TNF-α release in triple cell co-cultures upon particle incubation. TNF-α levels in the supernatants (upper chamber, lower chamber) were measured by ELISA. TNF-α release in cells exposed to LPS, 1 μm, and 0.078 μm polystyrene particles, TiO2, and gold NP. Values are means ± SD of 3 experiments. * indicates a statistical difference to the levels in the supernatants in the control of the upper chamber, § indicates a statistical difference to the levels in the supernatants in the control of the lower chamber.
