Platelets may be contributing to COVID-19

The current pandemic of COVID-19 is characterized mainly by severe acute respiratory distress of the lungs, but other organ dysfunctions are also being observed, including the heart and blood vessels. Now, a new paper published on the preprint server medRxiv* in June 2020 describes the abnormal activation of platelets in this disease and the link between this phenomenon and poor outcomes for COVID-19 patients.

New assay rapidly tests SARS-CoV-2 neutralization and screens antivirals

Researchers at the University of Texas Medical Branch, Galveston, have developed a new platform that can rapidly test neutralizing antibody activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and perform high-throughput screening of potential antiviral agents.

Effective neutralization of SARS-CoV-2 by synthetic nanobodies targeting the spike protein

In their recent bioRxiv paper, a multinational group of researchers reported rapid isolation and characterization of nanobodies from a synthetic library (known as sybodies) that target the receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein – with a strikingly high neutralization ability.

ACE inhibition in kidney could influence pathogenesis of SARS-CoV-2

The dynamics of angiotensin-converting enzyme 2 (ACE2) expression in the kidney could have implications for the infectivity and pathogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), say researchers.

Structured 'cut-and-paste' design enables streamlined development of SARS-CoV-2 molecular probes

A seminal study by US researchers, currently available on the bioRxiv* preprint server, demonstrates how structure-based design can be efficiently employed to develop molecular probes targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike and its domains, with possible future use in diagnostics, treatment and vaccine development.

Statin therapy linked to lower death rate in hospitalized patients with COVID-19

The use of cholesterol-lowering drugs called statins is associated with a lower death rate and a lower incidence of mechanical ventilation in patients hospitalized with Coronavirus disease 2019 (COVID-19), researchers report June 24 in Cell Metabolism.

Abnormal findings in testicular tissue of COVID-19 patients, SARS-CoV-2 mostly undetected

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over 9.263 million cases and taken more than 477,000 lives as of June 24, 2020 – just six months after the initial outbreak in Wuhan, China, was reported. The illness, called COVID-19 disease, caused by SARS-CoV-2 is a severe pneumonic illness, caused by the entry of the virus into the type II alveolar cells.

USA riddled with SARS-CoV-2 - 80% undetected

The coronavirus pandemic is actively spreading across the globe, affecting 188 countries and territories. The United States remains the country with the highest number of infections. The official tally reveals that the U.S. has more than 2.347 million people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Evidence of link between ACE2 genotype and COVID-19 disease severity

A new study published on the preprint server medRxiv in June 2020 shows that variants in the ACE2 gene which encodes the enzyme receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 disease, are linked to the risk of severe disease.

New study defines the transmission of COVID-19 from mother to child

UC Davis Health researchers took a critical step in defining the possible paths for the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) causing COVID-19 to get transmitted from the mother to her newborn baby. The mother to fetal transmission is known as "vertical" transmission.

Exposure to SARS-CoV-2 can induce virus-specific T cell responses without seroconversion

A new study by researchers at Strasbourg University Hospital and published on the preprint server medRxiv* in June 2020 shows that COVID-19 antibody responses may sometimes be lacking following exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could lead to a significant underestimation of the number of infections and the number of individuals who have achieved immunity.

Male COVID-19 patients produce more SARS-CoV-2 antibodies than women

Health officials in the United Kingdom urge male coronavirus survivors to donate blood, particularly its convalescent plasma component. This comes after a new study has found that men produce more antibodies, which could make their plasma a valuable treatment against the coronavirus disease (COVID-19).

Smoking increases risk of COVID-19 for men but not women

Even as the COVID-19 pandemic continues to spread over the world, scientists have had to come to terms with the fact that they don’t know much about the SARS-CoV-2 or the disease it causes. Now, a new study by researchers at the University College Cork, Ireland, and published on the preprint server medRxiv in June 2020 discusses the differences in COVID-19 risk between men and women who smoke.

Antibodies against prevalent endemic human coronaviruses may provide cross-protection to SARS-CoV-2

Researchers from Qatar have demonstrated that antibody repertoires against endemic human coronaviruses are qualitatively different in children when compared to the general adult population, as well as healthy adult blood bank donors – and they may also provide cross-protection against epidemic/pandemic strains.

Pangolin version of SARS-CoV-2 can cause COVID-19-like illness

The results of a recent multinational research endeavor, currently available on the bioRxiv preprint server, display the biological framework of SARS-CoV-2-related coronavirus in pangolins and reveal striking similarities to coronavirus disease (COVID-19) in humans, but also show that it can be transmitted vertically to the fetus.

Female reproductive organs not susceptible to direct SARS-CoV-2 infection

Researchers at the University in San Francisco, California, report that coronavirus disease 2019 (COVID-19) is unlikely to negatively impact on pregnancy-related outcomes such as premature birth, transmission to babies via breast milk, and infertility.

FDA approved drugs active against COVID-19

With the rapid spread of the virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) throughout the world, causing the current COVID-19 pandemic, there is an urgent need for new antivirals and vaccines to combat its spread. The current study published on the preprint server bioRxiv in June 2020 shows some of the results of the extensive repurposing of already FDA-approved drugs.

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.

8.5 percent of COVID-19 patients do not seroconvert

A new study published on the preprint server medRxiv in June 2020 reports on the use of inexpensive and accurate ELISA and rapid diagnostic tests (RDT) to identify the demographic and clinical factors that affect the antibody response in COVID-19 patients.

Scientists find COVID-19 antibodies fade quickly

Now, a new study shows that the levels of antibodies found in recovered coronavirus disease (COVID-19) patients declined sharply in just two to three months after infection for both symptomatic and asymptomatic patients.
