Scientists identify gene behind our reaction to flu-type viruses
Researchers have identified, for the first time, a human gene responsible for our susceptibility and response to flu and other viruses.
The gene – IFITM3 – produces a protein that protects cells against infections and is thought to be critical in the immune system’s response against viruses such as swine flu. The study found that patients who ended up in intensive care with potentially fatal complications after developing flu were much more likely to have a variant of this gene that did not protect against the virus.
