SARS-CoV-2 spike stimulates hyperinflammation via Toll-like receptor 2

A new study, released on the bioRxiv* preprint server, describes the mechanism of inflammation in severe COVID-19, besides revealing a potential new therapeutic target to modulate the severity of COVID-19.

DNA spike-ins increase reliability of amplicon-based sequencing of SARS-CoV-2 genomes

In the interests of cost-effectiveness and rapidity, amplicon-based sequencing of the viral genome has been used to provide a sensitive means of genomic surveillance. A new preprint, which was released on the bioRxiv* server, shows how this can be tweaked to make it a reliable source of genomic data by reducing the known potential for contamination.

Diagnostic test helps identify the virulent forms of swine bacterial pathogens

A team led by researchers in Penn State's College of Agricultural Sciences has developed a diagnostic test that can identify virulent forms of the swine bacterial pathogen Streptococcus equi subspecies zooepidemicus -- often referred to as "Strep zoo" -- which can cause severe illness and death in pigs, other animals and rarely people.

New drug regimen is safe and effective in children with cystic fibrosis

An international, open-label Phase 3 study, co-led by Susanna McColley, MD, from Ann & Robert H. Lurie Children's Hospital of Chicago, found that a regimen of three drugs (elexacaftor/tezacaftor/ivacaftor) that targets the genetic cause of cystic fibrosis was safe and effective in 6-11-year-olds with at least one copy of F508del mutation in the CFTR gene, which is estimated to represent almost 90 percent of the cystic fibrosis population in the United States.

Rare pulmonary disease discovered in rural Alberta

A rare pulmonary disease that is linked to bats has made Alberta home, according to new research led by provincial lab scientists.

Mass vaccination needed to protect against future resurgences of COVID-19

The first long-term seroprevalence study of residents in Wuhan, China, has found that 6.9% of people in the city had antibodies against COVID-19 in April 2020, and 82% of these people had an asymptomatic infection.

Study shows how ACE2 mutations influence SARS-CoV-2 spike binding in humans and animals

Researchers at the University of Wisconsin–Madison aimed to better understand how SARS-CoV-2 interacts with various mammalian angiotensin-converting enzyme 2 (ACE2) receptors. This way, they can identify the factors that influence intra- and cross-species virus transmission.

Engineering immunogens to focus immune response to SARS-CoV-2

Researchers have designed constructs by adding more glycans and adding the receptor-binding motif from related sarbecoviruses to focus the immune response to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding motif. Such immunogens could potentially also neutralize other variants and coronaviruses.

Identifying druggable targets on an essential SARS-CoV-2 protein

In a research paper recently uploaded to the preprint server bioRxiv by Newman et al. (March 15th, 2021) the structure and role of one such protein: NSP13, is investigated, with two appealingly druggable targets being identified, possibly opening a new route towards a novel SARS-CoV-2 antiviral agent.

Fighting SARS-CoV-2 with materials science

In a recent editorial in the journal Emergent Materials, Dr. Huseyin C. Yalcin from Qatar University Biomedical Research Center and Dr. Ajeet Kaushik from Florida Polytechnic University announce several important developments in their timely special issue entitled “Materials Science in the Battle against COVID-19”.

UK SARS-CoV-2 variant 40% more transmissible than previous strains

Researchers in Japan have estimated that the B.1.1.7 strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that recently emerged in England is 40% more transmissible than strains previously circulating in the country.

SARS-CoV-2 vaccination should be carefully targeted towards certain groups, say researchers

Researchers in the UK have provided important insights into the impact that vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – may have on infection rates, disease prevalence and immune escape by the virus.

Scientists explore structure of SARS-CoV-2 receptor-binding domain with G485R mutation

Researchers at the Bio21 Institute and Department of Biochemistry and Pharmacology, The University of Melbourne, studied the structure of a SARS-CoV-2 spike receptor-binding domain (RBD) with a G485R mutation. This mutation is a residue and not directly involved in interactions with the angiotensin-converting enzyme 2 (ACE2) residues but found in the Β1´/Β2' loop region.

New study maps SARS-CoV-2 and host protein interactions in detail

A new study has developed a systemic map detailing the mechanistic interactions and disruptions between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its host cell.

SARS-CoV-2 variants with E484K mutation show mRNA vaccine-induced antibody evasion

A recent study found that the Pfizer-BioNTech mRNA vaccine had limited efficacy in identifying mutated receptor-binding domains (RBDs) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein similar to the B.1.351 and P.1 variants.
