Cold Virus Joins Cancer Fight

Posted Apr 7, 08 2:14 PM CDT in Science & Health    Editor's Choice

(Newser) – Scientists are trying to beat some of the most untreatable forms of cancer by employing another undefeated ailment: the common cold. A research team in Seattle has "modified the viruses so they can selectively target the tumor cells, replicate inside them and kill them," says one of the scientists, but so far just in mice. Deploying viruses against cancer isn't a new technique, reports the Post-Intelligencer.

A century ago, doctors noticed a woman's tumor shrinking after she was vaccinated for rabies. In the 1950s scientists began injecting cancer patients with viruses, hoping for similar outcomes. The new approach is about to start human trials, but some issues aren't resolved. Most critical: how to keep the body from fighting off the helpful virus. Says another researcher: "The trick is to make them kill only the cells you want them to kill."
