Study identifies three novel broad-spectrum SARS-CoV-2 cell entry inhibitors

Researchers from the National Institutes of Health (NIH) and Cornell University in the U.S. just described several new inhibitors of human coronavirus spike proteins by screening a library of approved drugs with SARS-S and MERS-S pseudotyped particle entry assays. Their exciting findings are currently available on the bioRxiv preprint server.

Researchers discover marine alga from Kiel Fjord as potential remedy against infections, skin cancer

Healing with the help of marine organisms is no utopia. Already 12 life-saving drugs, e.g. against cancer, have been developed from marine organisms and their symbiotic microbiota.

New platform prioritizes synergistic drug combinations against SARS-CoV-2

Researchers in the U.S. have used a new web-based platform to help identify synergistic and antagonistic drug combinations and their underlying mechanisms of action in the context of coronavirus disease 2019 (COVID-19).

SARS-CoV-2 infection modeling in iPSC-derived type 2 cells

The most fatal form of COVID-19 disease is acute respiratory distress syndrome (ARDS), caused by direct viral injury as well as indirect noxious effects caused by cytotoxic chemicals and inflammatory processes. A new study published on the preprint server bioRxiv* in June 2020 shows that this is partly due to the rapid onset of inflammation caused by the infection of type 2 alveolar cells with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Immune response variations across the COVID-19 spectrum

A new study published on the preprint server medRxiv in June 2020 describes differences in the adaptive and innate immune response in mild, moderate, and severe COVID-19. This may mean that permanent immune responses occur only in patients who recover from severe COVID-19.

SARS-CoV-2 induces broad T cell response in recovering patients

A new study published on the preprint server bioRxiv in June 2020 shows that T cell responses in COVID-19 patients are broader and more robust in severe disease and are explicitly directed against spike, memory, and ORF3a proteins.

Balanced B and T cell response required to control SARS-CoV-2

A new study by researchers in the Netherlands and published on the preprint server bioRxiv in June 2020 describes the differences in T and B cell responses seen in patients with severe COVID-19.

Nanofiber face masks maintain filtration efficiency after washing

With the global spread of coronavirus infections, personal protective equipments especially hygeine face masks are receiving much attention. Masks are essential items for the primary protection of the respiratory tract from viruses and bacteria that are transmitted through the air as droplets.

Low potassium levels in COVID-19 disease

Now a new study by an Italian team of researchers published in June 2020 on the preprint server medRxiv reports that potassium levels are often low in COVID-19 disease, mostly due to the urinary loss of potassium.

Anti-RBD antibodies shown to neutralize active SARS-CoV-2

A new study published on the preprint server bioRxiv* in June 2020 reports the discovery of multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in samples from healthy donors, collected before the pandemic. These antibodies are capable of inhibiting the binding of the spike protein of the virus to the angiotensin-converting enzyme 2 (ACE2) molecule and can neutralize active infection of cells in culture.

SARS-CoV-2 can adversely affect cardiac cells and heart function

A research group from Germany demonstrated a direct toxic effect of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on cardiac cells in their paper published on the bioRxiv* preprint server. The finding warrants an in-depth analysis of cardiac tissue in certain coronavirus disease (COVID-19) patients, as well as close monitoring for any direct cardiomyocyte injury.
