In each of the patients as much as five pounds of cancerous tissue completely melted away in a few weeks, and a year later it is still gone. The results of the preliminary test “exceeded our wildest expectations,” says immunologist Dr. Carl June a member of the Abramson Cancer Center's research team. Using a modified, harmless version of HIV, the virus that causes AIDS, they inserted a series of genes into the white blood cells. These were designed to make to cells target and kill the cancer cells. After growing a large batch of the genetically engineered white blood cells, the doctors injected them back into the patients.
