Human cytokine array was used to investigate the cytokine profile of U937 and KERTr after exposure to indoor dust or dust extracts. The release of MCP-1 was increased while release of IL-8 and IL-1β on U937 were decreased after exposure to indoor dust. The releases of RANTES, IL-8 and VEGF from KERTr after exposure to dust extract were increased. The results of IL-8 ELISA assay were consistent with the cytokine array. Real-time RT-PCR was performed to analyze relative changes in gene expression. The MCP-1 mRNA levels were increased after U937 exposure to 18 indoor dust samples, whereas, IL-8 and IL-1β mRNA level showed both up-regulation and down-regulation. The dose-related increase and decrease response was observed on MCP-1 and IL-8, respectively. Most indoor dust extracts increased RANTES, IL-8 and VEGF mRNA levels on KERTr. The dose-dependent response was observed on RANTES and IL-8. A significant correlation (r= 0.48, p< 0.05) was obtained between the total PAHs concentration in dust extracts and the induction of RANTES mRNA. Copyright © 2010 Elsevier Ireland Ltd.
