An RNA Modification That Stops an Autoimmune Reaction

The human body has to protect itself from pathogens and infectious agents, and there are a variety of ways for the immune system to sense foreign invaders, and react to the threats they may pose. But the body also has to disregard the tissues, cells, and molecules of the self, so they do not trigger aberrant immune responses. Scientists have now identified a chemical modification that happens on RNA molecules, which prevents the immune system from…
