Spinal cord injury (SCI) is a traumatic disease of the central nervous system in which a series of cellular responses, such as inflammation and apoptosis, occur near the site of injury due to increased release of biomolecules such as interleukin (IL)-6 and tumor necrosis factor (TNF)-α, as well as some other cytokines (30–32). The gene discussed is TNF; the disease is spinal cord injury.
