Induction of IL -8 and MCP- 1 in A549 cells exposed to Ag ENMs 50, 80 and 200 nm. Cells were treated with 6 concentrations (μg/cm2) of Ag ENMs for 24 h. The data are expressed as mean ± SD of at least three independent experiments. *statistically significant (p < 0.05) difference from the unexposed control. Horizontal line represents expressed level of IL8 (81.8 ± 31.5 pg/ml) and MCP-1 (143.3 ± 26.68 pg/ml) in untreated cells. TNFα (20 ng/ml) as a positive control (IL-8) gave 386.5 ± 87.92 pg/ml and (MCP-1) gave 528.3 ± 134.52 pg/ml.
