Medical researchers at Washington University School of Medicine and and the University of California San Diego School of Medicine have weaponized a mutated form of the Zika virus in the hopes of defeating a common, highly aggressive form of brain cancer.
They say that initial results against Glioblastoma have been highly promising
According to Michael S. Diamond, Professor of Medicine and the study’s co-senior author: “We showed that Zika virus can kill the kind of glioblastoma [brain cancer] cells that tend to be resistant to current treatments and lead to death”

The findings were published on Sept. 5 in The Journal of Experimental Medicine.
RT reports:
In the tests, conducted on adult mice, the modified Zika virus preferentially infected and killed the cancer stem cells as opposed to the other cells within the tumor or the healthy cells within the test subjects’ brains, unlike the West Nile virus, which is indiscriminate in which cells it attacks.
The weaponized Zika and a saltwater placebo were injected into 18 and 15 mice respectively. The tumors in the Zika-infected mice shrank dramatically and they survived “significantly longer than the ones given saltwater.”
While the Zika virus is incredibly damaging to infants in the womb, leading to microcephaly and other brain malformations in some babies, its effects on adult humans are generally far less severe, with cases of meningoencephalitis rare.
Infant brains have far more stem cells, specifically neuroprogenitor cells, than adult brains, which may explain why the treatment is so promising for adult cancer patients.
Approximately 12,000 people are diagnosed with glioblastoma in the US each year, reports the Washington University of Medicine in St. Louis, among them is US Senator John McCain, who was diagnosed in July.
“We’re going to introduce additional mutations to sensitize the virus even more to the innate immune response and prevent the infection from spreading,” Diamond, a professor of molecular microbiology, added.
“Once we add a few more changes, I think it’s going to be impossible for the virus to overcome them and cause disease.”
A controlled infection with a modified version of Zika in combination with chemotherapy-radiation could one day be used in tandem to defeat this particularly aggressive form of cancer.
“We see Zika one day being used in combination with current therapies to eradicate the whole tumor,” said co-author Milan Chheda, an assistant professor of medicine and neurology, as cited by The Washington University School of Medicine.

There’s been a cure for cancer for years…. They don’t want us to have it – too much money involved…
Dr. Richard Day had said the cure was on file at the Rockefeller Institute in a closed lecture to other doctors in the 1960’s.

I left a few comments.
Unfortunately, given what we know today about cancer (it’s hundreds of different diseases), the likelihood that a magic cure will ever be found is zero. Cancers are so diverse, heterogeneous and mutable that the approach based on looking for one is conceptually absurd.
