Nrf2 signaling is a specific cellular pathway that is involved in regulating the body's antioxidant response. It plays a key role in protecting cells from oxidative stress, inflammation, and damage caused by free radicals. Activation of the Nrf2 pathway leads to the upregulation of various antioxidant enzymes and proteins that help cells to defend themselves against harmful environmental factors. Research in this area often focuses on understanding how Nrf2 signaling is regulated, how it interacts with other cellular pathways, and its potential therapeutic applications in treating diseases related to oxidative stress and inflammation.
