Hepatitis A Virus Yields Clues About How Pathogens Survive in the Liver

Viruses infecting the liver cause thousands of cases of liver failure, cancer and death each year. Now, two such viruses, hepatitis A and hepatitis C, have been shown to attack the same part of the immune system, according to a paper published in the Proceedings of the National Academy of Sciences earlier this month. Stanley Lemon, a University of Texas microbiology professor, and his colleagues believe that destroying a protein called mitochondrial antiviral signalling (MAVS) may be a necessary step for viruses seeking to infect the liver.
