Axonal regeneration, but not myelination, is partially dependent on local cholesterol reutilization in regenerating nerve.

A recycling pathway in peripheral nerve permits cholesterol from degenerating myelin to be salvaged by macrophages and resupplied to myelinating Schwann cells by locally produced lipoproteins. A similar reutilization of cholesterol by regenerating axons has been proposed but not demonstrated. Neurites in culture, however, do take up cholesterol and cholesterol-containing lipoproteins, where the...

Necl-4/SynCAM-4 Is Expressed in Myelinating Oligodendrocytes but Not Required for Axonal Myelination

The timing and progression of axonal myelination are precisely controlled by intercellular interactions between neurons and glia in development. Previous in vitro studies demonstrated that Nectin like 4 (Necl-4, also known as cell adhesion molecule Cadm-4 or SynCAM-4) plays an essential role in axonal myelination by Schwann cells in the peripheral nervous system (PNS). However, the role of Necl...

Axonal Regeneration after Sciatic Nerve Lesion Is Delayed but Complete in GFAP- and Vimentin-Deficient Mice

Peripheral axotomy of motoneurons triggers Wallerian degeneration of injured axons distal to the lesion, followed by axon regeneration. Centrally, axotomy induces loss of synapses (synaptic stripping) from the surface of lesioned motoneurons in the spinal cord. At the lesion site, reactive Schwann cells provide trophic support and guidance for outgrowing axons. The mechanisms of synaptic stripp...

Transplantation of Olfactory Mucosa Improve Functional Recovery and Axonal Regeneration Following Sciatic Nerve Repair in Rats

Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...

Cholesterol synthesis and nerve regeneration.

In this report, we examine the requirement of cholesterol biosynthesis and its axonal transport for goldfish optic nerve regeneration. Cholesterol, labeled by intraocular injection of [3H]mevalonolactone, exhibited a delayed appearance in the optic tectum. Squalene and other minor components were labeled but not transported. Following optic nerve crush, the amount of labeled cholesterol transpo...
