New research reveals that triggering a cell’s DNA damage response could be a promising avenue for developing novel treatments against several rare but devastating viruses for which no antiviral ...

Researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in host cells. University ...

University of Pittsburgh researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in ...

The vaccinia virus uses its own machinery and not that of the cell it infects to repair ultraviolet radiation-caused damage to its DNA, according to new research. The virus repurposes an enzyme it ...

The cold sore-causing Herpes Simplex Virus (HSV-1) hijacks human cells and reconfigures its DNA within just an hour after infection, according to a new study that may help tackle the pathogen. Viruses ...

This story is part of a larger series on viroids and virusoids, small infectious RNAs. It is also the sixth installment in a series on hepatitis D virus, a virusoid-like pathogen that causes serious ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have ...

Later in HIV's replication cycle, integrase interacts with viral RNA to help the virus spread and infect new cells. Taking on these two distinct roles—first with DNA, then RNA—requires changes to ...

In July 2022, the World Health Organization (WHO) announced that monkeypox was a public health emergency of international concern. And, as of early December 2022, more than 82,000 human monkeypox ...

In this study, led by Nahid Shahabadi from Razi University in Kermanshah, researchers developed an environmentally friendly ...
