Wallerian degeneration is a fundamental process of axonal degeneration distal to the injury site. Although axonal degeneration itself is accomplished in a few days, the subsequent process of removing debris, including myelin debris, in the central nervous system takes more time. Since this debris is a potent inhibitor of axonal regeneration, the removal process is critical for functional recove...
Axons damaged by acute injury, toxic insults, or during neurodegenerative diseases undergo Wallerian or Wallerian-like degeneration, which is an active and orderly cellular process, but the underlying mechanisms are poorly understood. Drosophila has been proven to be a successful system for modeling human neurodegenerative diseases. In this study, we established a novel in vivo model of axon in...
Callosotomy by radioneurosurgery induces slow and progressive axonal degeneration of white matter fibers, a key consequence of neuronal or axonal injury (radionecrosis). However, the acute effects are not apparent when using conventional MRI techniques. Diffusion tensor imaging (DTI) during the first week following radioneurosurgical callosotomy allowed evaluation of these microstructural chang...
OF THE DISSERTATION Mitofusin 2 Regulated Transport of Mitochondria is Necessary for Axonal Integrity By Albert Lawrence Misko Doctor of Philosophy in Biology and Biomedical Sciences Neurosciences Washington University in St. Louis, 2012 Professor Robert Baloh, Chairperson The ubiquitous finding of axonal degeneration in a number of the most prevalent neuropathologies marks the importance of un...
Injured CNS axons fail to regenerate and often retract away from the injury site. Axons spared from the initial injury may later undergo secondary axonal degeneration. Lack of growth cone formation, regeneration, and loss of additional myelinated axonal projections within the spinal cord greatly limits neurological recovery following injury. To assess how central myelinated axons of the spinal ...
Neuronal loss and axonal degeneration are important pathological features of many neurodegenerative diseases. The molecular mechanisms underlying the majority of axonal degeneration conditions remain unknown. To better understand axonal degeneration, we studied a mouse mutant wabbler-lethal (wl). Wabbler-lethal (wl) mutant mice develop progressive ataxia with pronounced neurodegeneration in the...
