Researchers explain SARS-CoV-2's replication-transcription complex

The current pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still spreading rapidly throughout the world. A new preprint on the bioRxiv* server describes the structure of an important viral non-structural protein NSP12-16 and its role in SARS-CoV-2 infection.

Some nutritional supplements may help prevent or mitigate COVID-19 severity

A new study in the Journal of dietary supplements shows that nutritional supplements, including several vitamins and the mineral zinc, may be useful in preventing the infection or reducing its severity if caught.

Periodontal inflammation associated with higher risk of major cardiovascular events

People with periodontitis are at higher risk of experiencing major cardiovascular events, according to new research from Forsyth Institute and Harvard University scientists and colleagues.

Superspreader events trigger emergence of novel SARS-CoV-2 variants in USA

A team of scientists from the USA and Germany has recently studied the evolution of SARS-CoV-2 in a representative set of sequences from the USA collected between 2020 and 2021. The findings reveal that the viral genome has accumulated multiple mutations over time with only occasional loss of mutation. The main driving forces behind such genetic variations include widespread infection and superspreader events.

Study profiles the nose to predict immune response during COVID-19

SARS-CoV-2 resides in mucous membranes, making it easy to detect viral load in the nasal cavities. An international group of researchers has characterized the immunological and diagnosis characteristics of patients who may have or are confirmed with SARS-CoV-2 infection. The team found a distinct nasal cytokine profile that could help identify patients at risk for high inflammatory responses to SARS-CoV-2 infection.

Study could lead to new strategies to prevent various cancers

Chronic inflammation drives the development of various cancers, including those of the skin, colon and pancreas. Investigators at Massachusetts General Hospital (MGH) who previously demonstrated high expression levels of an immune molecule called interleukin-33 (IL-33) during cancer-promoting inflammation have now uncovered the details behind the molecule's effects.

Some SARS-CoV-2 variants evade mRNA vaccine-induced humoral immune, says study

Understanding how variants escape vaccine-boosted immune function is necessary to neutralizing SARS-CoV-2. An international team of researchers from MIT and Harvard University in the USA analyzed Pfizer and Moderna vaccines' effectiveness in neutralizing spike proteins from 10 different strains of SARS-CoV-2.

Could an intranasal adjuvant to vaccines boost immunity against SARS-CoV-2 variants?

A research team from the University of Michigan Medical School, USA, developed a supplementary intranasal treatment to improve COVID-19 vaccine response and its effects on long-lasting immunity from other variants, such as the B.1.351 variant first found in South Africa.

22 Feb 2021

Study identifies immune profile of people with severe COVID-19

A team of researchers at Georgetown University Medical Center, USA, investigated how SARS-CoV-2 affects the immune system’s response during and after infection and contributes to the severity of COVID-19.

High fructose diets might prevent proper functioning of peoples' immune system

New research by Swansea scientists in collaboration with researchers at the University of Bristol and the Francis Crick Institute in London has indicated that consuming a diet high in sugar fructose might prevent the proper functioning of peoples' immune systems in ways that have, until now, largely been unknown.

Gold nanoparticles investigated as part of in vitro tool for SARS-CoV-2 drug screening

Scientists have measured the interaction of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein with nano-gold colloids. These nanoparticles functionalized with the S protein have different spectroscopic signals allowing for new information about the protein to be extracted.

Cissampelos pareira L. extracts demonstrate anti-SARS-CoV-2 activity in vitro

A team of scientists from India has recently investigated the antiviral potency of a traditional medicinal plant Cissampelos pareira L. in preventing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The findings reveal that both whole-plant extracts and bioactive compounds can inhibit SARS-CoV-2 replication by modulating estrogen receptor 1 (ESR1) activity.
