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.

Researchers develop novel antibody fragments against SARS coronavirus-2

An international research team led by the University of Bonn (Germany) has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

Scientists identify sensor in human lungs that detects SARS-CoV-2

Scientists at Sanford Burnham Prebys Medical Discovery Institute have identified the sensor in human lungs that detects SARS-CoV-2 and signals that it's time to mount an antiviral response.

Antibody-Fc-mediated innate immunity shapes COVID-19 severity

A short paper that appeared recently on the preprint bioRxiv server pointed to a link between specific characteristics of anti-SARS-CoV-2 antibodies associated with the severity of COVID-19.

Intranasal vaccination effectively reduces viral shedding of SARS-CoV-2 in monkeys

A new preprint that appeared on the bioRxiv server reports that intranasal vaccination with the D614G variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in rhesus monkeys reduces viral shedding. This is an experiment in non-human primates (NHP), and its extrapolation to humans is unclear as yet.

Effect of mutations in the South African SARS-CoV-2 variant on transmission and neutralization

One such strain is the South African 501.V2 and UK B1.1.7 strains, which have been isolated from many countries and seem to spread faster than the ancestral strain. A preprint that recently appeared on the bioRxiv server reports the computational structure of this strain and the possible effect of the mutations on infectivity and neutralization.

Researchers discover a new approach to inhibit intrahepatic cholangiocarcinoma

Reprogramming the rich connective tissue microenvironment of a liver cancer known as intrahepatic cholangiocarcinoma (ICC) inhibits its progression and resistance to standard chemotherapy in animal models, researchers from Massachusetts General Hospital have found.

Antigenic "supersite" could improve design of COVID-19 vaccines

Researchers in the United States have defined an antigenic “supersite” within the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could have important implications for the design of vaccines to protect against coronavirus disease 2019 (COVID-19).

Nanobodies have potential to be developed into a treatment for COVID-19

Researchers at Karolinska Institutet in Sweden have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells.

Advanced humanized mouse model helps better understand immunotherapy resistance in melanoma

Scientists at The Wistar Institute have created an advanced humanized immune system mouse model that allows them to examine resistance to immune checkpoint blockade therapies in melanoma. It has revealed a central role for mast cells. These findings were published today in the journal Nature Communications.

OXGENE introduces SLIM platform for discovery of antibodies against membrane proteins

OXGENE™ announces the introduction of its self-labelling integral membrane (SLIM™) protein discovery system.

Study investigates effect of anti-CD45 RIT lymphodepletion on immune cell types

Oncotarget recently published "Targeted lymphodepletion with a CD45-directed antibody radioconjugate as a novel conditioning regimen prior to adoptive cell therapy" which reported that Chimeric antigen receptor T cell therapies, and adoptive cell therapy in general, represent one of the most promising anti-cancer strategies.

Discovery of SARS-CoV-2 neutralizing antibodies from a naïve human Ab library

Now, a new preprint research paper published on the bioRxiv server shows how closely the antibodies formed in exposed humans resemble the germline antibody molecules. This could lead to the development of novel therapeutics to counter the pandemic.

SARS-CoV-2 exposure in England could be double reported seroprevalence

A new study that recently appeared on the preprint server medRxiv* makes use of a combined method to estimate population exposure to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), taking into account the fact that patients who recover from the infection often do not have circulating antibodies against the virus.

The mystery of Giglio island’s resistance to COVID-19

An intriguing new study explores the mechanisms by which an Italian island called Giglio remained resistant to coronavirus disease 2019 (COVID-19) even after much exposure.

Study supports continuing phase 3 trials of Ad26.COV2.S SARS-CoV-2 vaccine

An international team of researchers has provided further evidence to confirm the immunogenicity and efficacy of a recombinant adenovirus vaccine currently being tested in phase 3 trials for its ability to protect against infection with severe acute respiratory coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Antibody recognition of linear SARS-CoV-2 epitopes preserved in mutated B.1.1.7 strain

In a recent medRxiv research paper, the US scientists examined the effects of non-synonymous mutations in the circulating B.1.1.7 strain of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on linear antibody epitope signal for viral spike glycoprotein and nucleoprotein – and demonstrated that mutations should not result in immune evasion.

Trinity researchers discover key mechanism underlying bacterial skin colonization in atopic dermatitis

Researchers from Trinity College Dublin have discovered a key mechanism underlying bacterial skin colonization in atopic dermatitis, which affects millions around the globe.

Sustained immune response memory detected in recovered COVID-19 patients

A team of researchers at the University of Washington School of Medicine has found that people who had mild COVID-19 developed a multi-layered immune response against SARS-Cov-2. The researchers detected neutralizing antibodies against the virus for at least three months after recovering from the infection.

Vimentin could be a major co-factor that aids SARS-CoV-2 infection

A recent study has found that extracellular vimentin can bind to SARS-CoV-2 spike protein in vitro, and antibodies against vimentin can decrease virus infectivity by up to 80%. This suggests vimentin could aid the virus’s binding to host cells and help in infection.

Seroprevalence and asymptomatic carrier status of SARS-CoV-2 in China

As asymptomatic transmission chains play a role in SARS-CoV-2’s viral spread, a new study by researchers in Wuhan, China, investigated the seroprevalence and asymptomatic carrier status of SARS-CoV-2 in the region.
