One in five people worldwide suffers from chronic inflammatory pain. Meanwhile, about two thirds of those affected find little relief from existing pain medications; new therapeutic approaches are urgently needed. "We first must understand precisely how sensory nerve cells trigger pain at the molecular level—in other words, which proteins are involved," says Professor Gary Lewin, Group Leader of the Molecular Physiology of Somatosensory Perception lab at the Max Delbrück Center in Berlin.
