In recent years, growing awareness of the role oxidative stress in brain health has prompted antioxidants, especially dietary to receive attention as possible treatments strategies for patients with neurodegenerative diseases (NDs). The most widely studied antioxidants include active substances such vitamins, carotenoids, flavonoids and polyphenols. Dietary are found usually consumed foods fresh fruits, vegetables, nuts oils gaining popularity due recently their potential preventive protective agents against NDs, well abundant natural sources, generally non-toxic nature, ease long-term consumption. This review article examines development explores ‘two-sidedness’ blood–brain barrier (BBB) a nervous system an impeding use drug medicinal products and/or supplements prevention therapy reviews BBB permeability common suplements efficacy treatment NDs.

Using Redox Proteomics to Gain New Insights into Neurodegenerative Disease and Protein Modification

Antioxidants, Journal Year: 2024, Volume and Issue: 13(1), P. 127 - 127

Published: Jan. 20, 2024

Antioxidant defenses in biological systems ensure redox homeostasis, regulating baseline levels of reactive oxygen and nitrogen species (ROS RNS). Oxidative stress (OS), characterized by a lack antioxidant or an elevation ROS RNS, may cause modification biomolecules, being primarily absorbed proteins. As result both genome environment interactions, proteomics provides complete information about cell’s proteome, which changes continuously. Besides measuring protein expression levels, can also be used to identify modifications, localizations, the effects added agents, interactions between Several oxidative processes are frequently modify proteins post-translationally, including carbonylation, oxidation amino acid side chains, glycation, lipid peroxidation, produces highly alkenals.
