From: Exposure to TiO2 nanoparticles increases Staphylococcus aureus infection of HeLa cells
TEM cross sections of J77A4.1 control cells (a, d); cells exposed to 0.1Â mg/ml anatase (b, e), and to 0.1Â mg/ml rutile TiO2 (c, f) followed by exposure to S. aureus bacteria for 90Â min. Arrows point to bacteria. g Number of ingested S. aureus bacteria per J77A4.1 macrophage cell exposed to anatase, rutile and unexposed to TiO2 nanoparticles. h Extracellular LDH levels in J77A4.1 cells exposed to TiO2 NPs and control unexposed cells. *Means PÂ <Â 0.05
