Expression of MCP-1 and LFA-1 in THP-1 monocytes and ICAM-1 in HAECs. a MCP-1 and b LFA-1 relative mRNA expression levels in THP-1 cells were determined 6 h after exposure to 0.1 or 10 μg/ml of SWCNTs or DWCNTs. Data are mean ± SD. (n = 8,*p < 0.05 vs. control; CTL) c Representative images of western blot analysis of ICAM-1 in HAECs exposed to 0.1 or 10 μg/ml of SWCNTs or DWCNTs. d Relative expression levels of ICAM-1 in HAECs exposed to SWCNTs or DWCNTs. Data are mean ± SD. (n = 6,*p < 0.05 vs. control; CTL) MCP-1: monocyte chemotactic protein-1, LFA-1: lymphocyte function-associated antigen 1, ICAM-1: intracellular adhesion molecule 1, SWCNT: single-walled carbon nanotube, DWCNT: double-walled carbon nanotube
