After central nervous system injury, the increase in Nogo protein is mediated by Nogo-66 receptor gene, leading to the collapse of growth cones and inhibiting the extension of neuronal neurites. Zhiyuan Li and his team, Heibei Xingtai People's Hospital, China used RNA interference to silence Nogo-66 receptor gene expression in bone marrow mesenchymal stem cells (BMSCs), blocked the inhibitory effect of Nogo protein, promoted the process growth of neurons differentiated by transplanted cells, improved the therapeutic effects and increased the success rate of BMSCs transplantation for repair of central nerve system injuries. These results indicate that Nogo-66 receptor gene plays an important role in secondary nerve injury. These results were published in Neural Regeneration Research (Vol. 9, No. 8, 2014).
