text: Even in the hospital, doctors can't do much more than offer supportive care. But, with a new study, researchers at the University of Pennsylvania and colleagues have identified a subset of viral products that are responsible for eliciting a strong immune response against RSV in people who become infected.
  RSV, labeled with GFP to glow green, infects a sample of lung tissue from a deceased donor. New research shows that the virus produces defective genomes that prompt the immune system to eliminate the pathogen.
  These products, called immunostimulatory defective viral genomes, or DVGs, were once thought to have no biological function. Now they are being eyed as a gateway through which the immune system could be coaxed to mount a defense to clear the body of the virus.
