SARS-CoV-2 a dagger to the aging heart

Researchers in Europe have shown that genes involved in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are expressed to a higher degree in older heart muscle cells (cardiomyocytes) than they are in younger cardiomyocytes.

Scientists identify compounds that block replication of COVID-19 virus

As the death toll from the COVID-19 pandemic mounts, scientists worldwide continue their push to develop effective treatments and a vaccine for the highly contagious respiratory virus.

Genomics used to trace origin of SARS-CoV-2 in Canada

A new study published in June 2020 on the preprint server bioRxiv discusses the use of phylogenetic analysis to trace the origin of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and its spread into and then within Canada. The study findings may help optimize public health policies in the case of future outbreaks.

Genes associated with SARS-CoV-2 human lung cell infection

Now, a new study published on the preprint server bioRxiv in June 2020 attempts to make sense of this data to identify viral genes that are explicitly expressed in the cells infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could help reveal new therapeutic targets.

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.

Crystal structure of SARS-CoV-2 protease-inhibitor in complex with a Chinese herb Shikonin

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has been spreading rampantly over the whole world, infecting millions of people (over 8.45 million at last count), with over 452,000 deaths, as of June 19, 2020. It causes a broad spectrum of disease manifestations, from asymptomatic disease to severe or even fatal respiratory symptoms.

Study reports structure of enzyme activator for high pathogenic avian influenza

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the current pandemic of COVID-19, is the focus of many investigators seeking to find an effective vaccine or therapeutic. Among the potential targets are various protease enzymes suspected of allowing the virus to gain entry to host cells and establish a successful infection.

Unique mutations could weaken Indian SARS-CoV-2 strain

A new study published on the preprint server bioRxiv in June 2020 suggests that the presence of unique mutations in the viral strains circulating in India has led to their attenuation.

A closer look at TMPRSS2: This could help treat COVID-19

The transmembrane protease serine-type 2 (TMPRSS2) protein plays a key role in COVID-19 infection since it primes the viral spike protein to allow viral entry into the target cell. A new study by researchers at Imperial College London and published on the preprint server bioRxiv in May 2020 describes the protein, which could be an attractive drug target to help manage COVID-19.
