Cellular ROS and Antioxidants: Physiological and Pathological Role.

The document "Cellular ROS and Antioxidants: Physiological and Pathological Role" provides an overview of reactive oxygen species (ROS) and antioxidants and their roles in cellular health and disease. It emphasizes the importance of maintaining a balance between ROS production and antioxidant defense mechanisms. The document explores the dual nature of ROS, discussing both their beneficial and harmful effects, and examines the potential advantages and limitations of antioxidant therapy. It concludes by discussing the significant beneficial effects of antioxidants in reducing the risk of chronic diseases, protecting against aging, and improving immune therapy. The document also highlights the potential deleterious effects of antioxidants and the need for further research to fully understand their biological effects. [Extracted from the article]
