Wallerian degeneration involves Rho/Rho-kinase signaling.
Local axon degeneration is a common pathological feature of many neurodegenerative diseases, whereas the underlying molecular mechanisms are largely unknown. In this study, we used the degeneration of transected axons, termed "Wallerian degeneration," as a model to examine the possible involvement of Rho. Nogo-66, a myelin-derived inhibitor of axon regeneration, significantly accelerated axon d...
متن کاملCritical signaling pathways during Wallerian degeneration of peripheral nerve
Wallerian degeneration is a critical biological process that occurs in distal nerve stumps after nerve injury. To systematically investigate molecular changes underlying Wallerian degeneration, we used a rat sciatic nerve transection model to examine microarray analysis outcomes and investigate significantly involved Kyoto Enrichment of Genes and Genomes (KEGG) pathways in injured distal nerve ...
متن کاملMicroanatomy of axon/glial signaling during Wallerian degeneration.
How do myelinated axons signal to the nuclei of cells that enwrap them? The cell bodies of oligodendrocytes and Schwann cells are segregated from axons by multiple layers of bimolecular lipid leaflet and myelin proteins. Conventional signal transduction strategies would seem inadequate to the challenge without special adaptations. Wallerian degeneration provides a model to study axon-to-Schwann...
متن کاملMotor axon excitability during Wallerian degeneration.
Axonal loss and degeneration are major factors in determining long-term outcome in patients with peripheral nerve disorders or injury. Following loss of axonal continuity, the isolated nerve stump distal to the lesion undergoes Wallerian degeneration in several phases. In the initial 'latent' phase, action potential propagation and structural integrity of the distal segment are maintained. The ...
متن کاملWallerian degeneration of the pontocerebellar fibers.
Two cases of pontine infarct with Wallerian degeneration (WD) of the pontocerebellar fibers are described. WD of pontocerebellar fibers, seen bilaterally along the transverse pontine fibers, is more visible in the middle cerebellar peduncles and extends into the white matter of the cerebellar hemispheres. Understanding the anatomy of the white matter and the temporal evolution of this degenerat...
