The first step for a virus to invade a cell is to cross the cell's plasma membrane, which is a lipid barrier. In general, a virus consists of one or more layers of protein that enclose its viral ...

"It's just in a different location. What's important is the immune response to the virus." SARS-CoV-2 is a large, enveloped ...

Glycoproteins typically bind to receptors on the membrane of a host cell. Viruses that do not bud from the host cell membrane do not have an envelope, so they are called “naked” or ...

The virus and lung-cell membranes fuse. Spike decapitation allows the fusion machinery to unfold. The machinery inserts itself into the cell membrane and a channel forms, allowing N proteins and ...

Understanding the differences between bacteria and viruses is crucial for recognizing how these microorganisms impact our health. While both are microscopic and can cause infections, they differ ...

In both of those cases, virus samples showed that once it was in the body, it mutated in ways that would allow it to stick to cells in the mucous membrane lining the upper respiratory tract. “The ...

Membrane proteins are key targets for therapeutic intervention using antibody biologics. Over 60% of FDA-approved drugs act on these proteins. Studying them is challenging because the proteins must be ...

By following the infection path of selected viruses, from their arrival to the cell surface and intracellular trafficking to their amplification and spreading, we focus on the complex dynamics and ...

In both of those cases, virus samples showed that once it was in the body, it mutated in ways that would allow it to stick to cells in the mucous membrane lining the upper respiratory tract.

A lipid (fatty) covering that surrounds a viral particle. It is derived from the cell membrane of the host cell when the virus buds, or exits, the infected cell. The envelope is important for entry ...

Zika virus is unusual in that it can cross the placenta and enter the fetus, where ANKLE2 is known to play a big role in brain development.
