It started as a respiratory illness – or so everyone thought. But it quickly became apparent that SARS-CoV-2, the virus that ...

It is a near sphere of protein (cross section shown) inside a fatty membrane that protects a twisting strand of RNA--a molecule that holds the virus's genetic code. Proteins called "S" form spikes ...

As the seasonal flu picks up, there are even more opportunities for the bird flu to acquire mutations as the different ...

Assembly and budding of a virus from a membrane microdomain. Viruses have an outer protein shell called a capsid which surrounds the viral nucleic acid. Enveloped viruses, such as HIV, have an ...

A team of virologists, infectious disease specialists and pathobiologists affiliated with several institutions in China and the U.K. has found possible evidence that bird flu vaccinations are driving ...

Once deep inside the cell, the virus fuses with the endosomal membrane and is released into the cytoplasm. The virus particle comes apart, releasing the viral genome. The viral RNA (vRNA ...

HSV-2 transmits more easily when an area of the body with herpes comes into contact with mucous membranes of a person who does not have the virus. Mucous membranes are moist linings in certain ...

which displays membrane proteins in the membrane envelope of herpes simplex virus-1 (HSV-1) virions. The technology is designed for high-throughput biochemical analysis of membrane proteins.

It is a type of virus known as “non-enveloped” or “naked,” which means that it never acquires the membrane coating typical of other viruses, such as the flu virus. The norovirus surface is a protein ...
