Monocytes could be critical in dysregulated immunity in COVID-19

A new study by Spanish researchers as part of the GEN-COVID Project, and published on the preprint server medRxiv* in June 2020, suggests that monocytes are primarily involved in triggering the hyperinflammatory immune response that may underlie severe COVID-19 infection.

The receptor binding domain of the SARS-CoV-2

With the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) across most of the world, scientists are working strenuously to find effective therapies or vaccines. Most strategies being worked on at present are targeting viral entry into the host cells, mainly through the interaction of the SARS-CoV-2 S protein with the angiotensin-converting enzyme 2 (ACE2) receptor.

Inhibition of coronavirus spike protein binding to ACE2

A novel coronavirus, CoV-19, and a later phenotype CoV-2 were identified as the primary cause for severe acute respiratory syndrome (SARS CoV-2). The spike (S) protein of CoV-2 is one target for the development of a vaccine to prevent the viral entry into human cells. The inhibition of the direct interaction between ACE2 and the S-protein could provides a suitable strategy to prevent the membrane fusion of CoV-2 and the viral entry into human cells. Using MD simulations, we investigate the assembly process of a Coronavirus Spike protein fragment, the hexapeptide YKYRYL on the ACE2 receptor and its inhibitzory effect on the aggregation and activation of the CoV-2 spike receptor protein at the same receptor protein.

SARS-CoV-2 genome variants in India

A new study published online on the preprint server bioRxiv in June 2020 surveys the genetic diversity of SARS-CoV-2 strains in India.

SARS-CoV-2 invasion of central nervous system through olfactory tract

As the COVID-19 pandemic continues to claim lives throughout the world, the evidence is mounting that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects the respiratory tract as well as the central nervous system. Now, a new study by German researchers published on the preprint server bioRxiv in June 2020 describes various neurological manifestations of COVID-19, as well as the underlying pathophysiology.

Tocilizumab in COVID-19 patients on mechanical ventilation

Now, a new study by researchers from the University of Michigan and published on the online preprint server medRxiv* in June 2020 shows that the cytokine inhibitor tocilizumab could have a favorable effect on survival in the most severely infected patients who require mechanical ventilation. This needs to be confirmed by clinical trials.

New strategy may facilitate development of multi-epitope peptide vaccine against SARS-CoV-2

By combining T and B lymphocyte analysis with manufacturability heuristic, researchers from the US and Germany proposed a set of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine peptides to use in subsequent animal studies and clinical trials. Their paper is currently available on the bioRxiv preprint server.

Kidney enzyme renalase a potential therapy for severe COVID-19

Researchers from Yale School of Medicine have discovered that a low blood level of an enzyme called renalase is associated with severe coronavirus disease 2019 (COVID-19).

Zinc-finger antiviral protein makes SARS-CoV-2 highly susceptible to interferons

By looking into zinc-finger antiviral proteins (ZAP), a new study from Germany and the United Kingdom (UK) and available on the preprint server bioRxiv suggests that zoonotic transmission of a coronavirus with a specific genetic make-up facilitated the pandemic spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but also its sensitivity to interferons.

Lockdown adversities could affect sleep and mental health

Researchers at University College London warn that the adversities people are facing in the UK as a result of lockdown during the coronavirus disease 2019 (COVID-19) pandemic may be causing sleep problems that could affect mental health.

People suffering from rheumatoid arthritis with increased disease activity have high thrombosis risk

People suffering from rheumatoid arthritis with increased disease activity are more often affected by thrombosis.

Approved drug could help dampen massive immune response associated with severe COVID-19

The drug acalabrutinib, FDA-approved for the treatment of several types of B cell cancers, improved the oxygenation levels and decreased molecular markers of inflammation in a majority of 19 patients hospitalized for the treatment of severe COVID-19, according to a new study by Mark Roschewski and colleagues.

High mortality rates among coronavirus-positive dialysis patients

Spain is one of the European countries besides the UK and Italy that was particularly hard hit by the coronavirus pandemic in March.

Bystander CPR benefits outweigh the risks of COVID-19 infection

Analysis of Seattle emergency medical services and hospital data from January 1 to April 15, 2020, indicates bystander CPR is a lifesaving endeavor whose benefits outweigh the risks of COVID-19 infection, according to a new article published yesterday in the American Heart Association's flagship journal Circulation.

Kidney impairment significantly higher among hospitalized COVID-19 patients

Germany was not hit as hard by the SARS-CoV-2 pandemic as many other European countries. The reason for this is that the wave of infection reached Germany later, that the authorities were warned by the situation in Italy and Spain and at an early stage ordered a lockdown and conducted extensive testing.

New analytical tool uses air travel data to predict COVID-19 spread

As the COVID-19 pandemic enters a new phase, punctuated by emerging hot spots and continuing global spread, a new analytical tool developed by RAND Corporation researchers allows policymakers to predict regional risks of importing cases of COVID-19.

Tear-gassing protesters during an infectious outbreak ‘a recipe for disaster’

In nationwide demonstrations sparked by the killing of George Floyd in police custody, protesters have been frequently pepper-sprayed or enveloped in clouds of tear gas.

New guidance for healthcare providers caring for hospitalized COVID-19 patients with diabetes

The COVID-19 pandemic presents new challenges for clinicians caring for infected patients with diabetes, according to new guidance published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Sleep fragmentation associated with inflammation and atherosclerosis

Disrupted nightly sleep and clogged arteries tend to sneak up on us as we age. And while both disorders may seem unrelated, a new study from the University of California, Berkeley, helps explain why they are, in fact, pathologically intertwined.

New approach helps identify protein biomarkers in the blood of COVID-19 patients

People respond very differently to infection with the novel coronavirus (SARS-CoV-2). While some patients develop no symptoms at all, others will develop severe disease and may even die. For this reason, there is an urgent need for 'biomarkers', quantifiable biological characteristics which could provide a reliable means of predicting disease progression and severity.
