SARS-CoV-2 spike pocket is a putative target for antiviral design

In a methodologically rigorous study, researchers from the University of Oxford have recently shown how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein harbors a lipid-binding pocket which modulates the stability of the prefusion trimer and provides conformational shielding from antibodies. Their findings are currently freely available on the bioRxiv* preprint server.

C-type lectin receptors play a role in SARS-CoV-2 infection

A new study published on the preprint server bioRxiv in August 2020 confirms and extends earlier findings showing that a type of sugar-based receptor on innate immune cells promotes the entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into other cells that carry the viral receptor, angiotensin-converting enzyme 2 (ACE2).

SARS-CoV-2 a "swarm" of mutant viruses

In this new study, the virus was serially passaged in independent cell types in a controlled environment. The researchers found that the virus rapidly adapts to the changing conditions in culture by selecting for pre-existing species.

Can SARS-CoV-2 be transmitted via feces?

A new study by researchers at the University of Oxford and the Trip Medical Database and published on the preprint server medRxiv* in August 2020 as part of the ongoing Open Evidence Review on Transmission Dynamics of COVID-19 reports the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in feces and the need for precautions to prevent orofecal spread in the surroundings of confirmed or suspected cases.

Research looks at how long SARS-CoV-2 antibodies last

A new study by researchers at the Fred Hutchinson Cancer Research Center and the University of Washington and published on the preprint server medRxiv* in August 2020 deals with the changes in neutralizing antibodies in the following months.

SARS-CoV-2 infection and transmission possible in North American deer mice

The current COVID-19 pandemic began as a zoonosis in China, at the end of 2019, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel betacoronavirus with significant similarity to an earlier virus of the same family.

USA the source of most of New Zealand's coronavirus cases

New Zealand, an island country in the southwestern Pacific Ocean, is marked by its early and fierce determination to totally arrest the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the viral illness that is causing the current COVID-19 pandemic.

Speed of Novavax vaccine development does not compromise quality of the SARS-CoV-2 immunogen

A new study by researchers from the Scripps Research Institute and Novavax Inc. in the US affirms the structural integrity of the full-length SARS-CoV-2 spike glycoprotein immunogen. It enables the interpretation of immune responses to this multivalent nanoparticle immunogen. Their results are currently available on bioRxiv preprint server.

Encouraging results from Phase I NovaVax SARS-CoV-2 nanoparticle vaccine trial

NVX-CoV2373, a recombinant nanoparticle vaccine developed by Novavax and manufactured at Emergent Biosolutions, was found to be well tolerated and immunogenic – inducing T-cell response and neutralization antibodies four-fold higher than the mean observed in hospitalized coronavirus disease (COVID-19) patients, shows a recent study available on the medRxiv* preprint server.

Study: Drinking honeysuckle decoction accelerates the negative conversion of COVID-19 patients

In a new study in Cell Discovery, Chen-Yu Zhang's group at Nanjing University and two other groups from Wuhan Institute of Virology and the Second Hospital of Nanjing present a novel finding that absorbed miRNA MIR2911 in honeysuckle decoction (HD) can directly target SARS-CoV-2 genes and inhibit viral replication. Drinking of HD accelerate the negative conversion of COVID-19 patients.
