In a quiet freshwater pond in Ibaraki Prefecture near Tokyo, researchers have pulled from the water a microscopic giant that is forcing biologists to rethink how complex life began. The newly ...

The field of molecular epidemiology has brought a transformative perspective to the study of viral infections by integrating molecular data and phylogenetic ...

A new year might mean new viral threats. Influenza A is a perennial threat. The virus infects a wide range of animals and has the ability to mutate rapidly. The most recent influenza pandemic—caused ...

Once the virus attaches to receptor clusters, it sends signals that make the cell wrap it in a clathrin coat and build an actin bulge, pulling the virus inward. The virus is then pinched off into a ...

NEW YORK (PIX11) — A highly contagious virus that spread rapidly across New York City last winter may make a resurgence. Sometimes referred to as the stomach flu or stomach bug, the norovirus illness ...

The only wild specimens of a rare blue parrot, which were recently returned to their natural habitat, have been diagnosed with an incurable, likely lethal virus, Brazil's government told AFP Thursday.

On the left is integrase in its “intasome” structure of four identical four-part complexes (pink) that connect to create one 16-part complex that locks around viral DNA (blue). On the right is ...

A Washington resident has been hospitalized with bird flu, according to the Washington State Health Department, and they’re infected with a strain of the virus that hasn’t been seen in humans before.

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that ...

Viruses are tiny — and sneaky. So sneaky that some play a deadly game of hide and seek. The "seek" part is all too familiar: They're always looking for ways to infect humans. Their ability to hide is ...

Upon administration, VLPs are uptake by APC, like dendritic cells. VLPs can be presented by MHC-I or MHC-II, which are recognized by CD8+ and CD4+ T cells, respectively. For cellular response, CD8+ ...
