“We now have a better understanding as to why high-frequency stimulation helps attenuate inflammation and associated pain.”
“Until now, assessment of pain has been largely subjective. We now have a quantitative biomarker that correlates directly with pain symptoms and allows us to develop more effective treatments,” added Timir Datta, PhD, assistant professor at the Institute of Bioelectronic Medicine at the Feinstein Institutes. “This inflammatory biomarker released by neurons gives us new insight into the role of neuroinflammation in chronic pain.”
Further research is needed to understand better the effect HFES has on reducing pain and inflammation, including the potential for HFES to be used as an alternative for opioids. More complete evaluations on the timing (how long, how frequently), ideal waveform and determination placement of electrodes will help advance this novel technology as a viable therapy for chronic pain.
“The discovery that neurons produce molecules that cause inflammation represents a major advance,” said Kevin J. Tracey, MD, president and CEO of the Feinstein Institutes, Karches Family Distinguished Chair in Medical Research and senior author on the paper. “Now this exciting new work shows it is possible to stop inflammation by targeting these neurons with bioelectronic devices.”
Drs. Chavan and Yang continue to advance the field of bioelectronic medicine, which combines identifying molecular targets, neuroscience and bioengineering to study how to use devices to treat diseases and injury. In a 2021 study published in Proceedings of the National Academy of Sciences of the United States of America (PNAS), the researchers showed that nerves release a molecule, HMGB1, to produce inflammation in the body, which could lead to a new strategy to develop pharmaceutical and bioelectronic therapies. This observation has been advanced in the current study utilizing HFES to target HMGB1 released by nerves.
The research study was funded in part by TrueRelief®.
