(Why it does this is unclear, but scientists believe it's a clever way for staph, which can't move by itself, to spread beyond the molasses - like environment created when DNA leaks from infected, dying cells.)

Previously, Dr. Smeyne and his collaborator Dr. Stacey Schultz - Cherry in the Department of Infectious Disease at St. Jude Children's Research Hospital in Memphis, TN, showed that a deadly H5N1 strain of influenza (so - called Bird Flu) that has a high mortality rate (60 percent of those infected died from the disease) was able to infect nerve cells, travel to the brain, and cause inflammation that, the researchers showed, would later result in Parkinson's - like symptoms in mice.

One of the paper's co-authors, Hugh Willison, who studies GBS at the University of Glasgow in Scotland, says it's possible that something more subtle is happening: Like other viruses, the one that causes Zika hijacks a cell's own replication machinery to make new copies of itself, which then break out of the dying cell and infect neighboring cells.

In tests using human neural progenitor cells (NPCs)-- self - renewing, multipotent cells that generate neurons and other brain cell types — the scientists found that exposure to sofosbuvir not only rescued dying NPCs infected with the Zika virus, but restored gene expression linked to their antiviral response.

Earlier research had shown that cells surrounding an HIV - infected cell die as a result of apoptosis, or programmed cell suicide, and scientists knew that Nef had a hand in starting that process.

The virus selectively infects cells that form the brain's cortex, or outer layer, making them more likely to die and less likely to divide normally and make new brain cells.

Treatment that targets the DNA in HIV - infected cells has been challenging because the persistent, incurable human immunodeficiency virus is able to insert its own DNA into the DNA of any infected cell while disabling that cell's ability to die to save other cells from a viral invasion.

Many of the infected cells died, and others showed disrupted expression of genes that control cell division, indicating that new cells could not be made effectively.

Five years ago, the group reported that when they infected human tonsil cells with HIV in culture, 95 percent of the CD4 + T cells that died did so before the virus had a chance to reproduce within them.

They were examining the blood of a koala dying of leukemia when they came across a virus infecting its white blood cells.

If HIV killed off all of the infected target cells upon transmission, the virus would die out, as there would be nowhere left for it to spread.
