Scientists have discovered that a protein naturally produced by the human body can help protect people and animals from H1N1, according to ScienceDaily.

A team led by Stephen Elledge of Harvard Medical School found that human and mouse cells containing less of the protein IFITM3 are more susceptible to H1N1 and other influenza A viruses. This discovery could lead to the development of new antiviral drugs to treat illness and to prevent transmission among both humans and animals, the Web site reported.
