Mitochondrial fission/fusion dynamics and apoptosis.
Mitochondria play an important role in the progression of apoptosis through the release of pro-apoptotic factors, such as cytochrome c, from the mitochondrial intermembrane space. During this process, mitochondrial networks are dramatically reorganised from long filamentous interconnected tubules into small punctate spheres. Whether remodelling of mitochondrial networks is necessary for apoptos...
متن کاملMitochondrial Morphological Features Are Associated with Fission and Fusion Events
Mitochondria are dynamic organelles that undergo constant remodeling through the regulation of two opposing processes, mitochondrial fission and fusion. Although several key regulators and physiological stimuli have been identified to control mitochondrial fission and fusion, the role of mitochondrial morphology in the two processes remains to be determined. To address this knowledge gap, we in...
متن کاملMitochondrial fission and fusion.
Mitochondria are highly dynamic cellular organelles, with the ability to change size, shape and position over the course of a few seconds. Many of these changes are related to the ability of mitochondria to undergo the highly co-ordinated processes of fission (division of a single organelle into two or more independent structures) or fusion (the opposing reaction). These actions occur simultane...
متن کاملEmergence of the Mitochondrial Reticulum from Fission and Fusion Dynamics
Mitochondria form a dynamic tubular reticulum within eukaryotic cells. Currently, quantitative understanding of its morphological characteristics is largely absent, despite major progress in deciphering the molecular fission and fusion machineries shaping its structure. Here we address the principles of formation and the large-scale organization of the cell-wide network of mitochondria. On the ...
متن کاملMitochondrial dynamics–fusion, fission, movement, and mitophagy–in neurodegenerative diseases
Neurons are metabolically active cells with high energy demands at locations distant from the cell body. As a result, these cells are particularly dependent on mitochondrial function, as reflected by the observation that diseases of mitochondrial dysfunction often have a neurodegenerative component. Recent discoveries have highlighted that neurons are reliant particularly on the dynamic propert...
