The goal of the present study focused on the adverse reaction of contrast medium (CM) via the induction of inflammatory molecules in human umbilical vein endothelial cells (HUVECs). Ultravist-induced monocyte chemoattractant protein-1 (MCP-1) and vascular cell adhesion molecule-1 (VCAM-1) gene expression was markedly increased in interleukin-4 (IL-4)-pretreated HUVECs in a time- and dose-dependent manner and was paralleled by concomitant production of MCP-1 and VCAM-1 proteins. MCP-1 and VCAM-1 gene expression by Ultravist in combination with IL-4 was mediated by the c-Jun N-terminal kinases (JNK1/2) signaling pathway. IL-4-pretreated Ultravist-stimulated HUVECs showed greatly increased migration and adhesion of THP-1 cells. Cell migration was decreased by treatment of CCR2 antagonist, and cell adhesion was also decreased by VCAM-1 blocking antibody. Furthermore, when tested in vivo under similar conditions, MCP-1 protein was significantly increased in Ultravist combined with IL-4-injected mice. Taken together, our findings suggest that MCP-1 blocking may be crucial in preventing the endothelial dysfunction induced by contrast medium in patients with inflammatory disease and atherosclerosis.
