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.

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.

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).

3 May 2021

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.

Cell-free DNA tests can reduce the need for biopsies to detect rejection after heart transplant

A new study, presented today at the AATS 101st Annual Meeting, shows that non-invasive cell-free DNA tests can reduce the need for regular surveillance biopsies to detect early rejection in heart transplant patients. The study was the first of its kind to be performed on both adult and pediatric patients.

Single dose of vaccine boosts protection only in people previously infected by COVID-19

A single dose of vaccine boosts protection against SARS-CoV-2 coronavirus variants, but only in those with previous COVID-19, a study has found.

Human to animal transmission of SARS-CoV-2 in households is common

Coronaviruses are seen in multiple mammalian species. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the COVID-19 pandemic, is said to have passed to humans from a mammalian source and to have originated from an animal reservoir as a zoonotic pathogen.

Monoclonal antibody CT-P59 shows preclinical efficacy against South African SARS-CoV-2 variant

Researchers in the Republic of Korea (South Korea), The Netherlands, and South Africa have demonstrated the potential of the monoclonal antibody CT-P59 as an effective therapeutic for coronavirus disease 2019 (COVID-19) caused by the South African B.1.351 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Guidance on diagnosis and management of cerebral venous sinus thrombosis after a COVID-19 vaccine

Last Friday, the Centers for Disease Control and Prevention and the U.S. Food & Drug Administration lifted the pause in administration of the Johnson & Johnson (Janssen) COVID-19 vaccine in the U.S.

29 Apr 2021

Researchers characterize a large set of therapeutic antibodies against SARS-CoV-2 variants

A team of scientists from A-Alpha Bio., USA, has recently conducted a large-scale screening of 33 therapeutic antibodies to examine their binding affinity to a number of SARS-CoV-2 variants. The team analyzed the impact of potential mutations in the spike RBD on antibody efficacy.

29 Apr 2021

Host protein mimicry of SARS-CoV-2 receptor binding motif

In a new study, structural bioinformatics approaches are employed to investigate the potential mimicry of the receptor-binding motif (RBM) of these three coronaviruses, finding that several proteins from both human and non-human sources were similar to each, with implications regarding the mechanism of infection and tropism of SARS-CoV-2.

New insights into how South African SARS-CoV-2 variant sacrifices tight binding for antibody evasion

The highly infectious SARS-CoV-2 variant that recently emerged in South Africa, known as B.1.351, has scientists wondering how existing COVID-19 vaccines and therapies can be improved to ensure strong protection.

Study of 180 breastfeeding mothers after mRNA COVID-19 vaccination

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, were developed at an unprecedented pace. To date, more than 1 billion vaccine doses have been administered worldwide, many of which messenger RNA (mRNA) based.

29 Apr 2021

Potent monoclonal antibody shows promise against emerging SARS-CoV-2 variants of concern

In a new study currently available on the bioRxiv* preprint server, a group of US-based researchers developed a panel of neutralizing monoclonal antibodies against SARS-CoV-2 that can block viral attachment to cells – and pinpointed a specific one that can potently neutralize all tested variants of concern.

28 Apr 2021

Recovered COVID-19 patients show signs of long-term immunity

A study conducted by researchers in the United States has found that most patients who recovered from coronavirus disease 2019 (COVID-19) showed signs of long-lasting immunity against the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Nanobodies may be the key to blocking tick-borne bacterial infection

Tiny molecules called nanobodies, which can be designed to mimic antibody structures and functions, may be the key to blocking a tick-borne bacterial infection that remains out of reach of almost all antibiotics, new research suggests.

28 Apr 2021

Study examines mRNA COVID-19 vaccine’s effectiveness across age and gender

The findings reveal that although the two-dose vaccine regimen initially induces robust antibody response in all age groups, older male individuals are particularly associated with a gradual decline in vaccine-induced immunity six weeks after the second vaccine dose.
