• doses, on toxicological responses of rat lungs determined in broncho-alveolar lavage fluids by using the same endpoints as in the ex vivo studies described above [22]. Remarkably, the rather consistent findings of increased pro-inflammatory response in an AgNP dose-dependent manner as determined by

• , mitochondrial changes did not change in between any of the groups of rats. Interestingly, the inflammatory response determined by TNF-α and IL-8 release increased significantly depending on the LPS dose in PCLS of rats that were exposed to suspensions containing 250 µg AgNP (Figure 8). It is quite striking that

The cell-type specific uptake of polymer-coated or micelle-embedded QDs and SPIOs does not provoke an acute pro-inflammatory response in the liver

• [27][28] can induce a tolerance to internalized gut-derived substances and usually does not support pro-inflammatory T cell effector responses [28][29][30]. Thus, it is quite unlikely that nanocrystals internalized by LSEC provoke an acute pro-inflammatory response. In order to test this hypothesis

• highest concentrations under submerged conditions promoted a cytotoxic and pro-inflammatory response after 24 h. Interestingly, when cell cultures were co-incubated with lipopolysaccharide (LPS), no synergistic inflammatory effects were observed. By using two different exposure scenarios it has been shown

• (data not shown). Cytokine/chemokine secretion As described in [44], the release of the pro-inflammatory markers TNF-α and IL-8 was measured 4 and 24 h after exposure by enzyme linked immunosorbent assay (ELISA) to characterize the pro-inflammatory response of the cell culture lung model (Figure 5
