As power plants and energy stores, mitochondria are essential components of almost all cells in plants, fungi and animals. Until now, it has been assumed that these functions underlie a static structure of mitochondrial membranes. Researchers at the Heinrich Heine University Düsseldorf (HHU) and the University of California Los Angeles (UCLA), supported also by the Center for Advanced Imaging (CAi) of HHU, and have now discovered that the inner membranes of mitochondria are by no means static, but rather constantly change their structure every few seconds in living cells. This dynamic adaptation process further increases the performance of our cellular power plants. “In our opinion, this finding fundamentally changes the way our cellular power plants work and will probably change the textbooks,” says Prof. Dr. Andreas Reichert, Institute of Biochemistry and Molecular Biology I at the HHU. The results are described in a publication in EMBO Reports.
