A study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science ...

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 ...

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...

Researchers identified how the poxvirus protein VITF-3 forms a molecular ring that clamps onto DNA with viral RNA polymerase, bending it by 90 degrees to initiate gene copying.

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 ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

Viruses are entities that have to infect other cells in order to replicate. They may have genomes that are made of DNA or RNA. We are still discovering new types of RNA viruses, as shown in two new ...

Zika virus (ZIKV) is a mosquito-borne orthoflavivirus that can cause birth defects, including microcephaly, a condition in which head and brain size are significantly reduced at birth. The collective ...
