Description
Summary:Nerve injury caused by chemotherapy drugs is a common side effect. How to reduce this kind of nerve injury and promote neuron recovery is of great significance. In this study, we found that tumor necrosis factor-α (TNF-α) promoted the recovery of dorsal root ganglion (DRG) neuron from cisplatin-induced injury. On DRG neurons cultured in vitro, we found that TNF-α promoted neurite regeneration after cisplatin injury. In addition, TNF-α accelerated the removal of DNA damage and promoted the regeneration of mitochondria on DRG neurons. Study of the mechanism showed that this effect of TNF-α was independent from the NGF signaling pathway and occurred mostly through the activation of TNFR2 receptors, together with nucleus translocation of p65 and upregulation of NF-κB expression. This study provides a new theoretical basis and therapeutic strategy for the treatment of nerve injury caused by chemotherapy drugs.
