RUDN geneticist finds a bifidobacterial protein that can reduce inflammation in COVID-19

A geneticist from RUDN University studied the effect of Bifidobacterium (intestinal bacteria) on the inflammatory process and discovered that their surface protein is capable of stopping excessive or uncontrollable inflammation, like the one observed in COVID-19 patients.

Circadian rhythm affects SARS-CoV-2 infection and host immune response

In an interesting bioRxiv preprint paper, French researchers show that the time day can affect infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as guide subsequent host immune response – implying that circadian rhythm may well be a novel target for managing viral progression.

Computational models screen for coronaviruses likely to infect humans

The researchers from Rochester Institute of Technology and the Hauptmann-Woodward Medical Research Institute produced models of the receptor-binding domain (RBD) found on outbreak strains of betacoronaviruses and its interaction with the host cell receptor angiotensin-converting enzyme 2 (ACE2).

Sticky DNA webs may cause tissue damage associated with severe COVID-19 infections

Sticky webs of DNA released from immune cells known as neutrophils may cause much of the tissue damage associated with severe COVID-19 infections, according to two new studies published September 14 in the Journal of Experimental Medicine.

Single-molecule imaging of SARS-CoV-2 spikes on virus particles

Using single-molecule FRET analysis, a team of researchers has revealed how the different conformations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein are interconnected. Figuring out the different conformations in real-time and which conformations antibodies prefer may help design effective vaccines and drugs. The research is published on the preprint server bioRxiv*.

Researchers identify the missing link in the production of nitric oxide

Some microorganisms, the so-called methanotrophs, make a living by oxidizing methane (CH4) to carbon dioxide (CO2). Ammonia (NH3) is structurally very similar to methane, thus methanotrophs also co-metabolize ammonia and produce nitrite.

New insights into structural stability of SARS-CoV-2 main protease

In a recent bioRxiv preprint paper, researchers from the US and Italy utilized molecular dynamics simulations and revealed that the conformational stability of the SARS-CoV-2 binding site, bound inhibitors, and the hydrogen bond networks of the viral main protease (Mpro) are highly sensitive to protonation assignments.

A map of SARS-CoV-2 escape mutations enables the development of therapeutic antibody cocktails

A recent tour-de-force study by the US researchers describes a comprehensive approach to completely map mutations to the SARS-CoV-2 receptor-binding domain (RBD) that escape antibody binding – enabling, in turn, rational design of antibody therapeutics and appraisal of the antigenic consequences of viral evolution. The results are currently available in a bioRxiv preprint paper.

Study uncovers the locus of male sexual desire in the brain

The locus of male sexual desire has been uncovered in specific regions of brain tissue where a key gene named aromatase is present, reports a new Northwestern Medicine study in mice.

Yale researchers identify possible treatment for Duchenne muscular dystrophy

Researchers at Yale have identified a possible treatment for Duchenne muscular dystrophy (DMD), a rare genetic disease for which there is currently no cure or treatment, by targeting an enzyme that had been considered "undruggable."

Researchers develop highly scalable, accurate antibody test for COVID-19

An antibody test for the virus that causes COVID-19, developed by researchers at The University of Texas at Austin in collaboration with Houston Methodist and other institutions, is more accurate and can handle a much larger number of donor samples at lower overall cost than standard antibody tests currently in use.

Maternal psychological wellbeing during pregnancy has a positive effect on newborns

A group of researchers from Charité - Universitätsmedizin Berlin have been able to show that maternal psychological wellbeing during pregnancy has a positive effect on newborn infants.

Study sheds light on the disproportionate impact of COVID-19 on Blacks

In a study published in JAMA today, Mount Sinai researchers report findings that shed some light on the disproportionate impact of COVID-19 on Blacks, who have experienced rates of infection and death that are much greater, in some areas twice and three times more, than their proportion of the population.

Effective, simple, safe self-amplifying RNA vaccines

A recent review paper in the journal Current Opinion in Virology in September 2020 shows how a new generation of RNA vaccines called self-amplifying RNA vaccines are more potent than conventional mRNA vaccines and could hold the key to the global production of cost-effective potent COVID-19 vaccines.

New study brings researchers closer to a universal COVID-19 antibody test

A new study released by Houston Methodist takes researchers a significant step closer to developing a uniform, universal COVID-19 antibody test.

Researchers explore IgA response to SARS-CoV-2

A new study published on the preprint server bioRxiv* and conducted by researchers from The Rockefeller University in New York examined the role of IgA antibodies in preventing SARS-CoV-2 infection. In this study, the team analyzed the IgA response to SARS-CoV-2 infection in 149 individuals.

Researchers say Influenza may increase risk of COVID-19

A recent study by researchers suggests that the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is influenced by influenza virus infection during the initial period of coronavirus disease 2019 (COVID-19) pandemic in Europe. The study is currently available on the medRxiv preprint server.
