Researchers identify new strategy to combat loss of skeletal muscle mass

Researchers at the University of São Paulo (USP) in Brazil have shown for the first time that stimulating expression of a protein naturally produced by the human body can be a strategy to combat loss of skeletal muscle mass, which happens normally with aging but can intensify in cases of neurodegenerative or inflammatory disease, or in patients who spend long periods in intensive care units (ICUs).

Research opens the possibility for new molecular probes and targeted drug delivery systems

Researchers at Kanazawa University monitored the emission of blue-green light from water-soluble tetraphenylethene molecules adsorbed at a phospholipid-adsorbed liquid-liquid interface made to resemble a biomembrane.

Computational study reveals SARS-CoV-2 spike protein structural stability

Using dynamic contact maps and energy differences between different conformations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (or S-protein), an international team of researchers have recently published an article on the bioRxiv preprint server showing the different stable conformations of the spike protein.

D614G mutation enhances stability of SARS-CoV-2 spike protein

A new study, published on the preprint server bioRxiv in November 2020 by researchers at the Indian Institute of Science, has explored this issue further. The researchers have found that this mutation is associated with structural and energetic changes that cause this spike variant to become more available during infection, thus rendering the associated strain more infective.

Engineers use electric fields to manipulate viruses in microfluidic device

The technique uses microfluidics -- the submillimeter control of fluids within a precise, geometric structure. On what is basically a tricked-out microscope slide, chemical engineers from Michigan Technological University have been able to manipulate viruses in a microfluidic device using electric fields.

Novel MRI contrast agent offers hope for early detection of Alzheimer’s disease

Hong Kong Baptist University scientists have invented a novel contrast agent for magnetic resonance imaging, which enables real-time visualization and detection of the size and number of amyloid-beta in the brain, a main hallmark of Alzheimer’s disease.

Scientists compare ACE2 interaction with SARS-CoV-2 across species

Like other pathogenic coronaviruses, SARS-CoV-2 crossed the species barrier to cause human disease. This fact motivated the current study, published on the preprint server bioRxiv* in October 2020, which explores the way coronaviruses engage their host cell receptors in a range of animals.

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.

Scientists identify new therapeutic targets for SARS-CoV-2

To identify new potential therapeutic targets for SARS-CoV-2, a team of scientists at the New York Genome Center, New York University, and the Icahn School of Medicine at Mount Sinai, performed a genome-scale, loss-of-function CRISPR screen to systematically knockout all genes in the human genome.

Researchers identify effective way to protect vulnerable people from COVID-19

T-cells taken from the blood of people who recovered from a COVID-19 infection can be successfully multiplied in the lab and maintain the ability to effectively target proteins that are key to the virus's function, according to a new study published Oct. 26 in Blood.

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 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.
