An improved tetravalent antibody blocks SARS-CoV-2 infection

A new study published on the preprint server bioRxiv* in June 2020 shows the potential of a new fusion molecule called a biparatopic protein to inhibit viral interaction with the host cell ACE2 receptor. This could lead to therapeutic applications.

SARS-CoV-2 mutated spike proteins show variations in cell entry

A new study by Japanese scientists published on the preprint server bioRxiv* in June 2020 shows that the D614g mutation in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein can enhance the infectivity of the virus while leaving it vulnerable to neutralization by antibodies.

Norway pulls coronavirus contact tracing App due to privacy concerns

Amid the coronavirus pandemic, many countries have launched contact tracing apps to help contain the spread of the virus. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across most of the world, now infecting more than 8.17 million people; hence, extensive contact tracing is a vital tool to prevent its vast spread.

Beijing lockdown due to new SARS-CoV-2 cluster, New Zealand records first case in weeks

China had started to return to normalcy after successfully "flattening the curve," with the government slowly easing restrictions and opening up the economy. However, Beijing has reported new clusters of coronavirus disease (COVID-19) cases, prompting the implementation of lockdown measures.

Scientists isolate powerful SARS-CoV-2 -neutralizing antibodies from COVID-19 patients

A new study has shown that potent antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could help protect against COVID-19 infection. Preliminary results in animal studies have so far proven successful. The study titled, "Isolation of potent SARS-CoV-2 neutralizing antibodies and protection from disease in a small animal model," was published in the latest issue of the journal Science.

Antibiotic X-206 effective against SARS-CoV-2 in vitro

The current study published on the preprint server bioRxiv aims to understand how these compounds affect SARS-CoV-2 in vitro. The researchers from Aarhus University in Denmark examined 11 natural PEIs, with a single synthetic analog, screening them for inhibitory activity against the CPE of SARS-CoV-2 infecting cultured cells with overexpression of TMPRSS2, a serine protease that is instrumental in cleaving the spike protein of the virus.

How antibodies neutralize SARS-CoV-2 in convalescent patients

A new study by researchers from the United Kingdom and Taiwan and published on the preprint server bioRxiv in June 2020 describes the structural basis for the neutralizing effect of the SARS-CoV-2 antibody on the virus. This also indicates a possible therapeutic molecule by identifying its binding epitope as possibly a major neutralizing site.

Scientists evaluate SARS-CoV-2 infection risks in livestock, poultry, pets and wildlife

A large-scale single-cell screening endeavor on a wide variety of animals showed that cells targeted by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are most abundant in cats, but are also found in other animals – unveiling a valuable resource for controlling the ongoing disruptive coronavirus disease (COVID-19) pandemic.

Severity of COVID-19 linked to heparanase activity and heparan sulfate levels

Researchers at Radboud University Medical Center in the Netherlands reported an increase of heparanase activity and heparan sulfate levels in the plasma of patients with coronavirus disease (COVID-19), which was also associated with the severity of the condition – suggesting, in turn, potential treatment utility of low molecular weight heparins. The paper is currently available on the medRxiv* preprint server.
