warrant deeper insight into the toxicological mechanisms induced by these materials. The
present study was designed to characterize the cell death induced by carbon black (CB) and
titanium dioxide (TiO 2) NPs in bronchial epithelial cells (16HBE14o-cell line and primary
cells) and to investigate the implicated molecular pathways. Results Detailed time course
studies revealed that both CB (13 nm) and TiO 2 (15 nm) NP exposed cells exhibit typical …
