Exposure to CeO2 NP induces autophagy. Representative lung tissue sections of GFP-LC3 mice exposed to Saline or CeO2 NP after 1 day (Panel a), 7 days (Panel b) or 28 days (Panel c). Original magnification × 200. Panel d: representative lung tissue sections of C57Bl/6 mice exposed to Saline or 50 μg CeO2 NP and stained, after 28 days, for Atg5. Original magnification × 200
