Study suggests SARS-CoV-2 Omicron variant spike mediated immune escape and tropism shift

A new study showed that the SARS-CoV-2 Omicron spike binds to its receptor with enhanced affinity and yet evades vaccine-elicited neutralizing antibodies and that a booster mRNA vaccine broadened the neutralization of Omicron.

Cannabidiol found to inhibit SARS-CoV-2 infection in human cells and mice

An interdisciplinary team of researchers from the University of Chicago has found evidence that cannabidiol (CBD), a product of the cannabis plant, can inhibit infection by SARS-CoV-2 in human cells and in mice.

Nano-bubbles containing ACE2 protein can block infection from broad strains of SARS-CoV-2

Scientists at Northwestern Medicine and The University of Texas MD Anderson Cancer Center have identified natural nano-bubbles containing the ACE2 protein (evACE2) in the blood of COVID-19 patients and discovered these nano-sized particles can block infection from broad strains of SARS-CoV-2 virus in preclinical studies.

The tetrapeptide tuftsin effectively impairs the binding of SARS-CoV-2 S1 to ACE2

In their recent study posted to the preprint server bioRxiv*, the researchers from China have shown that tuftsin, a natural phagocytosis-stimulating peptide, can effectively impair the binding of SARS-CoV-2 spike S1 subunit to ACE2 receptor in a dose-dependent manner and therefore can be considered a potential drug against SARS-CoV-2 infection.

Researchers explore furin inhibitors as a potential tool for treating COVID-19 infection

A new study suggests that coronaviruses such as SARS-CoV-2 depend on a furin cleavage site between the S1/S2 subunits to enhance viral infectivity.

Scientists explore the possibility of Omicron ending the COVID-19 pandemic

A new analysis parses out what scientists currently know about the Delta variant and predicts what the end of the COVID-19 pandemic might look like.

Natural extracellular vesicles containing ACE2 protein could fight new SARS-CoV-2 variants

Scientists at The University of Texas MD Anderson Cancer Center and Northwestern Medicine have identified natural extracellular vesicles containing the ACE2 protein (evACE2) in the blood of COVID-19 patients that can block infection from broad strains of SARS-CoV-2 virus in preclinical studies. The study was published today in Nature Communications.

Study simulates transmission of SARS-CoV-2 in airliner cabins

A study published in Indoor Air simulated the transmission of SARS-CoV-2, the virus that causes COVID-19, on a flight from London to Hanoi and on another flight from Singapore to Hangzhou.

Study finds Omicron infection effectively induces immunity against itself and enhances protection against other variants in vaccinated individuals

Researchers investigated the effectiveness of the SARS-CoV-2 Omicron-variant induced immunity, whether it is cross-protective against other variants, and if earlier infection with the SARS-CoV-2 Delta variant offers protection against Omicron.
