MCP-1 levels in the supernatant of HUVECS (A) and HUAECs (B). Cells were incubated with 1 mg of unloaded, LTB₄-loaded MS or LTB₄ in solution (200 ng/ml). MCP-1 content was determined by ELISA. Results are expressed as mean ± SEM (n = 3); **P < 0.01, ***P < 0.001, LTB₄-loaded MS compared to control (medium). ###P < 0.001 and &&&P < 0.001, LTB₄-loaded MS compared to unloaded MS and LTB₄ solution, respectively.
