Genetic variants of human ACE2 are differentially recognized by SARS-CoV-2

Scientists at the University of Wisconsin reveals that the genetic variants of human angiotensin 2 (ACE2) receptors can have altered recognition by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the coronavirus disease 2019 (COVID-19) pandemic. The study is currently available on the bioRxiv* preprint server.

Study invalidates Ebselen and other broad-spectrum SARS-CoV-2 Mpro inhibitors

Other novel compounds with Mpro inhibitory activity have also been claimed to have antiviral activity. These include ebselen, disulfiram, tideglusib, carmofur, shikonin, and PX-12. A new research paper discusses the role of these molecules as potential Mpro inhibitors in the prevention of SARS-CoV-2 infection.

Animal data supports efficacy of baricitinib vs SARS-COV-2

The high burden of disease caused by the COVID-19 pandemic has led to much research on effective ways to mitigate the health, social, and economic impact of the spread of the infection. A recent study published on the preprint server bioRxiv* in September 2020 reports on the characteristics of the drug baricitinib when used as monotherapy to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

T cells on the front line of COVID-19 response

In the new study, published in the journal Cell, the team has found that the uncoordinated responses produced by the immune system, especially in people who are more than 65 years old, maybe the reason why older adults are more at risk.

Wearing eyeglasses protects against SARS-CoV-2

A team of scientists from China suggests that people who wear eyeglasses for more than 8 hours a day may be less susceptible to infection by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study is published recently in the journal JAMA Ophthalmology.

New drug candidate suppresses SARS-CoV-2 replication

Researchers at Stanford University and Utah State University have developed a novel inhibitor of the coronavirus main protease (Mpro) that effectively suppresses the viral replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Could pineapples be a new weapon against COVID-19?

Results of a recent research endeavor from the United States indicate that bromelain or bromelain rich pineapple stem may be utilized as an antiviral agent against coronavirus disease (COVID-19), but also for potential future coronavirus outbreaks. This exciting paper is currently available on the bioRxiv preprint server.

LOX-1-immature neutrophils may help identify COVID-19 patients at risk of thrombosis complication

To predict severe outcome in COVID-19 patients, innate immune cellular signals are analyzed, identifying two novel neutrophil subsets: LOX-1- and CD123-expressing CD10-CD64+. Thromboembolic events correlated with high LOX-1 immature neutrophils – a potential prognostic signature.

COVID-19 could be diagnosed using stroke scans

New research from King's College London has found that COVID-19 may be diagnosed on the same emergency scans intended to diagnose stroke.

Testing settled solids in sewage for SARS-CoV-2 more sensitive approach than testing influent

Many studies on the containment of the ongoing COVID-19 pandemic have dealt with the possible role of wastewater in predicting and detecting future outbreaks and understanding the epidemiology of COVID-19 disease. A recent study published on the preprint server medRxiv* in September 2020 shows that solid waste in sewage is a better substrate for testing than influent.

Ceftazidime flagged as a potential inhibitor of the SARS-COV-2 virus

After screening more than 3,500 FDA-approved drugs and small molecules, researchers at the Chinese Academy of Sciences found that ceftazidime, an antibiotic approved for use in treating pneumonia, binds to the receptors that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to in human cells.

Optimal antibody combinations and Fc binding inhibit SARS-CoV-2 in vivo

A recent study by researchers at the University of North Carolina at Chapel Hill and The Rockefeller University and published on the preprint server bioRxiv in September 2020 shows that a combination of neutralizing antibodies with intact Fc effector function can effectively reduce the viral load and prevent infection.

Seropositive partners increase risk of COVID-19 but not obstetric complications in pregnant women

While earlier studies have shown the significance of serological testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pregnant women, their partners have largely been excluded. Now, a new Danish study published on the preprint server medRxiv in September 2020 reports the impact of serologic testing in both pregnant women and their partners, as well as their newborns.
