Researchers have discovered a new pain-suppression pathway in fruit flies that is controlled by just two neurons named ‘Epione’ or ‘Epi’. This breakthrough discovery could have implications for the development of new painkillers and treatments for chronic pain in humans. The molecule that controls this process in adults has an inverse role in larvae, which the researchers say could have implications for how pain is experienced at different stages of development. The study highlights the importance of investigating pain in model organisms like fruit flies to gain a better understanding of the underlying mechanisms of pain in humans.
