Gene that protects you from flu identified

March 26, 2012 - London

A key gene has been identified that helps people fight against the flu, say scientists.

Researchers from the Wellcome Trust Sanger Institute and the Roslin Institute at the University of Edinburgh have identified a gene, IFITM3, responsible for the body's response to flu and other viruses, the Independent reported.

It produces a protein that protects cells against infections and is thought to be critical in the battle against viruses such as swine flu.

Scientists think that when the protein is present in large quantities, the spread of flu in the lungs is hindered.
