A new SARS-CoV-2 variant (HMN.19B) has been identified in France

New research published in the Centers for Disease Control and Prevention’s journal Emerging Infectious Diseases has confirmed the emergence of a new SARS-CoV-2 variant called HMN.19B from the viral clade 19B in France. The 19B viral clade — which includes the D614G variant — was prevalent in late 2019 but had since been rarely observed since early 2020 because of newer viral clades.

Vaccine candidate targeting SARS-CoV-2 nucleocapsid protein elicits protective immune response in animal model

New preclinical results from a study led by David Masopust of the University of Minnesota in Minneapolis, USA, show that a Had5-based vaccine targeting the nucleocapsid protein can also elicit a protective immune response.

Competitive multiplex binding assay can monitor SARS-CoV-2 immune responses using nanobodies

Researchers at the Eberhard Karls University and the University of Tübingen in Germany described 11 unique nanobodies (Nbs) specific for the SARS-CoV-2 spike receptor-binding domain (RBD), of which 8 Nbs potentially inhibit the connection of RBD with the angiotensin-converting enzyme 2 (ACE2).

SARS-CoV-2’s distinctive "spike" protein plays a key role in the disease itself, shows study

Scientists have known for a while that SARS-CoV-2's distinctive "spike" proteins help the virus infect its host by latching on to healthy cells. Now, a major new study shows that they also play a key role in the disease itself.

Study finds one-third of COVID-19 patients experience neurological symptoms

The research on the short and long-term effects of COVID-19 disease is ongoing. Still, scientists have found severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects the brain causing loss of smell and taste, dizziness, muscle pain, fatigue, and other cognitive impairments. However, it remained unknown why certain people developed neurological symptoms while others did not.

Low-profile thoracic aortic endograft minimizes complications, increases patient pool

Preliminary results of a clinical trial, presented today at the AATS 101st Annual Meeting, showed that a new, low-profile thoracic aortic endograft is safe and effective in the treatment of descending thoracic aortic aneurysm or penetrating atherosclerotic ulcer (PAU) diseases.

Study estimates true number of COVID-19 deaths by U.S. county

Every country has been affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has spawned a pandemic. For several factors, the United States has been hit hard by the number of coronavirus cases and death. The country currently leads the world with over 32.4 million infections and more than 577,000 COVID-19 deaths.

Comprehensive "cell atlas" shows how COVID-19 can lead to organ failure and death

Scientists from several hospitals and research centers have shown what happens in individual cells of patients who died of COVID-19. In a study published in Nature, the researchers describe how infected cells from multiple organs exhibited a range of molecular and genomic changes.

Interdisciplinary project explores the phenomenon of so-called “superspreaders”

Scientists from the Departments of Physics, Biomedical Sciences and Process Engineering at Otto von Guericke University Magdeburg are in the process of analyzing the emergence and spread of infectious air bubbles in our breath, known as aerosols, using tissue cultivations and artificially-produced, virus-filled suspended particles.

Researchers identify novel SARS-CoV-2 variant with mutations in membrane protein-encoding gene

A recent study published in the Journal Emerging Microbes and Infections has highlighted the emergence of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant with mutations in the membrane protein-encoding gene. Two potential mutations, M:I82T and M:V70L, have been identified within the transmembrane helices, which are expected to improve viral fitness by modulating glucose uptake during replication.

Researchers develop a nanoparticle-based formulation with anti-SARS-CoV-2 activity

A study recently published in the journal Matter has demonstrated the development and validation of a nanoparticle-based formulation, capable of completely inhibiting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection blocking the interaction between viral spike protein and host cell angiotensin-converting enzyme 2 (ACE2).

Could CRISPR be used as a SARS-CoV-2 antiviral?

The potential of using this gene manipulation technology as a SARS-CoV-2 inhibitor or prophylactic is investigated in a review recently uploaded to the journal Experimental Biology and Medicine (April 25th, 2021) by Arnab Banerjee and colleagues.

Study implies a likely rise of future SARS-CoV-2 recombinants

A recent astonishing feat by US researchers revealed that recombination is not only widespread in the evolutionary history of SARS-like coronaviruses, but it can also increase fitness traits of seasonal coronaviruses. Their paper is currently available on the bioRxiv* preprint server and sets the stage for phylogenetic tracking of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Live "attenuated" influenza virus vaccine protects animals against respiratory infections, including SARS-CoV-2

Researchers in the United States and Austria have demonstrated the potential of a modified influenza virus as a vaccine to protect against viral respiratory pathogens, including the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Previously infected vaccinees broadly neutralize SARS-CoV-2 variants of concern

Researchers in the United States have conducted a study demonstrating the effectiveness of first-generation vaccines at protecting against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals who have previously been infected with the virus.

Too much salt affects the functioning of phagocytes

For many of us, adding salt to a meal is a perfectly normal thing to do. We don't really think about it. But actually, we should. As well as raising our blood pressure, too much salt can severely disrupt the energy balance in immune cells and stop them from working properly.

New technology enables faster and more accurate tracing of COVID-19 and other viruses

Jeremy Edwards, director of the Computational Genomics and Technology (CGaT) Laboratory at The University of New Mexico, and his colleagues at Centrillion Technologies in Palo Alto, Calif. and West Virginia University, have developed a chip that provides a simpler and more rapid method of genome sequencing for viruses like COVID-19.
