Study reveals how a Rab protein controls HIV-1 replication

HIV-1 replication requires the coordinated movement of the virus's components toward the plasma membrane of an immune cell, where the virions are assembled and ultimately released. A study in The Journal of Cell Biology reveals ...

Cytomegalovirus hijacks human enzyme for replication

More than 60 percent of the world's population is infected with a type of herpes virus called human cytomegalovirus. The virus replicates by commandeering the host cell's metabolism but the details of this maneuver are unclear.

Team publishes structural basis for HCV RNA replication

In this week's issue of Science, researchers at Gilead Sciences, Inc. and Beryllium reveal new details about how the hepatitis C virus (HCV) replicates its genome. HCV is estimated to affect 150-200 million people worldwide ...

Herpes virus rearranges telomeres to improve viral replication

A team of scientists, led by researchers at The Wistar Institute, has found that an infection with herpes simplex virus 1 (HSV-1) causes rearrangements in telomeres, small stretches of DNA that serve as protective ends to ...

An enzyme that fixes broken DNA sometimes destroys it instead

Enzymes inside cells that normally repair damaged DNA sometimes wreck it instead, researchers at the Stanford University School of Medicine have found. The insight could lead to a better understanding of the causes of some ...

New study reveals why some people may be immune to HIV-1

Doctors have long been mystified as to why HIV-1 rapidly sickens some individuals, while in others the virus has difficulties gaining a foothold. Now, a study of genetic variation in HIV-1 and in the cells it infects reported ...
