The spike protein is the main part of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the infection. It consists of two subunits S1 and S2. Upon entry of the virus ...

Researchers assessed the impact of ceramide (CER) and cholesterol (CHOL) on membrane fusion mediated by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein.

But Liu and colleagues noticed that cell fusion depends greatly on host proteases used to break down the spike protein, such as transmembrane serine protease 2 (TMPRSS2). SARS-CoV-2 spike ...

The SARS-CoV-2 virus inserts itself into the membrane of a host human cell using a small part of its spike protein (yellow), called a fusion peptide.

A new computational study suggests that a protein present in SARS-CoV-2, the virus that causes COVID-19, could be a target for future vaccines. The study is published ahead of print in the ...

SARS-CoV-2 hijacks nanotubes between neurons to infect them, study finds Date: July 25, 2022 ... These transient dynamic structures are a result of membrane fusion in distant cells.

3D illustration of a besieged castle. getty. This is the fifth article in a 15-part series called “Relevance of Immune Suppression by SARS-CoV-2 to Understanding and Controlling the Covid-19 ...
