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 ...

Chikungunya virus is a positive-sense single-stranded RNA virus for which no antiviral therapy has been approved. Nucleotide analogues are among the most promising broad-spectrum antivirals, as they ...

Scientists are uncovering viral features that blur the boundary between living and non-living, from giant viruses with protein-making tools to mysterious RNA entities in our microbiomes. These ...
