of skin can undergo activation in response to exogenous and endogenous cytokines, with the greatest changes occurring in those portions of the vessels most involved in leukocyte and lymphocyte trafficking.
