Experimental design. C57Bl/6j mice were intranasally instilled with silica nanoparticles (5 mg/Kg) or vehicle and 5 h post NPs instillation infected with P.aeruginosa by intranasal instillation. 18 h after infection, inflammatory markers in the lungs were analysed by measuring cytokines and neutrophil recruitment in the broncho-alveolar lavages (BALs). Bacterial loads were studied by bioluminescence after infection with a Pa-luciferase producing strain. Distribution of fluorescently labelled FITC SiO2 NPs (Fate of NPs) was followed by immunofluorescence analysis of cells present in BALs and lung tissues.
