An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

Regeneron mAb cocktail benefits hospitalized patients with no natural SARS-CoV-2 antibody response

Researchers reporting on findings from the Randomized Evaluation of COVID-19 Therapy (RECOVERY) trial in the UK are recommending that any therapeutic use of REGEN-COV may be best restricted to individuals without detectable antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

The role of natural killer cells in fight against viral infections including SARS-CoV-2

In an effort to further understand the role of NK cells in combatting COVID-19, a group of researchers explored NK cells in acute viral infections, citing flavivirus and influenza virus infections as examples.

Novel ferritin nanoparticle vaccine candidate effective against SARS-CoV-2 variants in preclinical trials

A team of scientists from the United States has recently evaluated the efficacy of a ferritin nanoparticle-formulated, SARS-CoV-2 spike-based vaccine against newly emerged Variants of Concern (VOCs).

Mouse-adapted SARS-CoV-2 and simian adenovirus vector advance COVID-19 vaccine research

A new preprint recently released on the bioRxiv* server describes the immunogenicity and protective potential of a novel adenovirus SARS-CoV-2 vaccine candidate against a form of the virus adapted to cause severe disease in mice. The findings show that this provides a useful mouse model for the study of new vaccines, in addition to demonstrating the protective efficacy of the current rhesus adenovirus vaccine candidate RhAd52.

Aberdeen researchers develop antibody tests to detect new Covid-19 variants

Antibody tests that can detect whether people have been exposed to new variants of Covid-19 have been developed by the University of Aberdeen, in collaboration with biotechnology group Vertebrate Antibodies Ltd and NHS Grampian.

Antibody combination REGEN-COV prevents symptomatic disease following SARS-CoV-2 infection

Researchers in the United States have demonstrated the effectiveness of early treatment with REGEN-COV™ at preventing symptomatic disease among people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Corticosteroids may effectively treat children who develop a serious disorder after COVID-19

Corticosteroids may be an effective treatment for children who develop a rare but serious condition after COVID-19 infection.

'Wonder material' used to detect SARS-CoV-2 virus in laboratory experiments

Researchers at the University of Illinois Chicago have successfully used graphene -- one of the strongest, thinnest known materials -- to detect the SARS-CoV-2 virus in laboratory experiments.

COVID-e-Vax DNA vaccine candidate elicits robust immune responses in preclinical trials

A new study, released as a preprint on the bioRxiv* server, describes the late-stage clinical trial efficacy of a new vaccine candidate based on a deoxyribonucleic acid (DNA) plasmid platform expressing the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein. Among different constructs of the vaccine plasmid, the RBD was found to produce the most potent and broad immune response.

Study observes increased breadth of SARS-CoV-2 antibody neutralization acquired over one year

A new paper in the journal Nature offers a reassuring answer, showing that convalescent COVID-19 patients, some of whom had received vaccination as well, retain antiviral antibodies and neutralizing activity, as well as memory B cells, for up to 6-12 months from infection.

16 Jun 2021

Novavax COVID vaccine co-administered with flu vaccine appears safe and effective

Researchers from the UK recently reported the results of a sub-study that evaluates the safety, efficacy, and immunogenicity of the NVX-CoV2373 vaccine when co-administered with an approved seasonal influenza vaccine.

16 Jun 2021

Increased viral replication and shedding in nonhuman primates carrying SARS-CoV-2 B.1.1.7 variant

A team of researchers from the US and UK used the AGM intranasal model of SARS-CoV-2 infection to determine differences between a contemporary SARS-CoV-2 D614G variant circulating in summer 2020 and the B.1.1.7 UK variant of concern that emerged in late 2020.

Two vaccines elicit durable neutralizing antibody responses to SARS-CoV-2 in pre-clinical study

A group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate elicited durable neutralizing antibody responses to SARS-CoV-2 in pre-clinical research. There were no adverse effects.

SARS-CoV-2 oral vaccine booster shows promise in animal tests

In a recent study published on the pre-print bioRxiv* server, a group of Israeli researchers discusses their progress towards developing an oral multi-antigen SARS-CoV-2 vaccine.

New antibody testing study finds evidence of early COVID-19 infections in the U.S.

A new antibody testing study examining samples originally collected through the National Institutes of Health's All of Us Research Program found evidence of SARS-CoV-2 infections in five states earlier than had initially been reported.

15 Jun 2021

Study may offer an unexpected pathway for targeted treatment of brain tumors

In a new study led by Yale Cancer Center, researchers show the nucleoside transporter ENT2 may offer an unexpected path to circumventing the blood-brain barrier (BBB) and enabling targeted treatment of brain tumors with a cell-penetrating anti-DNA autoantibody.

15 Jun 2021

RBD and NTD antibody cocktail could prevent the emergence of SARS-CoV-2 escape mutants

A new bioRxiv* preprint demonstrates how a combination of antibodies to two different regions on the viral spike could enhance neutralization efficiency as well as prevent the emergence of resistant variants.

Fusogenicity and resistance of SARS-CoV-2 B.1.1.7 and B.1.351 compared to D614G

A new study, released as a preprint on the bioRxiv* server, describes the biological effects induced by mutations in two circulating VOCs. These are the alpha and beta strains, also called B.1.1.7 and B.1.351, respectively.

Potent antibodies against SARS-CoV-2 can be produced without T follicular helper cells, suggests study

It has been uncertain whether antibodies produced via this non-canonical pathway are protective against SARS-CoV-2. In a new study, recently released as a preprint on the bioRxiv*server, the neutralization potency of these antibodies is compared with those traditionally produced in germinal center-based antiviral responses.

REGEN-COV antibody cocktail shown to significantly lower SARS-CoV-2 viral load

In human trials, the interim analysis of 275 participants showed REGEN-COV quickly reduced viral loads. Moreover, this reduction was much faster in people who did not have a high viral load when they started treatment.
