Effect of CuO/Silica and MCP ultrafine particles on cytokine release from BEAS-2B at 4 h post-exposure. Since IL-2, IL-12p40, IL12p70, IL-18, IFNγ, TNFα, IFNα2 were not detected at 4 h after ultrafine particle exposure, they were excluded from the figure. Results are expressed as mean ± SEM (n = 3). Significantly different from ^auntreated controls, ^bbetween CuO/Silica and MCP230 groups.
