Mitochondria are essential cell organelles that are best known for their function in cellular energy homeostasis. However, research in the last two decades has unravelled an unexpected complexity of mitochondria and multiple ways how mitochondria interact with their cellular environment. Mitochondria are now recognised as dynamic and plastic organelles that are integrated into a complex network of cellular signalling cascades. They respond to alterations in cellular physiology but by themselves signal to determine cell fate and function. These complex and bi-directional interactions of mitochondria with the cell make it also necessary to revise the view on the role of mitochondria in disease. The CRC 1218 tackles the challenge of mitochondrial complexity using novel interdisciplinary and collaborative approaches. The projects in research area A examine how mitochondrial function adapts to changing physiological demands focussing on mitochondrial plasticity and the regulatory role of mitochondrial dynamics in preserving the functional integrity of mitochondria and the cell. Work in research area B investigates the role of mitochondrial signalling under various stress conditions and in disease. Together, the planned experiments in the CRC 1218 will foster our understanding as to how mitochondria regulate cell function and therefore will provide new insight into the cell-type specificity of mitochondrial diseases.
