Abstract
Cerium oxide nanoparticles (CeONP) can be used to treat or prevent neurodegenerative diseases, including for example Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, AIDS-related dementia, ALS, progressive supranuclear palsy, and encephalitis, as well as mitochondrial diseases and diseases associated with mitochondrial damage. In particular, CeONP having an average size of about 2 nm to about 100 nm can be administered in an amount sufficient to block production of hydroxyl or superoxide radicals, block free radical production by Aβ(1-42), block Aβ(1-42)-induced neuronal death, block Aβ(1-42)-induced [Ca2+]i dysfunction in neurons, block Aβ(1-42)-induced lipid peroxidation, decrease loss of dopaminergic neurotransmission, or reduce mitochondrial dysfunction in a cell. CeONP can also be effective in treating conditions involving toxic exposures to compounds that induce mitochondrial dysfunction, such as rotenone, cyanide, carbon monoxide, polychlorinated biphenyls (PCBs) and other mitochondrial toxins.
