An 85-kb tandem triplication in the slow Wallerian degeneration (Wlds) mouse.
Wallerian degeneration is the degeneration of the distal stump of an injured axon. It normally occurs over a time course of around 24 hr but it is delayed in the slow Wallerian degeneration mutant mouse (C57BL/Wlds) for up to 3 weeks. The gene, which protects from rapid Wallerian degeneration, Wld, previously has been mapped to distal chromosome 4. This paper reports the fine genetic mapping of...
متن کاملProtective role of Wallerian degeneration slow (Wlds) gene against retinal ganglion cell body damage in a Wallerian degeneration model
Nerve distal axon injury-induced Wallerian degeneration is significantly delayed in Wallerian degeneration slow (Wld(s)) mutant mice, although the associated mechanisms are not completely clear and the role of Wld(s) in retinal ganglion cell (RGC) body damage is not fully understood. In the present study, a Wallerian degeneration model was established in wild-type (WT) and Wld(s) mutant mice by...
متن کاملThe slow Wallerian degeneration gene, WldS, inhibits axonal spheroid pathology in gracile axonal dystrophy mice.
Axonal dystrophy is the hallmark of axon pathology in many neurodegenerative disorders of the CNS, including Alzheimer's disease, Parkinson's disease and stroke. Axons can also form larger swellings, or spheroids, as in multiple sclerosis and traumatic brain injury. Some spheroids are terminal endbulbs of axon stumps, but swellings may also occur on unbroken axons and their role in axon loss re...
متن کاملMechanisms of Observed Neuroprotection of Dopaminergic Neurons in Wallerian Degeneration Slow (WldS) Mice
An emerging hypothesis in Parkinson's disease (PD) is that dopaminergic (DA) neurons degenerate through a " dying back " axonopathy wherein degeneration begins in the distal axon and progresses over time towards the cell body. Impaired axonal transport also appears to play an early, pivotal role in PD. Thus processes that delay axonal transport dysfunction and/or axonal degeneration might slow ...
متن کاملPersistence of neuromuscular junctions after axotomy in mice with slow Wallerian degeneration (C57BL/WldS).
The present study was undertaken to examine the fate of neuromuscular junctions in C57BL/WldS mice (formerly known as OLA mice) after nerve injury. When a peripheral nerve is injured, the distal axons normally degenerate within 1-3 days. For motor axons, an early event is deterioration of motor nerve terminals at neuromuscular junctions. Previously, the vulnerability of motor terminals has been...
