Immune system police are as good at recognizing bad guys, such as bacteria and viruses, as they are our own tissue, researchers say. The finding may cause a stir in the scientific community, which has long held that regulatory T cells or Tregs, preferentially respond to body proteins, or self antigens, rather than non-self antigens, invaders such as viruses and bacteria.
