Date: 8.8.2009
In its fight against an **intruding virus**, an enzyme in our **immune system** may sense certain types of viral RNA pairs, according to scientists.
The key lies in a virus' **RNA** - a long molecular chain often used to make proteins - and how it regulates an enzyme called protein **kinase R** (PKR), according to researchers from Penn State, the University of Connecticut and the University of Beijing.
