Myelinogenic Plasticity of Oligodendrocyte Precursor Cells following Spinal Cord Contusion Injury.

Literature context:


Spontaneous remyelination occurs after spinal cord injury (SCI), but the extent of myelin repair and identity of the cells responsible remain incompletely understood and contentious. We assessed the cellular origin of new myelin by fate mapping platelet-derived growth factor receptor α (PDGFRα), Olig2+, and P0+ cells following contusion SCI in mice. Oligodendrocyte precursor cells (OPCs; PDGFRα+) produced oligodendrocytes responsible for de novo ensheathment of ∼30% of myelinated spinal axons at injury epicenter 3 months after SCI, demonstrating that these resident cells are a major contributor to oligodendrocyte regeneration. OPCs also produced the majority of myelinating Schwann cells in the injured spinal cord; invasion of peripheral myelinating (P0+) Schwann cells made only a limited contribution. These findings reveal that PDGFRα+ cells perform diverse roles in CNS repair, as multipotential progenitors that generate both classes of myelinating cells. This endogenous repair might be exploited as a therapeutic target for CNS trauma and disease.SIGNIFICANCE STATEMENT Spinal cord injury (SCI) leads to profound functional deficits, though substantial numbers of axons often survive. One possible explanation for these deficits is loss of myelin, creating conduction block at the site of injury. SCI leads to oligodendrocyte death and demyelination, and clinical trials have tested glial transplants to promote myelin repair. However, the degree and duration of myelin loss, and the extent and mechanisms of endogenous repair, have been contentious issues. Here, we use genetic fate mapping to demonstrate that spontaneous myelin repair by endogenous oligodendrocyte precursors is much more robust than previously recognized. These findings are relevant to many types of CNS pathology, raising the possibility that CNS precursors could be manipulated to repair myelin in lieu of glial transplantation.

Nogo-A does not inhibit retinal axon regeneration in the lizard Gallotia galloti.

Literature context:


The myelin-associated protein Nogo-A contributes to the failure of axon regeneration in the mammalian central nervous system (CNS). Inhibition of axon growth by Nogo-A is mediated by the Nogo-66 receptor (NgR). Nonmammalian vertebrates, however, are capable of spontaneous CNS axon regeneration, and we have shown that retinal ganglion cell (RGC) axons regenerate in the lizard Gallotia galloti. Using immunohistochemistry, we observed spatiotemporal regulation of Nogo-A and NgR in cell bodies and axons of RGCs during ontogeny. In the adult lizard, expression of Nogo-A was associated with myelinated axon tracts and upregulated in oligodendrocytes during RGC axon regeneration. NgR became upregulated in RGCs following optic nerve injury. In in vitro studies, Nogo-A-Fc failed to inhibit growth of lizard RGC axons. The inhibitor of protein kinase A (pkA) activity KT5720 blocked growth of lizard RGC axons on substrates of Nogo-A-Fc, but not laminin. On patterned substrates of Nogo-A-Fc, KT5720 caused restriction of axon growth to areas devoid of Nogo-A-Fc. Levels of cyclic adenosine monophosphate (cAMP) were elevated over sustained periods in lizard RGCs following optic nerve lesion. We conclude that Nogo-A and NgR are expressed in a mammalian-like pattern and are upregulated following optic nerve injury, but the presence of Nogo-A does not inhibit RGC axon regeneration in the lizard visual pathway. The results of outgrowth assays suggest that outgrowth-promoting substrates and activation of the cAMP/pkA signaling pathway play a key role in spontaneous lizard retinal axon regeneration in the presence of Nogo-A. Restriction of axon growth by patterned Nogo-A-Fc substrates suggests that Nogo-A may contribute to axon guidance in the lizard visual system. J. Comp.
