Chronic pain afflicts billions of people. It’s time for a revolution.
To overcome this problem, one of the major projects funded by HEAL focuses on studying the nervous systems of people with chronic pain more directly, in part by recovering malfunctioning dorsal root ganglia and trigeminal nerves from patients undergoing surgery for chronic pain, as well as from cadaver donors. . These samples are then cultured and examined using a range of new technologies – things like proteomics, spatial transcriptomics and metabolomics – to see how they differ from normal tissue. The goal, Gereau explained, is to identify what changes occur at the cellular level when pain becomes chronic and to create an atlas of those mechanisms and variations. Understanding this, he added, would eventually open the door to precision medicine, in which drugs could be designed to specif...
