Striking CryoEM image of SARS-CoV-2

A new study by researchers from the UK and Germany and published on the preprint server bioRxiv in June 2020 reports the results of a detailed study of the S protein on the intact virus, using cryoelectron microscopy (cryoEM) and tomography. This could help understand the conformation of the S protein on the virion and how it interacts with neutralizing antibodies.

A glycan analysis of SARS-CoV-2 ACE2 complex

Researchers in the U.S. have produced molecular dynamic simulations of the Spike protein found on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its interaction with the host cell receptor angiotensin-converting enzyme 2 (ACE2).

Scientists create 'all-atom' model of SARS-CoV-2 spike protein

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the coronavirus disease (COVID-19), an illness that has spread across the globe, infecting more than 9 million people. The novel coronavirus invades cells through "spike proteins," which sticks and binds itself to a host cell.

Researchers produce first fully-glycosylated full-length SARS-CoV-2 spike protein models

The virus SARS coronavirus 2 (SARS-CoV-2) is the known cause of coronavirus disease 2019 (COVID-19). The "spike" or S protein facilitates viral entry into host cells.

Mutational targets of SARS-CoV-2 receptor-binding domain for vaccine-antiviral development

The COVID-19 pandemic has spread throughout the whole world within six months, causing millions of infections and hundreds of thousands of deaths. Yet there is no effective vaccine or antiviral to deal with it.

Combination of antibodies and internal radiation can help fight cervical cancer

The sugar coating on cancer cells helps them thrive, and a new study indicates patients with cervical cancer who make antibodies to those sugars appear to do better when they also receive internal radiation therapy.

Glycans "lock and load" the SARS-CoV-2 spike protein for infection

A new study by scientists from the University of California San Diego, USA and Maynooth University, Ireland and published on the preprint server bioRxiv* in June 2020 reports preliminary results showing that the spike protein of the SARS-CoV-2, as well as its glycan coat, has “hitherto unseen functional and structural” properties. These may be useful in designing novel therapeutics to target this molecule.

Novel insights on SARS-CoV-2 cell entry may inform further vaccine and treatment development

A research group from Harvard Medical School reported two cryo-electron microscopy structures derived from a single preparation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein in their paper available on the preprint server bioRxiv. Understanding the nuances of prefusion and postfusion conformations shed light on viral cell entry and may, in turn, guide the development of vaccines and drugs.

Research on SARS-CoV-2 spike protein may lead to new vaccines and treatments

The virus that causes COVID-19 is studded on its exterior with "spike proteins," a key component in its ability to infect human cells. Two University of Georgia researchers, Rob Woods and Parastoo Azadi, are investigating the proteins and sugars on the surface of the virus with the goal of finding information that could lead to vaccines and therapeutics.

Changes in surface sugarlike molecules help cancer cells to spread

Changes in a specific type of sugarlike molecule, or glycan, on the surface of cancer cells help them to spread into other tissues, according to researchers at the University of California, Davis. Published March 23 in Proceedings of the National Academy of Sciences, the work could lead to diagnostic tests and new therapies to slow or stop the spread of cancers.
