Oncogenes of DNA tumor viruses encode proteins that cause cells to divide incessantly, eventually leading to formation of a tumor. These oncoproteins have now been found to antagonize the innate immune response of the cell (link to paper). Most cells encountered by viruses are not dividing, and hence do not efficiently support viral DNA synthesis. The …

On episode #353 of the science show This Week in Virology, the TWiVniacs discuss twenty-eight years of poliovirus shedding by an immunodeficient patient, and packaging of the innate cytoplasmic signaling molecule cyclic GMP-AMP in virus particles. You can find TWiV #353 at www.microbe.tv/twiv.
On episode #336 of the science show This Week in Virology, the TWiVsters explore mutations in the interferon pathway associated with severe influenza in a child, outbreaks of avian influenza in North American poultry farms, Ebolavirus infection of the eye weeks after recovery, and Ebolavirus stability on surfaces and in fluids. You can find TWiV …

Human influenza viruses replicate almost exclusively in the respiratory tract, yet infected individuals may also have gastrointestinal symptoms such as vomiting and diarrhea. In mice, intestinal injury occurs in the absence of viral replication, and is a consequence of viral depletion of the gut microbiota. Intranasal inoculation of mice with the PR8 strain of influenza virus leads …
