New serological test for COVID-19 helps determine herd immunity, vaccine efficacy

New COVID-19 test evaluates herd immunity and vaccine efficacy with high accuracy.

Avidity of binding responsible for cross-neutralization of SARS-CoV-1 and SARS-CoV-2

In a new study published on the preprint server bioRxiv researchers characterized the crystal structure of the antibody-SARS-CoV-2 RBD complex in an attempt to find the epitope and the mechanism that enables cross-neutralization.

Embryos are susceptible to COVID-19 if mothers get sick, indicates study

Genes that are thought to play a role in how the SARS-CoV-2 virus infects our cells have been found to be active in embryos as early as during the second week of pregnancy, say scientists at the University of Cambridge and the California Institute of Technology (Caltech).

Regeneron's COVID-19 antibody-drug cocktail treats SARS-CoV-2 virus in animals

Now, Regeneron Pharmaceuticals says its COVID-19 antibody-drug cocktail under development prevented and treated the disease in monkeys and hamsters, showing promise that it may work in humans.

Study: "Memory" T cells that recognize common cold coronaviruses also recognize SARS-CoV-2

Your immune system's "memory" T cells keep track of the viruses they have seen before. This immune cell memory gives the cells a headstart in recognizing and fighting off repeat invaders.

Picomolar inhibitors to SARS-CoV-2 proteins

Now, a new study published on the preprint server bioRxiv in August 2020 reports the development of mini-inhibitors based on computational design, that are suitable for such topical use.

Novel mutation identified in SARS-CoV-2 spike protein from Sweden

Researchers from Sweden and Brazil have identified a novel mutation in a strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient in Stockholm, Sweden, in late April.

4 Aug 2020

Regeneron antibody cocktail shows promise as potential COVID-19 treatment

Researchers in the U.S. have shown both preventive and treatment effects of an antibody cocktail in animal models of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - the agent that causes coronavirus disease 2019 (COVID-19).

Study shows high SARS-CoV-2 seroprevalence, but low death rate in Malawi's health care workers

A study by researchers from Malawi and United Kingdom reveals a significant discrepancy between predicted coronavirus disease (COVID-19) mortality in the observed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence rates in health care workers and reported deaths in urban Malawi in southeastern Africa, indicating early exposure, but a slow progression of the outbreak. Their findings are currently available on the medRxiv preprint server.

SARS-CoV-2 lured away and trapped by a new decoy version of ACE2

Researchers in the United States and Canada have engineered affinity-optimized “receptor traps” that prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from binding to and infecting cells.

3 Aug 2020

Novel short ACE2 isoform may influence SARS-CoV-2 susceptibility

A study led by researchers at the University of Southampton, UK, has identified a novel short isoform of the full-length receptor that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses to gain entry to host cells.

3 Aug 2020

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.

3 Aug 2020

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.

3 Aug 2020

New bivalent vaccine delivers robust cell-mediated and humoral immunity against SARS-CoV-2

In a groundbreaking bioRxiv study, US researchers demonstrate the capability of next-generation bivalent human adenovirus serotype 5 (hAd5) vaccine for inducing both cellular and humoral immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – using both an S protein sequence optimized for cell surface expression and a conserved nucleocapsid antigen designed to be transported to the endosomal subcellular compartment.

COVID-19 rapid antibody test receives CE mark and mass production begins

The COVID-19 rapid antibody test, developed by Abingdon Health, the medical device manufacturer leading the UK-Rapid Test Consortium, has received its CE mark. This means it is approved for professional use in the UK and EU.

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.

Researcher uses in silico analysis of SARS-CoV-2 spike protein to fast-track passive immunity

With millions of COVID-19 cases reported across the globe, people are turning to antibody tests to find out whether they have been exposed to the coronavirus that causes the disease. But what are antibodies? Why are they important? If we have them, are we immune to COVID-19? And if not, why not?
