How immune cells and exercise affect pain after spinal cord injury
Regulation of SCI-induced pain by macrophages and exercise
This project tests whether changing the activity of immune cells or using exercise-related treatments can reduce long-term nerve pain after spinal cord injury.

What this research studies
Researchers will use an established spinal cord injury model to study how macrophages (a type of immune cell) influence nerve cell excitability and the development of chronic pain. They will shift macrophage activation by providing early post-injury rehabilitation, giving intrathecal exosomes made from stimulated macrophages, or using a phosphodiesterase 4 inhibitor to change signaling inside cells. The team will measure nerve activity and pain-related behaviors to see which approaches prevent or lessen neuropathic pain after injury. The work aims to identify adjuvant therapies for people who cannot begin early rehabilitation after spinal cord injury.
Who could benefit from this research
Good fit: People with spinal cord injury who have or are at risk of developing neuropathic pain, particularly those who could not participate in early rehabilitation, would be the most relevant candidates for related future treatments.
Not a fit: People without spinal cord injury or whose pain comes from unrelated conditions are unlikely to benefit directly from this line of work.
Why it matters
Potential benefit: If successful, this could point to new treatments that lower chronic neuropathic pain after spinal cord injury, especially for patients unable to start early rehab.
How similar studies have performed: Prior research shows early rehab can prevent pain and that macrophages influence chronic pain, but using macrophage-derived exosomes or PDE4 inhibition as therapies remains relatively new and unproven in humans.
