Stabilized prefusion spike vaccine candidate induces powerful immune response

A new research paper by scientists at Janssen Vaccines & Prevention BV, in the Netherlands and published on the preprint server bioRxiv* is based on the assumption that an effective vaccine against these infections will induce neutralizing antibodies and an immune response favoring Th1 immunity.

SARS-CoV-2 spike protein recognized by innate immune receptors in a glycan-dependent way

The spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) depends on its ability to infect new host cells following its replication and release from infected cells. This pivots on its ability to bind to cell surface receptors like the ACE2 enzyme.

NIH invests $248.7 million in new COVID-19 testing technologies to meet U.S. demand

The National Institutes of Health is investing $248.7 million in new technologies to address challenges associated with COVID-19 testing (which detects SARS-CoV-2 coronavirus).

War of sugars - estrogen provides protection in COVID-19

Now a new study published on the preprint server bioRxiv in July 2020 reports that sex hormones could affect the function of the fusion protein that is dependent upon the human ACE2 receptor, thus preventing the entry of the virus into the host cell.

Emergent SARS-CoV-2 D614G spike mutation more infective due to "open" morphology

Researchers from the Los Alamos National Laboratory and Duke Human Vaccine Institute & Department of Surgery demonstrated that globally prevalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with the amino acid substitution D614G in the spike protein is much more infective due to profitable binding encounters with the host receptors.

Population screening has potential to identify individuals at risk for inherited genetic conditions

In a new study published today in the journal Nature Medicine, researchers behind the Healthy Nevada Project® suggest that community-based genetic screening has the potential to efficiently identify individuals who may be at increased risk for three common inherited genetic conditions known to cause several forms of cancer and increased risk for heart disease or stroke.

Analysis of the SARS-CoV-2 proteome via visual tools

Now, a new study published on the preprint server bioRxiv* in July 2020 shows how this can be advanced at a greater speed by combining experimental results with homology models obtained by high-throughput pipelines. This will help produce new hypotheses that will show novel druggable targets for effective drug development.

Researchers visualize DNA G-quadruplex formation in live cells for the first time

The formation of four-stranded DNA has been tracked in living human cells, allowing scientists to see how it works, and its possible role in cancer.

Researchers stabilize the closed SARS-CoV-2 spike trimer

Now, a new study by researchers at Janssen Vaccines & Prevention BV and Leiden University and published on the preprint server bioRxiv uses cryoEM to reveal the structure of this trimer, in order to support both vaccine development and diagnostic testing based on antibody production.

NUS teams develop three nasopharyngeal swab designs for COVID-19 testing

Since the outbreak of COVID-19, there has been a global surge in demand for nasopharyngeal (NP) swabs, a key element in testing for SARS-CoV-2. Singapore is no exception. Commercially available NP swabs used in COVID-19 test kits are often out of stock due to supply chain disruptions.

Research shows how SARS-CoV-2 alters translation

Now, a new study published on the preprint server bioRxiv in July 2020 shows that the 5’ end of the RNA molecule is capable of inhibiting the binding of mRNA to the ribosomal 40S subunit, thus preventing translation.

9 Jul 2020

Spike proteins of SARS-CoV-2 covered by mobile glycans that shield its surface

A new study of the structural dynamics of the SARS-CoV-2 spike protein published in the preprint server bioRxiv in July 2020 reports on the epitopes that could be possible immune targets for the development of vaccines.

New study comprehensively profiles environmental factors linked to childhood obesity

Childhood obesity is a health threat that is becoming more and more common worldwide. It increases risk later on for a variety of life-threatening challenges, including type 2 diabetes, cancer, heart disease, and even mental health problems.

Air pollution, smoking and built environment may play a role in childhood obesity

How do environmental exposures during pregnancy and childhood influence the risk of obesity in children? The Barcelona Institute for Global Health, a center supported by the "la Caixa" Foundation, and the University of Southern California led the first major study to investigate the associations between many pollutants and environmental factors --77 prenatal and 96 childhood exposures-- and the risk of childhood obesity.

Direct structural link between SARS-CoV-2 and essential fatty acid

Now, a new study published on the preprint server bioRxiv in June 2020 reports the discovery of a novel free fatty acid (FFA) binding pocket on the SARS-CoV-2 virus that could explain in part the viral effects of hyperinflammation, immune modulation, and membrane structure.

How antibodies neutralize SARS-CoV-2 in convalescent patients

A new study by researchers from the United Kingdom and Taiwan and published on the preprint server bioRxiv in June 2020 describes the structural basis for the neutralizing effect of the SARS-CoV-2 antibody on the virus. This also indicates a possible therapeutic molecule by identifying its binding epitope as possibly a major neutralizing site.
