Posttraumatic nerve recovery remains a challenge in regenerative medicine. As such, there is a need for agents that limit nerve damage and enhance nerve regeneration. Here we investigate rosuvastatin, a 3-hydroxy-3-methylglutaryl coenzyme (HMG-CoA) reductase inhibitor, with anti-inflammatory and antioxidant properties. We explore its neuroprotective properties on sciatic nerve crush injury in male Wistar Rats. Rats were subjected to crush injury to the left sciatic nerve using a vessel clamp for 30 s. Rosuvastatin or vehicle was prepared daily and administrated by oral gavage for seven days post-injury. In rosuvastatin treatment groups, rosuvastatin was administrated at the doses of (5 or 10 mg/kg) in the treatment group. The control group was given a vehicle in the same manner. Behavioral, electrophysiological, morphological and molecular parameters were examined during the recovery process. Chronic administration of rosuvastatin at all doses after sciatic nerve crush markedly promoted nerve regeneration and significantly accelerated motor function recovery (P < 0.05). Electrophysiological, morphological and molecular parameters also improved in the rosuvastatin treatment groups compared to the controls. These findings suggest that neuroprotective effects of rosuvastatin could be due to its antioxidant and anti-inflammatory activity. It is clear that more research is needed to confirm these findings.

Changes in DNA methylation and subsequent alterations in gene expression have opened a new direction in research related to the pathogenesis of peripheral neuropathic pain (PNP). This study aimed to reveal epigenetic perturbations underlying DNA methylation in the dorsal root ganglion (DRG) of rats with peripheral nerve injury in response to prior exercise and identify potential target genes involved. Male Sprague-Dawley rats were divided into three groups, namely, chronic constriction injury (CCI) of the sciatic nerve, CCI with prior 6-week swimming training (CCI_Ex), and sham operated (Sham).

Peripheral nerve injury (PNI) as a common clinical issue that presents significant challenges for repair. Factors such as donor site morbidity from autologous transplantation, slow recovery of long-distance nerve damage, and deficiencies in local cytokines and extracellular matrix contribute to the complexity of effective PNI treatment. It is extremely urgent to develop functional nerve guidance conduits (NGCs) as substitutes for nerve autografts.

Charcot-Marie-Tooth disease type 1A (CMT1A) is an inherited peripheral neuropathy caused by a duplication of the peripheral myelin protein 22 (PMP22) gene. It is primarily marked by Schwann cell dedifferentiation and demyelination, leading to motor and sensory deficits. Cyclic adenosine monophosphate (cAMP) is crucial for Schwann cell differentiation and maturation.

Neuropathic pain is a disorder affecting the somatosensory nervous system. However, this condition is also characterized by significant neuroinflammation, primarily involving CNS-resident non-neuronal cells. A promising target for developing new analgesics is histamine H receptor (HR); thus, we aimed to determine the influence of a novel HR antagonist/inverse agonist, E-98 (1-(7-(4-chlorophenoxy)heptyl)-3-methylpiperidine), on pain symptoms and glia activation in model of neuropathic pain in male mice (chronic constriction injury to the sciatic nerve).

As the clinical applicability of peripheral nerve stimulation (PNS) expands, the need for PNS-specific safety criteria becomes pressing. This study addresses this need, utilizing a novel machine learning and computational bio-electromagnetics modeling platform to establish a safety criterion that captures the effects of fields and currents induced on axons. Our approach is comprised of three steps: experimentation, model creation, and predictive simulation.
