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 ...

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 ...

To become infectious, HIV has to undergo a maturation process, which involves a rearrangement of the matrix proteins (red). In an immature virus particle, the matrix proteins form a lose lattice ...

Researchers have discovered a virus that could enter human cells in a similar way to COVID-19. But they caution it's much ...

the virus that causes AIDS – to find out. This transmission electron microscopy image shows HIV viral particles (yellow) near the end of the budding process; the cell they’ve infected is in blue.

Researchers used cryo-EM, glycoproteomics, and modeling to generate the atomic structure of a fully glycosylated and membrane ...

The polymeric nature of the membrane-displayed antigen ... the effectiveness of encounters between B cells and soluble toxin or circulating viruses? The answer may lie, in part, in the innate ...

to merge their membrane with the host cell’s membrane. This allows the virus to enter the cell and start multiplying. Dr Isaacs said the next step in this research is to study the important ...

Supercomputer simulations have revealed how changes in the shape of the HIV-1 capsid protein may help the virus squeeze its inner core into the host cell's nuclear membrane. The findings ...
