Article: Cells Carry ‘Memory’ of Injury, Which Could Reveal Why Chronic Pain Persists [Medical Xpress]

“In the study, published today in Cell Reports, they found that nerve damage changes epigenetic marks on some of the genes in these immune cells. Epigenetics is the process that determines which gene is expressed and where. Some epigenetic signals have direct functional consequences, while others are just primers: flags that indicate a potential to act or be modified.

“The cells examined in this King’s study still behaved as normal, but the existence of these novel epigenetic marks may mean that they carry a ‘memory’ of the initial injury.”

 

“Dr Giovanna Lalli, Neuroscience & Mental Health Senior Portfolio Developer at the Wellcome Trust, which part-funded the study, said: ‘People develop chronic pain for a huge variety of reasons. We therefore need an equally diverse range of treatments to tackle the different root causes.

‘The clues from this study, suggesting epigenetic changes may be involved in pain persisting, will hopefully lead us to better understand the mechanisms underlying chronic pain.'”
