Antioxidant response is a research area focused on understanding how cells and organisms respond to oxidative stress and damage caused by reactive oxygen species (ROS). Antioxidants are molecules that can inhibit or neutralize the damaging effects of ROS, and studying the antioxidant response involves investigating the mechanisms by which cells regulate the production and activity of antioxidants. This research area is important for understanding various diseases and conditions that are associated with oxidative stress, such as aging, cancer, cardiovascular disease, and neurodegenerative disorders. Additionally, studying the antioxidant response can also help in the development of new strategies for preventing and treating these diseases.
