Mitochondria are the powerhouses of the cell. Their dysfunction is the cause and consequence of many disorders, including devastating neurodegenerative diseases such as Parkinson’s. Mitochondria are small organelles that exhibit a complex inner architecture which is crucial for their proper function. However, their small size inhibits the analysis of their inner architecture by conventional light microscopy, thus demanding the resolving power of super-resolution microscopy. By combining light and electron microscopy with molecular biology and biochemistry, we are addressing fundamental questions in mitochondrial biology such as the mechanisms that determine the intricate folding of the inner membrane or the regulatory pathways that control the heterogeneity of mitochondria within a single healthy or diseased cell.
