Researchers have identified a small family of flu-fighting proteins that somehow increases natural resistance to viral infection. The proteins block most virus particles from infecting the cell at the earliest stage in the virus lifecycle.
Scientists discover natural flu-fighting protein in human cells
In findings that may lead to better ways to prevent and treat influenza and other viral infections, researchers report the discovery of a family of naturally occurring antiviral agents in human cells. In experiments in human and mouse cells, the flu-fighting proteins prevented or slowed most virus particles from infecting cells at the earliest stage in the virus lifecycle.
