New clinical report on brain changes in deceased COVID-19 patients

German researchers published a report on a series of cases on post mortem findings of COVID-19 patients who succumbed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection along with neurological complications. Their study titled “Neuropathology of patients with COVID-19 in Germany: a post-mortem case series” is published in the latest issue of The Lancet Neurology.

New approach to reveal high-resolution protein structural details

The number of proteins in the human body, collectively known as the proteome, is vast. Somewhere between 80,000 and 400,000 proteins circulate in our cells, tissues and organs, carrying out a broad range of duties essential for life.

Study shows how mysterious molecular concept could be used to target diseased cells

A growing area of medicine looks at how cellular binding observed in nature - where molecules like viruses or proteins bind to specific receptors on a cell - can be mimicked to aid drug delivery.

Plasma ACE2 concentration associated with increased risk of major cardiovascular events

A team of scientists at the Population Health Research Institute, Hamilton Health Sciences, and McMaster University, Hamilton, in Ontario, Canada, revealed that increased plasma ACE2 levels in the blood could indicate a higher risk of major cardiovascular events. The study is published in the journal The Lancet.

Development of a coarse-grained model of SARS-CoV-2 virion

A team of scientists of the University of Chicago and the University of California San Diego has developed a coarse-grained (CG) model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virion. The model can be used as a valuable resource to perform multiscale simulations of the SARS-CoV-2 virion. The study is currently available on the bioRxiv* preprint server.

Eli Lilly's LY-CoV555 antibody shows potential as COVID-19 treatment

Researchers in the United States and Canada have discovered a monoclonal antibody that potently neutralizes severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Study confirms SARS-CoV-2 spike glycoprotein promotes a hyper-inflammatory immune response

A group of researchers from Australia and China recently demonstrated how SARS-CoV-2 spike glycoprotein subunit 1 can induce a pro-inflammatory signaling pathway (leading to cytokines deployment and epithelial damage in human bronchial epithelial cells), but also highlighted the potential of peptide-based antivirals in tackling this novel coronavirus.

Macrophage subgroups may play pivotal role in COVID-19 lethality

Many researchers are attempting to identify risk factors for severe or critical COVID-19. A recent paper in the journal Medical Hypotheses in September 2020 suggests that macrophage class activation is one of the factors that determine the clinical phenotype of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Advanced model reveals dynamic motions of SARS-COV-2 spike-shielding glycans

A recent paper published on the preprint server bioRxiv in September 2020 discusses the dynamic interactions of the spike protein glycan shield, which may be of great value in developing therapeutic compounds to fight severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Sebum changes in COVID-19 patients, for future testing and prognosis

Now, a new study published on the preprint server medRxiv in September 2020 shows that sebum lipids change in COVID-19. This could help develop a cheap and straightforward method of non-invasive diagnosis.

More evidence Pangolin not intermediary in transmission of SARS-CoV-2 to humans

The team proposed a different model named the ‘circulation model’ to illustrate how SARS-CoV-2-related coronaviruses could have circulated in different species, including humans, before COVID-19 emerged.

Furin cleavage site of SARS-CoV-2 spike glycoprotein enhances viral replication in the lungs

In a new bioRxiv* preprint paper, researchers from the Imperial College London, King's College London, and the University of Bristol in the United Kingdom show that the furin cleavage site of SARS-CoV-2 spike glycoprotein represents a key determinant for transmission among humans, as it substantially facilitates replication in airway cells - opening the door for the development of novel therapeutics.
