Antibody profile and estimated seroprevalence in COVID-19 infection

A new Swedish study published on the preprint server medRxiv in July 2020 describes the results of using highly sensitive and specific anti-spike antibody tests in a cohort of patients with COVID-19 over a range of disease severity.

Analysis of the SARS-CoV-2 proteome via visual tools

Now, a new study published on the preprint server bioRxiv* in July 2020 shows how this can be advanced at a greater speed by combining experimental results with homology models obtained by high-throughput pipelines. This will help produce new hypotheses that will show novel druggable targets for effective drug development.

Doctor in Israel reinfected with COVID-19 three months after recovering

There is still a lot to learn about coronavirus disease (COVID-19), which is currently ravaging across the globe. Though scientists are slowly gaining a better understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it is still unclear if being infected once may provide long-lasting immunity against the novel coronavirus.

New nanoparticle vaccine for SARS-CoV-2 shows protective traits in preclinical study

A new nanoparticle vaccine for SARS-CoV-2, the virus that causes COVID-19, has shown hints of protection and immunity in a preclinical study, safely eliciting the production of antibodies and antiviral T cell responses in mice and pigtail macaques.

COVID-19 vaccine displays protective traits in nonhuman primates

A replicating RNA vaccine, formulated with a lipid-based nanoparticle emulsion that goes by the acronym LION, produces antibodies against the COVID-19 coronavirus in mice and primates with a single immunization. These antibodies potently neutralize the virus.

China's Ad5 vectored COVID-19 vaccine safe and induces immune response

A phase 2 trial of an Ad5 vectored COVID-19 vaccine candidate, conducted in China, has found that the vaccine is safe and induces an immune response, according to new research published in The Lancet.

Experimental therapy slows zika replication and prevents microcephaly in mice

An international group of researchers have discovered that inhibiting AHR (aryl hydrocarbon receptor), a protein with roles in regulating immunity, stem cell maintenance and cellular differentiation, enables the immune system to combat replication of zika virus in the organism far more effectively.

Benefits of routine childhood immunizations far outweigh the risk of SARS-CoV-2 transmission

The health benefits of maintaining routine childhood vaccination programmes in Africa during the COVID-19 pandemic far outweigh the risk of SARS-CoV-2 transmission that might be associated with clinic visits, according to a modelling study published in The Lancet Global Health journal.

Researchers are producing COVID-19 spike proteins to prevent future infections

On July 1, the Texas A&M Engineering Experiment Station's National Center for Therapeutics Manufacturing received funding from the National Institute for Innovation in Manufacturing Biopharmaceuticals to help find a way to prevent the SARS-CoV-2 virus from binding to cells, protecting people from future infections.

Perspective: T cell reaction to SARS-CoV-2 virus is a crucial target for research

While early research on the adaptive immune response to COVID-19 primarily looked at antibodies, more information is now emerging on how T cells react to the SARS-CoV-2 virus - addressing a crucial knowledge gap, say Daniel Altmann and Rosemary Boyton in a new Perspective.

More COVID-19 cases where blood type A is common

Now, a new study by researchers at the University of Ulm, Germany, which is published on the preprint server medRxiv in July 2020, focuses on how blood group distribution is related to the mapped dynamics of the epidemic as shown by its geographical distribution.

Findings show promise for developing vaccines against multiple strains of flu, including SARS-CoV-2

A vaccine additive known as an adjuvant can enhance responses to a vaccine containing the exotic avian flu virus H5N1, so that both rookie and veteran elements of the immune response are strengthened, according to results from an Emory Vaccine Center study.

Study could help develop new drugs for toxoplasma infection

Researchers at Indiana University School of Medicine have discovered new information about how a dangerous parasite takes control of a patient's cells as it spreads throughout their body, an important finding that could help in the development of new drugs to treat this infection.

Newly identified enzyme provides a new tool in CRISPR genome editing toolbox

A recently discovered hypercompact CRISPR enzyme found only in huge bacteriophages, and known as CRISPR-CasΦ, is functional, a new study by Patrick Pausch, Jennifer Doudna and colleagues reports, and it provides a powerful new tool in the CRISPR genome editing toolbox, including because it can target a wider range of genetic sequences compared to Cas9 and Cas12.

Game-Changer: A SARS-CoV-2 serological test for 50-cents per sample!

A recent study published in the preprint server medRxiv in July 2020 shows that this is indeed possible. The development of this inexpensive but reliable and sensitive test could change the face of preventive measures for COVID-19 in low-resource settings.

Singapore study finds virus-specific T cell immunity in recovered COVID-19 and SARS patients

The T cells, along with antibodies, are an integral part of the human immune response against viral infections due to their ability to directly target and kill infected cells.

New insight into the SARS-CoV-2 infection process

Canadian researchers from the Department of Neurology and Neurosurgery, Montreal Neurological Institute, McGill University, Montreal, QC, have found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be using a unique method to gain entry into the cells.
