Scientists at Yale University School of Medicine in New Haven have discovered a virus that blocks influenza A.
Researchers have found that rhinovirus, which manifests itself as the common cold, blocks the spread of the H1N1 flu. Reported by The Lancet Microbe.
Specialists from the medical school studied the data of 13 thousand 707 people. Influenza A virus was found in 922 of them, and rhinovirus in 982 patients.
At the same time, both viruses were found in test samples of only 12 patients.
During the experiment, scientists infected cultures of the respiratory tract epithelium of healthy donors with rhinovirus HRV-01A. After 3 days, they have infected with the influenza A virus.
The maximum response of immunity to infection occurred after 72 hours. Four interferon-stimulated ISG genes were also activated in the body. They also encode molecules that block H1N1.
It turned out that the level of suppression of type influenza upon preliminary infection of the cell with rhinovirus is similar to the effect of treatment with interferon.
