Effect of CuO NP treatment on murine lung inflammation. HE staining of the lung tissues harvested after 2.5, 5, and 10 mg/kg CuO NP treatment for 14 days in contrast to the saline control (a). qRT-PCR analysis of the major proinflammatory genes in the lung tissues after treatment with 5 mg/kg CuO NPs for 14 days (b). TGF-β levels in the BALF were measured using the ELISA kit. Representatives of at least 3 independent experiments are shown.
