Full characterization of mammalian-produced SARS-CoV-2 receptor binding domains

A research paper recently uploaded to the preprint server bioRxiv by Dominguez-Vega et al. (23rd Feb, 2021) describes an in-depth structural analysis of the RBD of the spike protein expressed in mammalian Chinese hamster ovary (CHO) cells and human embryonic kidney (HEK293) cells, providing a new understanding of protein structure and function.

SARS-CoV-2 does not infect the entire body in the same way, finds study

COVID-19, the disease caused by the pandemic coronavirus SARS-CoV-2, is primarily regarded as a respiratory infection. Yet the virus has also become known for affecting other parts of the body in ways not as well understood, sometimes with longer-term consequences, such as heart arrhythmia, fatigue and "brain fog."

Household odorant smell tests could help detect COVID-19, say study

Researchers at the Weizmann Institute of Science and other institutions developed a new tool to help detect COVID-19 infection. The team developed and tested a real-time tool to measure olfactory perception impairment by asking the participants to smell household odorants.

Basigin does not facilitate SARS-CoV-2 entry, say researchers

Researchers investigated the significance of a transmembrane glycoprotein basigin, or CD147, as a host cell co-receptor required for the entry of SARS-CoV-2. The findings reveal that recombinant human basigin does not interact with full-length spike protein or spike RBD of SARS-CoV-2.

UK and South African SARS-CoV-2 variants show higher binding affinity to host cell receptor

New research by a team of scientists at Stanford University School of Medicine in the U.S. found that both the UK and South African SARS-CoV-2 variants display tighter binding to the ACE2 receptor.

Researchers explore how N501Y mutation in SARS-CoV-2 increases viral transmissibility

Researchers at Erasmus University Medical Center in The Netherlands have explored how and why new variants of SARS-CoV-2 have exhibited heightened infectivity.

Corticosteroid receptor inhibitor shows anti-SARS-CoV-2 activity in vivo

A team of researchers examined PT150, which is an allosteric modulator of androgen and glucocorticoid receptors, to assess whether it had any antiviral activity or immunomodulatory activity to decrease the hyperinflammatory response of SARS-CoV-2 infection.

Two potent SARS-CoV-2 neutralizing antibodies effective against B.1.351 and B.1.1.7 variants

By analyzing the cryoEM structures of antibodies against the SARS-CoV-2 virus, researchers report that the neutralizing capabilities of two antibodies are not affected by new strains as these antibodies target regions of the virus away from the ACE2 binding regions.

Research predicts which mammal species can spread SARS-CoV-2

Scientists worldwide are fighting to contain the ongoing COVID-19 pandemic, which has already claimed more than 2.48 million lives. Preventing spillback infections is essential to containing the pandemic. To do so, it is vital to understand the nature of the virus, i.e., its susceptibility to a range of hosts.

Key mutation sites in the SARS-CoV-2 spike protein modulate antibody and ACE2 affinity

A paper recently uploaded to the preprint server bioRxiv by researchers at Chapman University in California (Feb 22nd, 2021) utilized computational methods to screen severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutants for affinity with the angiotensin-converting enzyme 2 (ACE2) receptor and monoclonal antibodies REG10987 and REG10933.

SARS-CoV-2 mutations allow escape from clinical monoclonal antibodies

A new research paper recently uploaded to the preprint server bioRxiv by Jesse D. Bloom et al. (22nd Feb 2021) aims to map all of the currently circulating SARS-CoV-2 lineages with resistance towards LY-CoV555 and LY-CoV016, and document the specific mutations that confer resistance, ultimately suggesting that future monoclonal antibody cocktails should target a more diverse range of epitopes.

Could laser-facilitated epicutaneous vaccination for SARS-CoV-2 be an alternative to intramuscular injection?

Scientists at the University of Salzburg and Pantec Biosolutions AG have developed a laser-facilitated epicutaneous immunization against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. The model has induced angiotensin-converting enzyme 2 (ACE2) blocking antibodies in mice.

How effective has Israel’s SARS-CoV-2 testing and vaccination campaign been against the UK variant?

A recent study by researchers at Tel Aviv University describes the UK variant’s rise to dominance in Israel. It also assesses the efficacy of the testing and vaccination programs employed by the government.

L452R mutation potentially favors adaptive evolution of SARS-CoV-2

A team of scientists from the United States recently investigated the mutational signatures in the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein.

23 Feb 2021

Could rotavirus vaccine platforms aid in the immunization campaign against SARS-CoV-2?

The study began with the generation of recombinant (r)SA11 rotaviruses, into which segment 7 modified RNAs were introduced. These encoded sequences for the non-structural protein NSP3 and some parts of the viral spike.

Cannabinoid receptor agonist shows potential protective effect on SARS-CoV-2-infected human heart cells

As scientists continue to search for effective antidotes to direct and indirect damage caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a new preprint research paper posted to the bioRxiv* server demonstrates the potential of cannabinoid receptor agonists to alleviate myocardial damage in this condition even in the absence of any inhibitory effect on viral infection as such.

WVU researchers set to identify SARS-CoV-2 variants, mitigate strain outbreaks

West Virginia University scientists knew it was coming. When health officials confirmed the first three cases of a COVID-19 variant in West Virginia late Friday (Feb. 19), they were not surprised.

22 Feb 2021

No evidence of SARS-CoV-2 fusing into the human genome

New data from researchers led by Majid Kazemian from Purdue University refutes claims from recent studies suggesting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could create a host-virus chimeric RNA. Their team found SARS-CoV-2 does not combine with the human genome.

22 Feb 2021

Researchers uncover 'hotspots' on the Spike protein that are critical for SARS-CoV-2 infection

The COVID-19 pandemic has prompted considerable investigation into how the SARS-CoV-2 Spike protein attaches to a human cell during the infection process, as this knowledge is useful in designing vaccines and therapeutics.
