.. 14-3-3 zeta protein involved in generating chronic pain Researchers in France and Sweden can see how one of the body’s own proteins is involved in generating chronic discomfort in rats. The results, which also recommend therapeutic interventions to alleviate long-lasting pain, are reported in The EMBO Journal. Chronic pain is persistent and often difficult to treat. It is due, at least in part, to changes in molecular signalling events that happen in neurons, alterations that can ultimately disrupt the transmitting of nerve signals from the spinal-cord to the mind. We have been fortunate to possess a wide variety of technologies that allow us to look even more specifically at the molecular occasions that result in the onset of chronic pain in pets, said Marc Landry, lead author of the scholarly research and Professor at the University of Bordeaux.
