  1. 01Kronisk smärta är kopplad till epigenetiska förändringar
  2. 02Hjärnan och immunceller uppvisar liknande metyleringsmönster
  3. 03DNA-metylering i hjärnan korrelerade med smärtnivåer
  4. 04Markörer i T-celler kan möjligen förutsäga kronisk smärta

Epigenetiska markörer i immunceller kan potentiellt fungera som icke-invasiva biomarkörer för kronisk smärta, och spegla förändringar som sker i hjärnan.

Abstract

We tested the hypothesis that epigenetic mechanisms in the brain and the immune system are associated with chronic pain. Genome-wide DNA methylation assessed in 9 months post nerve-injury (SNI) and Sham rats, in the prefrontal cortex (PFC) as well as in T cells revealed a vast difference in the DNA methylation landscape in the brain between the groups and a remarkable overlap (72%) between differentially methylated probes in T cells and prefrontal cortex. DNA methylation states in the PFC showed robust correlation with pain score of animals in several genes involved in pain. Finally, only 11 differentially methylated probes in T cells were sufficient to distinguish SNI or Sham individual rats. This study supports the plausibility of DNA methylation involvement in chronic pain and demonstrates the potential feasibility of DNA methylation markers in T cells as noninvasive biomarkers of chronic pain susceptibility.
