Nucleocapsid-based vaccines may prevent SARS-CoV-2 dissemination to distal organs

A team of scientists recently investigated and compared the efficacy of spike-based and nucleocapsid-based COVID-19 vaccines in mice infected with SARS-CoV-2. Their findings reveal that nucleocapsid-based vaccines are effective in preventing SARS-CoV-2 infection in distal organs, such as the brain.

SARS-CoV-2 suppresses the immune response in the gut

In an effort to determine the potential for COVID-19 to begin in a person's gut, and to better understand how human cells respond to SARS-CoV-2, the scientists used human intestinal cells to create organoids - 3D tissue cultures derived from human cells, which mimic the tissue or organ from which the cells originate.

Researchers develop eleven SARS-CoV-2 RBD nanobodies using computational design

To develop therapeutics that block this binding process, a team of researchers recently used an integrated computational approach to design nanobodies (Nbs) against the SARS-CoV-2 RBD, using neutralizing/monoclonal antibodies specific to RBD of the spike protein.

Pandemic imperiled non-English speakers more than others

In March 2020, just weeks into the Covid-19 pandemic, the incident command center at Brigham and Women’s Hospital in Boston was scrambling to understand this deadly new disease. It appeared to be killing more Black and brown patients than whites. For Latinos, there was an additional warning sign: language.

New study looks at the impact of Covid-19 pandemic on UK healthcare

Just one third of people in the UK managed to access the hospital care they needed at the peak of the first wave of the Covid-19 pandemic – according to new research from the University of East Anglia.

First cases of B.1.1.7 variant with E484K mutation in Pennsylvania

The E484K mutation has also been found on the B.1.351 and P.1 variant, contributing to their status as variants of concern. In February 2021, Public Health England published a report of 11 B.1.1.7 genomes that also had the E484K spike mutation. Currently, there are 247 isolates of B.1.1.7 + E484K reported globally, and new research finds the first reports of it in southeastern Pennsylvania.

Triple mutation in SARS-CoV-2 seen in second wave of COVID-19 in India

Researchers sequenced the viral genome from samples in the state of Maharashtra and found a unique combination of three mutations that suggest the SARS-CoV-2 virus is continually evolving to evade the human immune response.

Nanobodies neutralize SARS-CoV-2 in pre-clinical model

A team of Australian researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI), the Doherty Institute, and the Kirby Institute have identified neutralizing nanobody cocktails that block the SARS-CoV-2 virus from entering cells in pre-clinical models.

Research suggests that Ginkgo biloba extract contains naturally occurring inhibitors against SARS-CoV-2

Researchers at Shihezi University in China found that Gingko Biloba leaves extract contains the most potent SARS-CoV-2 3-Chymotrypsin-like protease (3CLpro). This virally encoded main proteinase is essential for viral replication in coronaviruses.

Study reveals a hidden role of circulating microRNA as a driver of SARS-CoV-2 infection

In a methodological tour-de-force study, a large group of researchers from the USA and the United Kingdom analyzed patient transcriptomic data in-depth and discovered a circulating microRNA (miR-2392) that is directly implicated in the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) machinery during the infection process.

Study finds no evidence to support link between ABO blood group and COVID-19 risk

Researchers from the Boston University School of Public Health in the United States say there is no evidence to support a correlation between ABO blood group and the risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or the severity of coronavirus disease 2019 (COVID-19).

Prior SARS-CoV-2 infection and Pfizer-BioNTech’s COVID-19 vaccine provide similar immunity

Researchers in Israel have conducted a study showing that the immunity provided against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease (COVID-19) – is similar following natural infection or immunization with the Pfizer-BioNTech BNT162b2 vaccine.
