Abstract
Intercellular adhesion molecule-1 (ICAM-1) is important in neutrophil-dependent injury. We investigated the effects of monocyte chemoattractant protein-1 (MCP-1) produced by Kupffer cells on ICAM-1 expression after ischemia-reperfusion in rat liver by occluding the portal vein for 30 minutes. Serum concentrations of MCP-1 increased persistently. By Northern analysis, MCP-1 mRNA increased early and persisted. Kupffer cells harvested 6 hours after reperfusion also expressed this transcript. The transcript and protein also were produced by Kupffer cells from naive controls in response to reactive oxygen species. ICAM-1 mRNA transcripts increased, peaked 3 hours after reperfusion, and decreased gradually thereafter. The level of ICAM-1 mRNA transcripts in the WK-5 rat endothelial cell line were markedly enhanced by MCP-1. These results suggest that MCP-1 released by Kupffer cells early after ischemia-reperfusion modulates neutrophil-dependent tissue injury via ICAM-1.Entities:
