Despite their classic bean-shaped depiction, mitochondria have very different aspects in each cell type. From long filamentous structures to punctuated small round organelles. These shapes can dynamically change in response to nutrients and in situations of metabolic disease. However, why do mitochondria adapt different shapes and how is this determined? In this review, we will aim to understand different visions on how metabolic cues influence mitochondrial shape and vice-versa. This response can be dramatically different between tissues and cells, as illustrated by a large array of genetically engineered mouse models reported to date. We will use these models to understand the role of different mitochondrial dynamics-related proteins and processes.
