By infecting mice with a laboratory created virus scientists at Duke University have successfully cured brain tumors in mice, according to a statement from the American Society of Microbiology. The results were announced at the 101st General Meeting of the American Society for Microbiology.
Malignant glioma is the most common type of brain tumor and is almost always fatal.
The animals recovered within days following a single dose, according to Gromeier. The poliovirus normally causes a cripling neural disease. Rhinovirus is one of the viruses that causes the common cold. The scientists rendered the poliovirus harmless by inserting a piece of genetic information of rhinovirus into the poliovirus genome. Gromeier and his colleagues began investigating use of the poliovirus when it was discovered that it binds to an abnormally expressed molecule on malignant gliomas.
