Axotomy of peripheral nerve triggers events that coordinate a limited inflammatory response to axonal degeneration and initiation of neurite outgrowth. Inflammatory and neurite outgrowth-promoting roles for the receptor for advanced glycation end products (RAGE) have been suggested, so we tested its role in peripheral nerve regeneration. Analysis of immunohistochemical localization of RAGE by c...

JAM-C is a junctional adhesion molecule, enriched at tight junctions on endothelial and epithelial cells, and also localized to Schwann cells at junctions between adjoining myelin end loops. The role of JAM-C following peripheral nerve injury (PNI) is currently unknown. We examined the localization of JAM-C after sciatic nerve crush injury in adult rats. JAM-C immunoreactivity was present in pa...

An increasing weight of evidence implicates early inflammatory events as inhibitors of functional recovery in both peripheral and central neuropathologies. In this study, we investigated the role of the inflammatory TNF-α/NF-κB axis on events subsequent to sciatic nerve crush injury in rats. Electrophoretic mobility shift assays (EMSA) revealed that within 6 hours post-crush NF-κB DNA binding a...

BACKGROUND Bogijetong decoction (BGJTD) is a herbal drug formulation used in the traditional Asian medicine to treat neuropathic insults associated with diabetes and anticancer therapy. To understand the biological basis of BGJTD on protective effects against neuropathy, we investigated physiological and biochemical responses of the sciatic nerves deranged by taxol injection or crush injury in ...

  Objective (s): Scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. Several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. This study evaluates the translational capacity of four of physical injury models to induce scar formation aro...

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...

repairing the damaged nerves caused by physical injury (trauma), is one of the major challenges facing modern medical sciences. evening primrose oil (epo) extraction of oenothera biennis seed that enriches with omega-6,γ-linoleic acid and linoleic acid that they have essential role in myelination and neural membrane structure. the aim of this study was to evaluate the functional recovery of sci...

A common cause of peripheral nerve injury is trauma. The positive effect of antioxidants on the improvement of nerve regeneration has currently become a focus of attention. In this experiment, the effect of intraperitoneal administration of ubiquinone (CoQ10) on an acute experimentally sciatic nerve crush was studied in a rat model. Forty-five male Wistar rats, weighing between 160-180 g were u...

Transplantation of bone marrow mesenchymal stem cells (BMSCs) has been developed as a new method of treating diseases of the peripheral nervous system. While netrin-1 is a critical molecule for axonal path finding and nerve growth, it may also affect vascular network formation. Here, we investigated the effect of transplanting BMSCs that produce netrin-1 in a rat model of sciatic nerve crush in...

Background: Peripheral nerve injury causes prolonged functional limitation being a clinical challenge to identify resources that accelerates its recovery. Objectives: To investigate the effect of high-voltage electrical stimulation (HVES) on the morphometric and functional characteristics of the regenerated nerve after crush injury in rats. Methods: Twenty Wistar rats were randomly allocated in...
