The virus that commonly causes cold sores starts reshaping our genome within an hour of infection to boost its own growth, which scientists could take advantage of to treat severe cases.

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

Topoisomerase I, an enzyme that snips DNA to release torsional stress, and cohesin, a structural protein, followed human RNA-polymerase II into the newly forming viral replication compartments.

Human DNA in its natural state inside cells (left) compared to eight hours after being infected with HSV-1 (right). The virus compacts the human genome’s size significantly and moves it towards ...

The DNA is taken up into the host cell, translated, and the protein product expressed. Viral protein is made intracellularly and the protein is processed via the endogenous MHC class I pathway.

Maternal vaccination against the virus during pregnancy appeared to offer some protection from those changes in the piglets. The findings are reported in the journal Veterinary Microbiology.

To counter cellular defenses, RNA viruses disrupt cellular gene expression, leading to widespread mRNA decay and facilitating uninterrupted viral replication. Fundamentally, viral RNA genome biology ...
