Fluorescence-based assay for detecting SARS-CoV-2 neutralizing antibodies

Researchers have developed a rapid assay to rapidly detect neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using an imaging technique they developed for the Ebola virus.

The genetic diversity of SARS-CoV-2 in the USA

In a research paper recently uploaded to the preprint server medRxiv by Capoferri et al. (June 4th, 2021), the genetic diversity of SARS-CoV-2 through each phase is examined in detail using publicly available genomic data available from before 2021, highlighting the need to continuously track and assess the evolution of the virus to ensure the future efficacy of the currently available vaccines.

Study observes broad and invariable memory B cell response following SARS-CoV-2 infection

A new study by researchers at the Oregon Health & Science University (OHSU) in the USA goes far in answering this question by showing the presence of memory B cells that react to the original SARS-CoV-2 as well as VOCs.

Study offers overview of SARS-CoV-2 infection in children

A new study by researchers in the USA summarizes what is known about the prevalence of the infection, the viral load and transmissibility in children.

Could COVID-19 vaccinations or prior infections protect against other coronaviruses?

A new study provides encouraging proof of the feasibility of this project, showing that both natural infection with and vaccination against SARS-CoV-2 are associated with an increase in cross-reactive antibodies against other CoVs.

Seroprevalence study of SARS-CoV-2 infection in domestic cats

To monitor the occurrence of trans-species transmission, researchers from the Institute of Diagnostic Virology, Friedrich-Loeffler-Institut, Germany, conducted a survey of seroprevalence in domestic cats.

Vaccination against SARS-CoV-2 with a single dose skin patch

Researchers from Australia recently reported a high-density microarray patch used to deliver a SARS-CoV-2 spike subunit vaccine to the skin directly. They used a combination of a SARS-CoV-2 spike protein vaccine candidate and the high-density microarray patch (HD-MAP) vaccine delivery platform.

Impact of maternal SARS-CoV-2 infection on neonatal immunology

Although extensive studies have been carried out on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and evidence exists that pregnant women are at elevated risk of severe COVID-19, the impact of maternal infection on the fetus is not clear. The majority of pregnant women infected with SARS-CoV-2 are asymptomatic or experience mild symptoms.

Comparison of immunological profiles of SARS-CoV-2 variants

Mutations to the spike protein and receptor-binding domain are responsible for these changes in immunogenic profile, and in a paper recently uploaded to the open access journal Antibiotics by Ambrose et al. (May 6th, 2021) these mutations are correlated with various disease parameters by in silico methods, finding that particular features are responsible for the increased infectiousness and lesser disease severity observed in these lineages.

SARS-CoV-2 genome analysis reveals new 'Mexican variant'

A research group of the Department of Pharmacy and Biotechnology of the University of Bologna analyzed more than one million SARS-CoV-2 genome sequences.

Missing antibody molecule may predict disease severity in secondary dengue infection

A first encounter with the dengue virus typically causes very mild symptoms; however, a subsequent infection is a different story.

Maternal SARS-CoV-2 infection imprints immune response in the newborn

A new bioRxiv* preprint reports the immunological footprint in the newborn left by maternal infection with SARS-CoV-2 during pregnancy.

SARS-CoV-2 evades neutralizing antibodies and rapidly spreads by cell fusion, finds study

In a new study by researchers in the UK, Germany and South Africa, this process is visualized using time-lapse microscopy of a human cell lung line, demonstrating that SARS-CoV-2 can induce cell-to-cell fusion within 6 hours post-infection. Further, the application of neutralizing monoclonal antibodies or convalescent plasma was unable to prevent the spread of the virus by this mechanism, suggesting that removing SARS-CoV-2 from cells permissive of cell membrane fusion could be more difficult than other types of cell.

FDA weighs approval of a lucrative Alzheimer’s drug but benefits are iffy

The Food and Drug Administration's decision next week whether to approve the first treatment for Alzheimer's disease highlights a deep division over the drug's benefits as well as criticism about the integrity of the FDA approval process.

How mass screening efforts have helped identify more cases of celiac disease in children

A new mass screening program of school-aged children in Italy found that the overall prevalence of celiac disease has almost doubled in the past 25 years.

Three cases of stroke reported in young adults following covid-19 vaccination

Clots in the arteries (arterial thrombosis) are the most common cause of stroke (ischemic stroke) and have been reported in detail for the first time in young adults who received the Oxford–AstraZeneca covid-19 vaccine in a letter from UK stroke specialists published online in Journal of Neurology Neurosurgery & Psychiatry.

Waters launches new RUO LC-MS test method to advance infectious disease research

Waters Corporation today introduced a new RUO LC-MS test method to advance critical infectious disease research.

World Health Organization simplifies names of SARS-CoV-2 variants

Now, the World Health Organization (WHO) has assigned simple and easy-to-say labels for key variants of SARS-CoV-2 using letters of the Greek alphabet. The health agency selected these labels after a thorough review of many potential naming systems.

New strategy for developing universal flu vaccine

A new study from the University of Chicago and Scripps Research Institute shows that during the last great pandemic--2009's H1N1 influenza pandemic--people developed strong, effective immune responses to stable, conserved parts of the virus.

New research focuses on cow's milk as a possible source of COVID-19 control

Physiologically, milk contains biocomponents that are highly protective against infections. In light of this, the AGR-149-Infectious Diseases group at the University of Cordoba's Department of Animal Health is doing research that focuses on cow's milk as a possible source of Covid-19 control. The results have been published, partially, in the journal Frontiers in Immunology.
