A composition of ceria oxide nanoparticles and their biological applications for the protection of mammalian cells against reactive oxygen species, with additional specifications for the treatment of retinal neurons against light-induced degeneration.
Light-induced retina degeneration and age-related macular degeneration (AMD) are two common medical conditions which lead to sight distortion and blindness. These conditions are often caused by harmful compounds known as reactive oxygen species (ROS). ROS are often generated as a byproduct of various cellular processes and/or during the retinas exposure to UV radiation. ROS are extremely aggressive compounds which attack their surrounding tissue, causing irreversible damage over time. Currently no satisfactory remedies to prevent the eventual outcome of blindness from these ROS exist, until now.
Cerium oxide nanoparticles show great potential to treat retinal degenerative conditions since studies have shown they protect neurons from apoptosis induced by hydrogen peroxide (an extremely harmful ROS) in tests on the cellular (in vitro) and whole organism (in vivo) levels. By breaking down these ROS, cerium oxide nanoparticles effectively extend the longevity of neurons and any other cells within the body which are plagued by the accumulation of these harmful chemical species.
