Abstract
The expression of intercellular adhesion molecule-1 (ICAM-1) on primary human fibroblasts, a human fibrosarcoma, chondrosarcoma, and adenocarcinoma cell line in response to IL-1, TNF-alpha, or IFN-gamma was studied using an ELISA with anti-ICAM-1 mAb. The induction of ICAM-1 by these cytokines was neutralized by cytokine-specific antisera as well as some steroids and the glycosylation inhibitor, tunicamycin. Cyclohexamide up-regulated the expression of ICAM-1 on chondrosarcoma cells but had little or no effect on carcinoma cells. These data indicate different mechanisms in the regulation and expression of ICAM-1 on the various cell types and provide some insight into the anti-inflammatory effects of some pharmacologic agents.
