Persistent Pain Associated With DNA Changes In Brain And Immune Systems

Renaud Massart et al from McGill University have recently published an article in Scientific Reports on the effects of chronic pain on the body. “Chronic pain” is pain that has lasted for 6 months or more. The study was performed on rats with induced nerve injuries.

The results showed epigenetic┬áchanges in the DNA of the prefrontal cortex and in the DNA of T cells. Their findings support the notion that persistent pain affects multiple biological systems. It’s possible that future research will show changes to other systems as well.
