Cancer botat med HIV...?

The poison was the cure? (Kom inte på något bättre att kommentera det med)

The Penn scientists targeted chroniclymphocytic leukemia (CLL), the most common type of the blood disease. It strikes some 15,000 people in the United States, mostly adults, and kills 4,300 every year. Chemotherapy and radiation can hold this form of leukemia at bay for years, but until now the only cure has been a bone marrow transplant. A bone marrow transplant requires a suitable match, works only about half the time, and often brings on severe, life-threatening side effects such as pain and infection.
In the Penn experiment, the researchers removed certain types of white blood cells that the body uses to fight disease from the patients. 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.
