Immunome could provide unprecedented insight into an individual’s health

The human immune system doesn't just protect our health, it reflects it. Each encounter with a potential disease-causing agent causes the body to produce specific immune agents -- proteins known as antibodies and T-cell receptors -- tailor-made to recognize and destroy the invader.

Pan-COVID-19 vaccine protects mice against SARS-CoV-2 variants

Researchers in the United States have identified short peptide sequences in the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are immunogenic in a mouse model and may provide protection against viral variants.

Study uncovers protein 'signature' of severe COVID-19

Researchers at Massachusetts General Hospital have identified the protein "signature" of severe COVID-19, which they describe in a new study published in Cell Reports Medicine.

Researchers identify mechanism of platelet hyperactivation in COVID-19 patients

A recent study conducted at the University of Pennsylvania and the Children’s Hospital of Philadelphia, USA, has revealed the mechanism of platelet hyperactivation in critically ill coronavirus disease 2019 (COVID-19) patients.

Moderna COVID-19 vaccine makes it on WHO Emergency Use Listing

Moderna has announced Emergency Use Listing granted by the World Health Organization for its COVID-19 mRNA vaccine.

Could in vitro glycoengineering help produce better SARS-CoV-2 spike candidates for vaccine research?

A vexing problem in the development of vaccines has been the need to achieve the right glycosylation profile for the viral antigens. A new study, recently released as a preprint on the bioRxiv* server, shows how a sequential cell-free approach produced complex N-glycans from simpler types, in a one-pot reaction.

Rapid and sensitive SARS-CoV-2 detection from saliva using CRISPR

In a paper recently uploaded to the preprint server medRxiv by Edward Málaga Trillo et al. (April 29th, 2021), these methods are tested in combination with CRISPR-Cas detection in the field, demonstrating a sensitivity and specificity of 93.8% and 99%, respectively.

Monoclonal antibody neutralizes all SARS-CoV-2 variants of concern

Researchers in Canada and the United States have identified a monoclonal antibody that potently neutralizes variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the ongoing coronavirus disease 2019 (COVIdD-19) pandemic.

SARS-CoV-2 antibodies are detectable up to a year after infection, finds study

A team of scientists from the United States has recently investigated the robustness and durability of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in coronavirus disease 2019 (COVID-19) patients. Their findings reveal that COVID-19 patients exhibit a strong anti-SARS-CoV-2 antibody response for up to 1 year and that the robustness of antibody response depends on the patient’s age and disease severity.

SARS-CoV-2 spike mutations during transmission among humans and to animals

A fascinating new study discusses the 40 mutations that are seen on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein and their potential effects on viral biology.

COVID-19 may not have appeared first in China, suggests new genomic study

A new study in Acta Mathematica Scientia suggests that the virus may have originated in multiple countries almost simultaneously, rather than spreading from China to the rest of the world.

Hopeaphenol inhibits entry of SARS-CoV-2 variants of concern into cells

A new study, released as a preprint on the bioRxiv* server, reports promising results with the natural product hopeaphenol, which successfully prevented the entry of the virus into host cells.

Discovery opens new avenues for developing antibody-based therapies for malaria

WEHI researchers have identified how natural human antibodies can block malaria parasites from entering red blood cells, potentially indicating how new protective therapies could be developed against this globally significant disease.

A new SARS-CoV-2 variant (HMN.19B) has been identified in France

New research published in the Centers for Disease Control and Prevention’s journal Emerging Infectious Diseases has confirmed the emergence of a new SARS-CoV-2 variant called HMN.19B from the viral clade 19B in France. The 19B viral clade — which includes the D614G variant — was prevalent in late 2019 but had since been rarely observed since early 2020 because of newer viral clades.

Vaccine candidate targeting SARS-CoV-2 nucleocapsid protein elicits protective immune response in animal model

New preclinical results from a study led by David Masopust of the University of Minnesota in Minneapolis, USA, show that a Had5-based vaccine targeting the nucleocapsid protein can also elicit a protective immune response.

Competitive multiplex binding assay can monitor SARS-CoV-2 immune responses using nanobodies

Researchers at the Eberhard Karls University and the University of Tübingen in Germany described 11 unique nanobodies (Nbs) specific for the SARS-CoV-2 spike receptor-binding domain (RBD), of which 8 Nbs potentially inhibit the connection of RBD with the angiotensin-converting enzyme 2 (ACE2).

Study reveals new broadly neutralizing and protective antibody against coronaviruses

In the setting of potentially reduced vaccine efficacy against coronavirus disease (COVID-19) due to emerging viral variants, the deployment of effective treatments based on monoclonal antibodies may be an additional strategy to help control the pandemic. A new study by US researchers, currently available on the bioRxiv* preprint server, describes the action of a specific antibody known as DH1047.

Researchers develop a nanoparticle-based formulation with anti-SARS-CoV-2 activity

A study recently published in the journal Matter has demonstrated the development and validation of a nanoparticle-based formulation, capable of completely inhibiting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection blocking the interaction between viral spike protein and host cell angiotensin-converting enzyme 2 (ACE2).

Previously infected vaccinees broadly neutralize SARS-CoV-2 variants of concern

Researchers in the United States have conducted a study demonstrating the effectiveness of first-generation vaccines at protecting against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals who have previously been infected with the virus.
