In Vivo Inflammatory Effects of Ceria Nanoparticles on CD‐1 Mouse: Evaluation by Hematological, Histological, and TEM Analysis

Journal of Immunology Research, Volume 2014, Issue 1, 2014., 2014
The attention on CeO2‐NPs environmental and in vivo effects is due to their presence in diesel exhaust and in diesel filters that release a more water‐soluble form of ceria NPs, as well as to their use for medical applications. In this work, acute and subacute in vivo toxicity assays demonstrate no lethal effect of these NPs. Anyhow, performing in vivo
