Figure 7: Early endosome antigen 1 EEA1 protein expression in THP-1-derived macrophages exposed to summer Milan PM10. The cells were treated with summer PM10 (2.5 μg/cm2) for 30 min, 1 h, 2 h, 4 h, and 6 h and then assessed for EEA1 expression by Western analysis. Mean and s.d. of at least three independent experiments. versus CTRL, versus control, versus CTRL, and versus 30 min.
