Developing orally administrable drugs to combat SARS-CoV-2

Researchers in China have reported the successful design and synthesis of two antiviral compounds that target the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)’s main protease, essential in virus replication.

Single Sputnik V vaccine dose elicits robust immune response in previously infected individuals

A new preprint research paper posted to the medRxiv server describes successful immunization of the vaccinated population with a single dose of the Russian-made Sputnik V vaccine.

Linear epitope mapping of the SARS-CoV-2 spike protein

The spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the primary target of many drug discovery efforts and is similarly utilized in each of the approved COVID-19 vaccines to elicit the generation of anti-spike protein antibodies, thereby granting immunity.

Antibody agents effective at neutralizing European, South African, and United States SARS-CoV-2 variants

Researchers in the United States have demonstrated the effectiveness of three antibody agents at neutralizing recently emerged variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) pandemic.

New screening method detects cancer biomarkers more effectively

Early screening can mean the difference between life and death in a cancer and disease diagnosis. That's why University of Central Florida researchers are working to develop a new screening technique that's more than 300 times as effective at detecting a biomarker for diseases like cancer than current methods.

Identification of specific anti-SARS-CoV-2 antibodies with cross-neutralization potency

A team of scientists from the USA and Canada recently characterized the cross-neutralizing potency of anti-SARS-CoV-2 antibodies isolated from COVID-19 patients. The findings reveal that some of the isolated antibodies targeting the spike RBD and the S2 subunit are capable of cross-neutralizing other members of the human beta-coronavirus family.

Researchers examine SARS-CoV-2 RNA interactome

A new study focuses on the identification of RNA-binding protein by mass spectrometry (ChIRP-M/S) approach. This study develops a global map that contains the complete set of host proteins that involve the SARS-CoV-2 genome during infection. This study has successfully identified new SARS-CoV-2 host dependency factors by merging proteomics data with gene silencing experiments. Such a discovery has paved new roads to develop more antiviral therapies.

New study shows large within- and between-assay variation for ß-CTX measurement

A new study by the IFCC‑IOF Committee for Bone Metabolism shows large within- and between-assay variation for ß-CTX measurement; until harmonization is achieved, proposes measuring ß-CTX by the same assay on EDTA plasma, especially for research.

Alzheimer’s symptoms linked to COVID-induced brain injury

New research shows further evidence between COVID-19 infection and the development of long-term neurological symptoms. The findings found COVID-induced neuroinflammation and microvascular injury contributed to dementia-like symptoms. However, they also found evidence indicating a low possibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) directly invading the brain.

Fluoxetine (Prozac) performs strongly in vitro against SARS-CoV-2 (including mutants)

Researchers from Finland, to expand on these studies, tested some of these drugs against the new SARS-CoV-2 variants. The study is published on the preprint server bioRxiv.

Increased replicative fitness of SARS-CoV-2 UK strain in human bronchial cells

A recent study from France showed that the UK variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – also known as B.1.1.7 variant – can replicate much more efficiently in a reconstituted human bronchial epithelium, which may explain why it spreads so rapidly in the human population. The study is currently freely available on the bioRxiv preprint server.

Researchers examine acriflavine's antiviral potential against SARS-CoV-2

Acriflavine is traditionally employed as a topical antiseptic, though has more recently been implicated as an antiviral agent at low doses, potentially by stimulating the production of interferon. In a new study recently uploaded to the bioRxiv* preprint server, the application of the drug to SARS-CoV-2 infection is investigated, demonstrating a broad activity towards a range of other betacoronaviruses.

24 Mar 2021

Researchers develop innovative biosensor that can detect and quantitate SARS-CoV-2 infection

Researchers have generated protease-activatable fluorescent and luminescent biosensors for SARS-CoV-2 MPro (main protease) and PLPro (papain-like protease) activity, one based on “flip” GFP (FlipGFP), and the other based on circularly permuted firefly luciferase (FFluc).

High throughput screening for COVID-19 with the VOYAGER pipette

The COVID-19 pandemic has slowed down research in many scientific areas, but for the Jain Lab in the Department of Chemical Engineering at the University of Florida, the pandemic has created an exciting opportunity to repurpose their work.

Research suggests toothpaste and mouthwash ingredients could help prevent SARS-CoV-2 infection

Now, new research published on the bioRxiv preprint server focuses on the effect of some typical ingredients present in commercially available mouthwashes and toothpaste on the mechanisms of SARS-CoV-2 entry into host cells.

24 Mar 2021

Study shows single dose of mRNA vaccine may suffice for those with prior SARS-CoV-2 infection

A recent study by researchers from Philadelphia, currently available on the medRxiv preprint server, shows that individuals with prior infection caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibit substantial immune memory and develop a robust response to the first dose of an mRNA vaccine.

23 Mar 2021

Correlation of antibody titers with COVID-19 vaccine efficacy

In a new study the relationship between virus-neutralizing antibody and spike protein-binding IgG antibody levels is explored following vaccination by one of seven currently deployed vaccines. The findings support the use of antibody titers as correlates of protection for COVID-19 vaccines.

Immunoassay heterogeneity and implications for SARS-CoV-2 serosurveillance

In a recent study, scientists have quantified anti-SARS-CoV-2 antibody levels up to 9 months after infection.
