Scientists compare ACE2 interaction with SARS-CoV-2 across species

Like other pathogenic coronaviruses, SARS-CoV-2 crossed the species barrier to cause human disease. This fact motivated the current study, published on the preprint server bioRxiv* in October 2020, which explores the way coronaviruses engage their host cell receptors in a range of animals.

Structure and mechanisms of ribosomal frameshifting during SARS-CoV-2 translation

The structure of a 3’ stimulatory pseudoknot in the viral genome or by itself has been proposed recently. Researchers report the structure and mechanisms of mammalian ribosomes during translation of the -1 frameshifting of the SARS-CoV-2 viral genome in a new study published on the preprint server bioRxiv.

Mathematical model for COVID-19 allows for dynamic social distancing and relaxation

Recently, researchers from York University, Toronto, Canada, presented a mathematical model for COVID-19 comprising groups of people with various levels of exposure to the disease based on data from Ontario, Canada. Their work is published on the preprint server medRxiv.

Furin cleavage site and D614G on SARS-CoV-2 spike evolved to balance infectivity, stability, cytopathicity

SARS-CoV-2 is the causative agent of COVID-19 disease, currently raging across the world. The virus has now infected more than 43.89 million individuals and claimed over 1.16 million lives. The study titled, "Spike glycoprotein and host cell determinants of SARS-CoV-2 entry and cytopathic effects," is released on the preprint server bioRxiv* in October 2020.

Gut's immune response to SARS-CoV-2 very different from the lung

Megan L. Stanifer et al. study the immune response in the human gut upon SARS-CoV-2 infection. The study published as a bioRxiv* preprint reveals a robust proinflammatory response: a cell type-specific or a tissue-specific regulation of interferon-mediated signaling during SARS-CoV-2 infection.

COVID vaccine misinformation lowering people's intent to get vaccinated

A new study by researchers at the Imperial College London and the London School of Hygiene and Tropical Medicine aimed to determine how online misinformation impacts COVID-19 vaccine uptake intent. Further, the team wanted to identify socioeconomic groups at a higher risk of not getting vaccinated and those who are most susceptible to online misinformation.

Bigger households associated with greater odds of SARS-CoV-2 transmission

Household transmission plays a pivotal role in the spread of SARS-CoV-2. The study recommends that it is essential for people to get tested immediately or as soon as symptoms appear. This way, they will take precautions to protect the other members of the family.

DNase coated melanin-like nanospheres for sepsis treatment in severe COVID

As the treatment of severe COVID-19 is very difficult, the researchers from the Korea Research Institute of Biosciences and Biotechnology (KRIBB) suggested that DNase-1 can be utilized to dissolve the neutrophil extracellular traps (NETs), hence halting the further progression of COVID-19.

Rapid CD169 assay for COVID-19 screening

Researchers in France have conducted a study demonstrating the sensitivity of a rapid flow cytometry assay that could be used to screen for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Research examines COVID-19 transmission patterns in Georgia, U.S.

Researchers from Emory University and the Georgia Department of Public Health have shown that the transmission of coronavirus disease 2019 (COVID-19) in the state of Georgia earlier this year changed over time and varied by age.

Important structures of SARS-CoV-2 PLpro protease

The pandemic of coronavirus disease 2019 (COVID-19) is changing the world like never before. This crisis is unlikely contained in the absence of effective therapeutics or vaccine.

Research on autophagy and coronavirus, implicates ULK1

Researchers from the University of British Columbia have discovered that the betacoronavirus-encoded papain-like protease disrupts autophagy, partly by targeting ULK1. Their work is reported on the preprint server bioRxiv* in October 2020.

27 Oct 2020

Lung biomarkers may predict severe COVID-19

Two University of New Mexico researchers postulate certain specific biomarkers' relevance in predicting the potential for progression to severe COVID-19 in a paper published on the preprint server bioRxiv*

SARS-CoV-2 is mainly spread in households and household-like settings

Ten months into the coronavirus disease (COVID-19) pandemic, health experts have a good understanding of how the virus spreads. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads through respiratory droplets and aerosols and enters the body through the mouth, nose, and eyes.

COVID-19 antibiotic risk factors

Now, a team of researchers at the University of Rochester Medical Center aimed to determine antibiotic prescribing rates and risk factors for antibiotic prescribing in hospitalized patients. They found that almost one-third of patients received more than one course of antibiotics.

10-24-year-olds are as susceptible to COVID-19 as older adults

In an attempt to replicate the results of previous studies, a team of researchers performed statistical analyses on COVID-19 prevalence data from the U.S. to compare the number of cases in adolescents and youth to that in older adults. Their work is published on the preprint server medRxiv.

New research on small non-coding RNAs and SARS-CoV-2

A recently published mini-review in the Frontiers in Microbiology on the altered expression of small non-coding RNAs during coronavirus-mediated infections.

Researchers generate a transcriptomic map of the COVID brain

COVID-19 is known to be associated with multiple changes in gene expression, but many of these are also seen in chronic brain conditions as well as in some abnormal mental conditions. A recent study published on the preprint server bioRxiv in October 2020 uncovers the molecular basis of this association.

New peptide derivatives that target the SARS-CoV-2 spike protein

In a new study published in the journal Cellular and Molecular Bioengineering, researchers report peptide derivatives, or peptidomimetics, based on the circle residues involved in the interaction of the spike protein and ACE2.
