NIAID researchers identify key player in the immune response to SARS-CoV-2

When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective.

Scientists receive NIH grant to monitor COVID-19 in wastewater

Everyone poops, and now scientists are using this bodily function to develop a detailed analysis of the virus that causes COVID-19, known as SARS-CoV-2.

Development of a model of substrate coordination to Zn-bound ACE2

The ongoing coronavirus disease-19 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has claimed more than 2.8 million lives worldwide. Authorities are facing difficulty in preventing the spread of disease due to the highly infectious nature of SARS-CoV-2. Therefore, reducing the virus's ability to infect an individual's respiratory epithelial cells could prove an effective measure to prevent disease transmission.

Study of twins reveals differences in adaptive immunity towards SARS-CoV-2

Twins may look alike on the outside, but not so much on the inside. That's one takeaway from a new preprint study posted to the medRxiv server where Brazilian researchers observed different T-cell responses in two pairs of identical twins exposed to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). One twin who was reinfected with SARS-CoV-2 four months after had low recognition of CD4+ and CD8+ T-cell epitopes.

SARS-CoV-2 mutation T478K spreading at alarming speed in Mexico

Several SARS-CoV-2 variants have emerged, posing a renewed threat to COVID-19 containment and to vaccine and drug efficacy. In this study, we analyzed more than 820,000 SARS-CoV-2 genomic sequences deposited up to March 26, 2021 and identified a novel T478K mutation located on the SARS-CoV-2 Spike protein.

New research shows how to make people follow pandemic restrictions without fear

Making people fear the coronavirus may motivate us to wash our hands, keep our distance and wear a face mask. But fear also takes a heavy toll on our mental health and is fertile ground for discrimination and prejudice.

Microbiota-derived molecules do not change the entry or replication of SARS-CoV-2 in intestinal cells

A study conducted at the University of Campinas in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines.

Researchers examine the evolutionary race between SARS-CoV-2 and human defenses

Researchers have analyzed this evolution of the virus based on evolutionary ecology theory. Using the virus genomes available in the Global Initiative on Sharing Avian Influenza Data (GISAID) database, the researchers focused their inquiry on mutations in the receptor-binding domain (RBD) on the spike protein of SARS-CoV-2.
