Research Article: Arthrospira platensis Nanoparticles Mitigate Aging-Related Oxidative Injured Brain Induced by D-galactose in Rats Through Antioxidants, Anti-Inflammatory, and MAPK Pathways

Date Published: 2023-10-02

Abstract:
The increase of reactive oxygen species (ROS) and decreased antioxidant capabilities are two significant contributors to the deterioration that characterizes the aging process. When looking for anti-aging medications, the d-galactose (D-gal)-induced aging model is frequently employed. Proteins and peptides include free amines that can react with D-gal when it build up in the body, producing advanced glycation end products (AGEs). Therefore, AGEs engage with particular receptors (RAGE) in numerous cell types, inducing the activation of the downstream nuclear factor kappa B (NF-?B), leading to ROS formation, which may hasten the aging process. Increased levels of ROS, such as superoxide anion and nitric oxide, cause cellular damage in proteins, lipids, and DNA that can promote the development of various diseases., Antioxidants derived from natural sources are gaining popularity to protect cells from oxidative damage and reduce the production of harmful free radical species. Spirulina is the common name for the fresh blue-green algae Arthrospira platensis, a filamentous cyanobacterium rich in phytochemical components such as essential amino acids and lipids. Carotenoids, other pigments, and riboflavin, a B vitamin, are all present. Aspergillus is a significant contributor of fungal secondary metabolites, which have several biological applications. Anticancer and antioxidant activities are hallmarks of A. awamori supplementation, which also boosts growth efficiency and reduces lipid peroxidation in skeletal muscle., A. awamori contained high levels of several compounds with antioxidant action, including coumarins, glucose, saponins, flavonoids, and tannins. Because of their small size and active surface, nanoparticles are unlike any other active chemical; unlike traditional particles, they can remain in the bloodstream for a longer time, resulting in high and effective activity. This paper investigates the potential intracellular pathway by which A. platensis nanoparticles ameliorate D-gal-induced aging harm in male rats. To assess if NSP has antioxidant capability, we looked at its effects on the oxidative alterations brought on by the D-gal-aging model in the brains of rats.
