From Common virus kills cancer, study finds:
‘Our results suggest that adeno-associated virus type 2, which infects the majority of the population but has no known ill effects, kills multiple types of cancer cells yet has no effect on healthy cells,’ said Craig Meyers, a professor of microbiology and immunology at the Penn State College of Medicine in Pennsylvania.‘We believe that AAV-2 recognizes that the cancer cells are abnormal and destroys them. This suggests that AAV-2 has great potential to be developed as an anti-cancer agent,’ Meyers said in a statement.
He said at a meeting of the American Society for Virology that studies have shown women infected with AAV-2 who are also infected with a cancer-causing wart virus called HPV develop cervical cancer less frequently than uninfected women do.
AAV-2 is a small virus that cannot replicate itself without the help of another virus. But with the help of a second virus it kills cells.
