Ancient viral fossils buried in our DNA are offering fresh clues about how today’s respiratory pathogens infect and spread.

Most of them come from a subset of viruses called retroviruses, which infect host cells and then trick them into making the ...

The re-transcribed DNA is then integrated into the genome of the host cell (Figure 2). This process requires the absence of the nuclear membrane and thus is restricted to the M-phase of proliferating ...

Explore the enduring challenges of treating HIV, its unique properties, and the progress made since the virus's discovery.

LA JOLLA, CA—You are mostly but not entirely human. If we crunch the numbers, 8 percent of your genome actually comes from viruses that got stranded there. This viral detritus is a souvenir from our ...

Research suggests that ancient viral DNA embedded in the human genome is playing a key role in early embryo development. Around 8% of our genome consists of endogenous retrovirus DNA — the remnants of ...

University of Virginia School of Medicine scientists have uncovered a key reason why HIV remains so difficult to cure, bringing researchers closer to finding ways to flush out the dormant virus and ...

Retroviruses are viruses that have evolved the ability to write their genetic code into a cell's own DNA. The most ancient ...
