Oxidative stress generated during aging largely affects erythrocytes. Antioxidative therapies such as polyphenols and flavonoids face limitations like low bioavailability and reduced efficiency. Cerium oxide nanoparticles (CeONPs) can behave as antioxidative enzymes and thus have better efficiency.

Erythrocytes undergo several changes during human aging and age-related diseases and, thus, have been studied as biomarkers of the aging process. The present study aimed to explore the antioxidant ability of metal and metal oxide nanoparticles (NPs) such as iron oxide (Fe3O4), gold (Au), and silver (Ag) to mitigate age-related oxidative stress in human erythrocytes. Metal and metal oxide NPs behave like antioxidative enzymes, directly influencing redox pathways and thus have better efficiency.

Background: Red blood cells (RBCs) are usually considered simple cells and transporters of gases to tissues.

Hypothesis: However, recent research has suggested that RBCs may have diagnostic potential in major neurodegenerative disorders (NDDs).

Results: This review summarizes the current knowledge on changes in RBC in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and other NDDs.

Red blood cells (RBCs) have emerged as biomarkers of the aging process as they undergo several changes in human aging and age-related diseases. The objectives of our study are to explore the effect of human aging on RBC indices, the strengths, therapeutic interventions, challenges, and future directions for using RBCs as a biomarker. Two online databases, PubMed and ScienceDirect, were used to search relevant studies using "RBCs as biomarkers of human aging," "red blood cells [MeSH Terms] AND biomarkers [MeSH Terms] AND human aging [MeSH Terms]," and "erythrocytes and human aging" as keywords.

The telomere length (TL) has increasingly been used as a biomarker of human aging because it has been shown to predict the chances of survival and longevity. Oxidative stress is presumed to be a major cause of telomere shortening, but the importance of oxidative stress as a determinant of telomere shortening remains less clear and has recently been questioned. We analyzed 105 healthy subjects of both sexes between the ages of 20-77 years.

The interaction of nanoparticles with the biological system has increased with the increasing popularity of nanomedicines. Red blood cells (RBCs) are very sensitive, and abundant cells in the blood. They are highly prone to oxidative damage due to constant interaction with oxygen itself, foreign particles in the blood, and the lack of repair mechanism.

Metal oxide nanoparticles are known to exhibit unique properties such as catalyzing the neutralization of superoxide anions, hydroxyl radicals, hydrogen peroxides and behave as antioxidant enzymes. Oxidative stress, damage and chronic inflammation are major causes and consequences of aging and age-associated disorders. With the increasing popularity of metal oxide nanoparticles, they have been applied in various age-related pathologies using their antioxidant property.
