Abstract

Several studies suggest that Iron Oxide nanoparticles may arrive to central nervous system independently of the route of administration. Actually, evidences indicate that the presence iron oxide nanoparticles into nervous system are linked to several neurodegenerative diseases. In this regard, our goal was to assess in vitro PolyVinylPirrolidone coated Iron Oxide nanoparticles, diameter of 20 nm, neuro-toxicity and their mechanism of action, which was fixed over the human neuronal cell line SH-SY5Y. Inducted biological effects were evaluated after 4-48 hours at crescents doses 1-100 μg/mL using the following endpoints: (i) Membrane integrity: Nanoparticles have produced no effect over cellular membrane for every dose and time evaluated; (ii) Mitochondrial activity: Starting at 10 μg/mL with a decrease of cellular vitality of 35%, and a maximum decrease of 45% at highest dose (100 μg/mL); (iii) Cellular morphology: Cells have evidenced no alteration after 48 hours of exposure; (iv) Cellular uptake: Dose-time dependent accumulation has observed: blue spots have been found at 10 μg/mL and over. Concluding, mitochondria are apparently the target: considering that the toxic effect produced by PolyVinylPirrolidone coated Iron Oxide nanoparticles after 48 hours of exposure in a dose-time dependent manner was evident.
