Mitochondria are membrane-enclosed organelles found in most eukaryotic cells. These organelles are sometimes described as « cellular power plants » because they generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in other tasks such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth. Mitochondria have been implicated in several human diseases, including mitochondrial disorders and cardiac dysfunction, and may play a role in the aging process.
Our team is fully dedicated to mitochondrial research through the following three main axes.
We have produced more than one hundred scientific articles. You will find a large part of our publications in PubMed using this query.
