In a 20-year quest to determine why Listeria bacteria produce a uniquely strong immune response in humans, scientists have found part of the answer: an unsuspected signaling molecule that the bacteria pump out and which ramps up production of interferon by the host. Interferon mobilizes the immune system to fight off bacteria and viruses. According to researchers, the finding could help improve vaccines.
