On page 5, the authors state that CeO2 NPs downregulated the expression of genes including ITGB2, TLR6, HLA-DRB3, TIRAP, and HLA-A in the context of a plant study (citing Verstraeten et al., 2014). These are human immune genes (e.g., HLA are human leukocyte antigens) and are not present in plants. This serious biological inaccuracy suggests a major error in data interpretation or citation, compromising the scientific validity of this section.
