Study shows P681H mutation is becoming globally prevalent among SARS-CoV-2 sequences

In a recent bioRxiv preprint study, researchers from the University of Hawaii showed that the S gene of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is continuously mutating according to the sequence and phylogenetic analysis.

Disulfide-reducing agents demonstrate potential antiviral activity against SARS-CoV-2

Researchers recently demonstrated that chemical agents capable of reducing disulfide (S-S) bonds can be potentially used as antiviral drugs against SARS-CoV-2, the causative pathogen of COVID-19.

Animal study suggests palmitoylation inhibitor reduces virulence of SARS-CoV-2

A new study preprint on the bioRxiv* server demonstrates the ability of a fatty acid synthase inhibitor to improve the survival of mice infected with murine hepatitis virus. In so doing, it adds to the sum of knowledge about the relationship of SARS-CoV-2 with cholesterol metabolism in the host cell.

Cholesterol in the plasma membrane is essential for SARS-CoV-2 entry and syncytia formation

A preprint indicates that SARS-CoV-2 requires cholesterol to accomplish entry into the host cells and membrane fusion.

Hepatitis C virus drugs synergize with remdesivir against SARS-CoV-2 in vitro

SARS-CoV-2 has infected over 71.5 million people and claimed over 1.6 million lives globally since December 2019.

Why are some groups more vulnerable to COVID-19?

News-Medical speaks to Dr. Jaswinder Singh about his research surrounding why some groups are more susceptible to severe cases of COVID-19.

Potential SARS-CoV-2 Mpro inhibitors identified by in silico screening

The search for effective inhibitors of SARS-CoV-2 is assuming new urgency as the fall/winter resurgence of the infection appears.

Biochemical cascade in the brain leads to the destruction of synapses in Alzheimer's

A new study on Alzheimer's disease by Scripps Research scientists has revealed a previously unknown biochemical cascade in the brain that leads to the destruction of synapses, the connections between nerve cells that are responsible for memory and cognition.

Understanding why some people are more vulnerable to COVID-19

What makes the elderly and people with underlying conditions more vulnerable to COVID-19? According to a new study led by McGill University researchers, clues can be found in the proteins involved in initiating infection, as the virus binds to host cells of different animals.

Are SARS-CoV-2 protease inhibitors effective antivirals in treating COVID-19?

Many antiviral development studies have focused on the possibility of inhibiting the main viral protease (Mpro), and papain-like protease (PLpro), given their central role in viral replication. A new study draws attention to the high odds that these may not have anti-infective activity because of the redundant pathways present in human host cells.

Drugs targeting neutrophils could reduce ARDS in severe COVID-19

Scientists in Taiwan recently published a report on their use of anti-neutrophil strategies to treat acute respiratory distress syndrome (ARDS) – a life-threatening condition that can arise in critical COVID-19 cases – in the journal Frontiers in Pediatrics.

Researchers identify acrylamides that inhibit SARS-CoV-2 main protease

A new study in the preprint server bioRxiv published in November 2020 describes the discovery of acrylamide fragments that can effectively disable key enzymes in both the hand, foot and mouth virus and SARS-CoV-2 virus.

SARS-CoV-2 spike glycoprotein optimized for conditions present in human airways

Researchers from Belgium and Germany demonstrated how the spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is fine-tuned towards the temperature and protease conditions of the human airways, which in turn enhances viral transmission and subsequent pathology. Their study is available on the bioRxiv* preprint server.

Promising yeast-expressed SARS-CoV-2 vaccine candidate effective in mice

Researchers at the Texas Children's Hospital Center for Vaccine Development, USA, have published a report on the preprint server bioRxiv that describes a yeast-expressed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) protein, a key target of current vaccine development efforts.

Study shows SARS-CoV-2 direct heart muscle cell infection, cell death, loss of contractility

In the study, published on the pre-print journal bioRxiv, the researchers revealed that SARS-CoV-2-infected EHTs manifested the typical characteristics of myocarditis or heart inflammation. These include the stimulation of immune cells, heart cell death, and decreased contractile force generation.

Furin cleavage site and D614G on SARS-CoV-2 spike evolved to balance infectivity, stability, cytopathicity

SARS-CoV-2 is the causative agent of COVID-19 disease, currently raging across the world. The virus has now infected more than 43.89 million individuals and claimed over 1.16 million lives. The study titled, "Spike glycoprotein and host cell determinants of SARS-CoV-2 entry and cytopathic effects," is released on the preprint server bioRxiv* in October 2020.
