Researchers at the University Medical Center Göttingen (UMG) and members of the MBExC have discovered a new quality control mechanism that regulates the energy production in human cells. This process takes place in mitochondria, the power plants of the cell. Malfunctions of mitochondria lead to serious diseases of the nerves, the muscles and the heart. The findings could contribute to the development of new therapies for affected patients. The results have been published in the renowned Molecular Cell journal.
