In the present study, we examined the effects of topical and systemic administrations of both corticosteroids and melatonin on nerve regeneration in an FN axotomy and neurorrhaphy model.
The expression of MYNN was found to be abnormal during nerve crush or axotomy in extrasynaptic myonuclei, which proved that MYNN is a likely candidate to mediate electrical activity-dependent expression of downstream synapse-specific genes [14].
(86) observed a change in the expression of three miRNAs, miRs 1,16, and 206, in different pain conditions such as peripheral inflammation, nerve ligation, or axotomy. Other studies have employed low-density TaqMan arrays to profile the expression pattern of miRNAs after spinal nerve ligation in rats and found 63 altered miRNAs (87).
[37], on the neuromuscular synapse reaction in various conditions on WldS mice concluded that intensive stimulation in vivo resulted complete nerve blockage in vivo and intensive stimulation ex vivo all reduced synaptic protection mediated by WldSgene expression, providing direct evidence that the rate of neuromuscular synaptic degeneration in response to axotomy is, in fact, sensitive to activity and that either complete disuse or sustained high-frequency stimulation can both cause motor nerve terminals more become vulnerable to potent triggers of degeneration.
Macrophages infiltrate the dorsal root ganglia (DRG) and the sciatic nerve (SN) distal to the site of injury after peripheral nerve axotomy. Injury induced expression of the chemokine CCL2 in the DRG and SN attracts the macrophages to those sites.
