Researchers identify a shared RNA-protein interaction that could lead to broad-spectrum antiviral treatments for enteroviruses ...

The innate immune system is the body's first line of defence against pathogens like bacteria or viruses. TRIM25 is a protein that is important in the innate immune response against RNA viruses, such ...

Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals ...

Human norovirus, a positive-strand RNA virus that is the leading cause of viral gastroenteritis accounting for an estimated 685 million cases and approximately 212,000 deaths globally per year, has no ...

Researchers at Utah State University have reported a previously unrecognised CRISPR immune response in which a bacterial ...

The world is absolutely teeming with viruses. The infectious agents are widely considered the most abundant biological entity on Earth. But a full understanding of viruses and the roles they play in ...

Biologists mapping the human microbiome expected to find new bacteria and viruses, not entities that slip through every ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have emerged more times than previously thought. Corroborating the virus-first ...

A new study has explored the RNA-binding mechanisms of the antiviral protein TRIM25. TRIM25 (green, left) finds its way to the same locations in the cell where a virus (red, middle) replicates. The ...
