Lentivirus-mediated overexpression of netrin-1/DCC co-expression promotes axonal regeneration and functional recovery in spinal cord injury via the inhibition of the NgR1-RhoA-ROCK signaling pathway.

Spinal cord injury (SCI) seriously affects the health of humans and quality of life, causing disabilities. Due to the ever-increasing traffic and cases of natural disasters, such as earthquakes, the incidence of SCI increases every year, thus causing a huge economic burden to society and patients. The lack of neurotrophic factors in the area affected by SCI and the presence of inhibitory factors for axonal regeneration are important reasons that make spinal cord regeneration and repair extremely difficult.
