MD65 IgG-YTE shows powerful post-exposure neutralization of SARS-CoV-2

A recent study published in the preprint server bioRxiv in October 2020 describes a reliable animal model to demonstrate the powerful capacity of human neutralizing mAbs directed against SARS-CoV-2 to prevent viral binding the host cell receptor and thus block infection. This indicates the lifesaving value of mAbs in severe COVID-19.

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.

Research uncovers SARS-CoV-2 viral traits critical for the virus in human airways

A new study published on the preprint server bioRxiv* in October 2020 reports the discovery of important viral genomic features that are crucial to its replication in the human airway cells, and its enhancing mutations which increase the rate of replication and determine its target cells.

Small molecules block SARS-CoV-2 spike-ACE2 attachment

The search includes immunological agents, enzyme inhibitors, and soluble competitive inhibitors. Now, a new study published on the preprint server bioRxiv in October 2020 provides preliminary evidence that small molecules can inhibit viral entry by inhibiting spike-ACE2 attachment.

NRP-1 receptor potentiates SARS-CoV-2 infectivity

The COVID-19 pandemic is still actively spreading in many parts of the world, causing redoubled efforts to develop antivirals and vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A recent study explores the role of a second type of cell surface receptor, called neuropilin, in the virus's entry into the host cell and its subsequent replication.

Neuropilin-1: A new route of SARS-CoV-2 entry

A new study published in the reputed journal Science in October 2020 reports the potential therapeutic value of the second type of host transmembrane receptor, called neuropilins, which attach to the spike protein of SARS-CoV-2 and may enhance its infectivity.

Researchers identify molecular processes in kidney cells that attract and feed COVID-19

Although the lungs are a common target for COVID-19's cytokine storm, so are the kidneys, making the 1 in 4 U.S. adults with diabetes resulting in diabetic kidney disease at increased risk for virus mortality.

Molecular processes in kidney cells may increase diabetics' vulnerability to COVID-19 infection

People with diabetes -- especially the 20 to 40 percent with diabetic kidney disease -- are among the most at risk for serious complications and death from COVID-19.

DNA vaccine-induced antibodies neutralize SARS-CoV-2

The coronavirus disease (COVID-19) is far from over as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to ravage across the globe. With the vast spread of the virus, many countries who reported flattening the curve over the past months have reported clusters of new cases and second waves of the outbreak.

Researchers use molecular dynamics simulations to identify secrets of SARS-CoV-2 virus

The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.

Brain metabolic changes associated with loss of smell in COVID-19

A recent study detailed in a preprint paper published in medRxiv, researchers from Belgium, discuss how they investigated possible central nervous system (CNS) involvement in COVID-19 patients with a sudden loss of smell using a hybrid positron emission tomography (PET)-magnetic resonance imaging (MRI) system (PET-MR).

Researchers explore SARS-CoV-2 at single cell resolution in human airway epithelial cells

The cellular tropism of the SARS-CoV-2 virus affects several aspects of infection, such as the spread of the virus within and between hosts, tissue pathology, immune control mechanisms, and the response to treatment with promising antiviral drugs.

Researchers explore effect of temperature on molecular structure of SARS-CoV-2 spike

Didac Martí et al., from the Polytechnic University of Catalonia, in a recent bioRxiv preprint research paper, explore the effect of the temperature on the molecular structure of the SARS-CoV-2 spike glycoprotein. The study specifically focuses on the spike glycoprotein's molecular structural integrity at different temperatures (within 25 ºC and 100 ºC) using atomistic computer simulations.

Engineered decoy receptor could protect against coronaviruses

Researchers in the United States have shown that an engineered soluble decoy receptor tightly binds the spike protein of severe acute respiratory syndrome (SARS)-associated viruses. This could potentially provide protection against zoonotic betacoronaviruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.
