چکیده

Three different myelin proteins, Nogo, MAG, and OMgp, inhibit regenerating axons after CNS injury. New work reveals that they all share a common receptor and that blockade of this receptor promotes CNS repair and functional recovery.

The regenerative deficit of peripheral nerves in experimental diabetes: its extent, timing and possible mechanisms.

Diabetes mellitus is reported to impair peripheral nerve regeneration, but the extent, timing and selectivity of the deficit is unclear. We studied regeneration of motor and sensory fibres in mice with experimental diabetes induced using streptozotocin (STZ). The mouse model featured several advantages over its counterpart in rats given STZ, while exhibiting the expected slowing of motor conduc...

BDNF promotes the axonal regrowth after sciatic nerve crush through intrinsic neuronal capability upregulation and distal portion protection

Nowadays peripheral nerve injurie occurs more common, the outcome is often poor because of the ineffective treatment. Recent researches revealed the duration of BDNF administration acts a positive role during the nerve regeneration, but its potential mechanisms beneath the behavioral recovery and axonal regrowth after peripheral nerve injury are still controversial. To observe the potential mec...

Locally synthesized calcitonin gene-related Peptide has a critical role in peripheral nerve regeneration.

Regeneration of peripheral nerves involves complex and intimate interactions between axons and Schwann cells. Here, we show that local axon synthesis and action of the neuropeptide calcitonin gene-related peptide (CGRP) is critical for this collaboration. After peripheral sural sensory axon injury in rats, we observed an unexpectedly large proportion of axons that newly expressed CGRP during re...

A small molecule screen identifies in vivo modulators of peripheral nerve regeneration in zebrafish

Adult vertebrates have retained the ability to regenerate peripheral nerves after injury, although regeneration is frequently incomplete, often leading to functional impairments. Small molecule screens using whole organisms have high potential to identify biologically relevant targets, yet currently available assays for in vivo peripheral nerve regeneration are either very laborious and/or requ...

Antler regrowth as a form of epimorphic regeneration in vertebrates - a comparative view.

The annual regrowth of deer antlers is a unique case of extensive appendage regeneration in mammals. This review compares basic aspects of antler regeneration with epimorphic regeneration in other vertebrate taxa. The mesenchymal cells that build up the regenerating antler are not derived from dedifferentiated cells in the pedicle stump, but from the proliferation of cells of the pedicle perios...
