Silver nanoparticles (Ag-NPs) are one of the most popular nanotechnologies because of their unique antibacterial and antifungal properties. Given their increasing use in a wide range of commercial, biomedical and food products, exposure to Ag-NPs is now a reality in people’s lives. However, there is a serious lack of information regarding their potential toxic effects in the central nervous system. In this study, we investigated the biocompatibility of “homemade” Ag-NPs in an in vitro model of human neurons derived from dental pulp mesenchymal stem cells. Our results showed that acute exposure to Ag-NPs cause cytotoxicity, by triggering cell apoptosis, damaging neuronal connections, affecting the mitochondrial activity and changing the mRNA expression level of MT3 and OSGIN2, two genes involved in heavy metals metabolism and cellular growth during oxidative stress conditions. Further studies are needed to …
