Mitochondria have primarily been known as the energy-producing components of cells. But scientists are increasingly discovering that these small organelles do much more than just power cells. They are also involved in immune functions such as controlling inflammation, regulating cell death and responding to infections.
Research from my colleagues and I revealed that mitochondria play another key role in your immune response: sensing bacterial activity and helping neutrophils, a type of white blood cell, trap and kill them.
