Friend Virus Budding from T-cell (IMAGE)
Caption
This electron microscope image shows yellow particles of a mouse leukemia virus named Friend virus emerging or "budding" out of an infected white blood cell known as a T-cell. By allowing the Friend virus to mutate and evolve in mice, University of Utah researchers produced new evidence that an arms race between microbes and immune-system MHC genes is responsible for maintaining an amazing diversity of those genes, even though some of them are responsible for autoimmune and infectious diseases that make us sick.
