Oxidative Stress

During inflammation, the body produces toxins that can cause oxidative stress on the cells. When this stress builds up, it can damage or even destroy healthy cells in different parts of the body, including the central nervous system (CNS).

Nrf2 Pathway

One way the body reacts to oxidative stress is through a pathway called Nrf2, short for nuclear factor (erythroid-derived 2)-like 2. This pathway is an important part of a complex communication system involved in the body's response to oxidative stress.

Dimethyl Fumarate

Researchers have learned that dimethyl fumarate, the active ingredient of in TECFIDERA, activates the Nrf2 pathway in our cells. Much about how TECFIDERA works in the body remains unknown, but talking with your doctor can help you learn more about your treatment options.
