Oxidative Stress Markers in Multiple Sclerosis
https://pubmed.ncbi.nlm.nih.gov/38927996/
Data from analyses of central nervous system autopsy material from patients diagnosed with multiple sclerosis, as well as from studies in the main experimental model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE), suggest the possibility of a role of oxidative stress as well ..

Multiphase Radical Chemical Processes Induced by Air Pollutants and the Associated Health Effects
https://pubmed.ncbi.nlm.nih.gov/39839244/
Abstract
Air pollution is increasingly recognized as a significant health risk, yet our understanding of its underlying chemical and physiological mechanisms remains incomplete. Fine particulate matter (PM2.5) and ozone (O3) interact with biomolecules in intracellular and microenvironments, such as the epithelial lining fluid (ELF), leading to the generation of reactive oxygen species (ROS). These ROS trigger cellular inflammatory responses and oxidative stress, contributing to a spectrum of diseases affecting the respiratory, cardiovascular, and central nervous systems. Extensive epidemiological and toxicological research highlights the pivotal role of ROS in air pollution-related diseases. It is crucial to comprehend the intricate chemical processes and accompanying physiological effects of ROS from air pollutants...

The impact of oxidative stress on symptoms associated with multiple sclerosis
https://pubmed.ncbi.nlm.nih.gov/40596531/
Abstract
Multiple sclerosis (MS) is a chronic, inflammatory and degenerative disease affecting the central nervous system, the pathophysiology of which is unknown. Oxidative stress appears to play a significant role in the initiation and the perpetuation of the inflammatory and neurodegenerative processes associated with MS...

Ozone-induced Neurotoxicity: Mechanistic Insights and Implications for Neurodegenerative Diseases
https://pubmed.ncbi.nlm.nih.gov/40641015/
Abstract
Ozone (O3), a reactive gas produced by sunlight-driven reactions involving nitrogen oxides and volatile organic compounds, presents serious risks to both respiratory and brain health. While its harmful effects on the lungs are well established, there is increasing evidence connecting ozone exposure to cognitive decline and neurodegenerative conditions like Alzheimer's and Parkinson's diseases. Ozone induces oxidative stress and systemic inflammation, and activates microglia, with the potential to reach the brain directly through the olfactory pathway. These mechanisms play a role in key neurodegenerative processes, such as the buildup of amyloid-beta, abnormal tau phosphorylation, and mitochondrial dysfunction. Drawing from findings in both animal and human studies, this review highlights the critical need to reduce ozone exposure to safeguard brain health and alleviate the growing impact of neurological disorders.
