Cerium oxide nanoparticles: a 'radical' approach to neurodegenerative disease treatment

Nanomedicine (Lond). 2017 Mar;12(5):545-553. doi: 10.2217/nnm-2016-0399. Epub 2017 Feb 9.

Abstract

Despite advances in understanding the factors that cause many neurodegenerative diseases (NDs), no current therapies have yielded significant results. Cerium oxide nanoparticles (CeONPs) have recently emerged as therapeutics for the treatment of NDs due to their antioxidant properties. This report summarizes the recent findings regarding CeONPs in treatment of various NDs, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, ischemic stroke and amyotrophic lateral sclerosis. Interest in CeONPs as a potential nanomedicine for NDs has increased due to: their ability to alter signaling pathways, small diameter allowing passage through the blood-brain barrier and scavenging of reactive oxygen species. Due to these properties, CeONPs could eventually revolutionize existing treatments for NDs.

Keywords: antioxidant; cerium oxide nanoparticles; neurodegenerative diseases; oxidative stress.
