These virophages use the viral factory, a temporary organelle formed by the giant virus in the cytoplasm of the infected cell, to ensure their own replication. This phenomenon constitutes a case ...

We know that viruses infect cells, but what does that process actually look like? Sure, diagrams can be helpful, but there’s nothing quite like seeing the real thing. Trouble is, doing so with ...

In a new study, Weizmann Institute of Science researchers reveal a bacterial immune system that thwarts the phages’ plot by attaching a small protein molecule to their tails. The components of this ...

A new study finds tweaking part of the H5N1 virus infecting dairy cows in a single spot could allow it to better attach to ...

developed the ability to infect the first cells. Could today's single-stranded RNA viruses be descendants of these precellular RNA molecules? Others have argued that precursors of today's NCLDVs ...

The virus and lung-cell membranes fuse ... and commit the exercise to memory so it is ready to fight the real virus during an infection. Vaccine makers are pursuing a variety of strategies ...

Now, scientists have discovered that human cells are home to their own hidden superheroes, secretly helping us to fight off a ...

How does the dengue virus infect a cell and replicate itself? In this section, we will explore the answers to these questions. In 1943, Ren Kimura and Susumu Hotta first isolated the dengue virus.

Infectious disease researchers have discovered that a little-known protein, PDGFA-associated protein 1 (PDAP1), is used as a pawn by hepatitis A virus to replicate and infect cells in the liver.

When exposed to the virus, the liver cells lacking PDAP1 were unable to support its replication. The mice were also completely resistant to hepatitis A infection. Without PDAP1, the virus was not able ...

“The emergence of a bovine H5N1 virus capable of recognizing human receptors may be closer than previously thought,” Yoshihiro Kawaoka, a professor at the University of Wisconsin-Madison who studies ...
