A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildup and oxidative stress.
Researchers led by Prof. An Xu at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have found that a magnetotactic bacterium (MTB) called Magnetospirillum magneticum AMB-1 (AMB-1) can extend healthy lifespan in the Caenorhabditis elegans model. The team also identified the main mechanism behind the effect — suppression of a form of cell death known as ferroptosis.
The findings were published in Free Radical Biology and Medicine.
