Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense ...

The RNA polymerase NS5B of HCV is capable of catalyzing the addition of flavin adenine dinucleotide (FAD) to its RNA as a 5′ cap structure, aiding the virus in evading host immune responses. However, ...

Researchers at San Diego State University and Michigan State University are shedding new light on how viruses meticulously pack their genetic material — a breakthrough that could help researchers ...

Following the first stay-at-home orders issued in the U.S. to curb the spread of COVID-19, gastrointestinal viruses such as norovirus, rotavirus and adenovirus all but disappeared from California ...

Viruses are masters at taking over our cells: They disable our defenses and hijack the cellular machinery in order to multiply successfully. For example, the herpes simplex virus 1, which causes ...

Cas13 is activated by the hybridization of a CRISPR RNA to a complementary single-stranded RNA protospacer in a target RNA. While Cas13 is not activated by double-stranded RNA in vitro, it robustly ...

The findings mark the first documented detection of bat-origin orthoreovirus-a kind of double-stranded RNA virus-in human cases of acute respiratory illness and encephalitis in Bangladesh. The study ...

Mammalian immunity has long been thought to rely solely on proteins and specialized immune cells. However, a newly proposed concept—RNA immunity—is reshaping this perspective. In a recent publication ...
