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.

Faulty genes and an autoimmune condition linked to severe COVID-19 in young, healthy people

More than 10 percent of young and healthy people who develop severe COVID-19 have misguided antibodies that attack not the virus, but the immune system itself, new research shows. Another 3.5 percent, at least, carry a specific kind of genetic mutation.

Berlin researchers are pursuing the development of passive vaccination

Researchers at the German Center for Neurodegenerative Diseases (DZNE) and Charité - Universitätsmedizin Berlin have identified highly effective antibodies against the coronavirus SARS-CoV-2 and are now pursuing the development of a passive vaccination.

New material identifies cancer cells and mounts a surprising attack

Many people across the globe are working hard to get the better of cancer; however cancer is always working too. Cancer cells can become resistant to the methods that have been adopted to kill them, so identifying drugs that act in different ways is part of the push to outsmart this ubiquitous disease

A possible inverse relationship between Dengue and COVID-19 in Brazil

Their study titled, “How super-spreader cities, highways, hospital bed availability, and dengue fever influenced the COVID-19 epidemic in Brazil,” was released pre-peer review on the preprint medRxiv* early this week.

Prevalence of SARS-CoV-2 with D614G mutation in a second wave infection in Houston

A recent study reveals that the genetic variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detected in the initial phase of coronavirus disease 2019 (COVID-19) pandemic differ from the variants detected in a massive second wave of infection in Houston, Texas. The study is currently available on the medRxiv preprint server.

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Research says in SARS-CoV-2 canine infection, transmission unlikely

A new study published on the preprint server bioRxiv* in September 2020 shows that pet dogs have been falling sick and dying of a mysterious respiratory infection, often showing the presence of anti- severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies, even though in many cases they do not test positive for COVID-19.

Brazil becomes global hotspot for COVID-19 pandemic

Two nationwide COVID-19 antibody seroprevalence studies from Brazil show that many cities along the Amazon were hit hardest at the beginning of the epidemic in May and June, along with poorer and Indigenous communities.

FDA issues emergency use authorization for first serology point-of-care test for COVID-19

Today, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) for the first serology (antibody) point-of-care (POC) test for COVID-19.

Siemens’ SARS-CoV-2 antibody immunoassays meet regulatory targets

New research being presented at the ESCMID Conference on Coronavirus Disease (ECCVID, online 23-25 September) shows that, in a head-to-head comparison of five tests used to detect SARS-CoV-2 antibodies (known as 'immunoassays'), an assay manufactured by Siemens and one developed by an academic partnership led by the University of Oxford had the most accurate results.

NeutrobodyPlex nanobodies help monitor SARS-CoV-2 immune responses

Researchers recently described a set of 11 Nbs derived from an immunized alpaca which showed high-affinity binding to the glycosylated SARS-CoV-2 spike receptor domain (RBD) in a study published in the preprint server bioRxiv.

Fourth Phase 3 clinical trial evaluating COVID-19 vaccine begins in the U.S.

A fourth Phase 3 clinical trial evaluating an investigational vaccine for coronavirus disease 2019 (COVID-19) has begun enrolling adult volunteers.

Dextran sulphate-induced tau assemblies cause tau propagation in non-transgenic mice

Accumulation of assembled tau protein in the central nervous system is characteristic of Alzheimer's disease and several other neurodegenerative diseases, called tauopathies.

Study on domestic cats and dogs in COVID-19+ households

A recent survey conducted by a team of scientists from France reveals that pets living with confirmed coronavirus disease 2019 (COVID-19) patients have a high prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. The study is currently available on the bioRxiv* preprint server.

Children exhibit distinct immune system responses against COVID-19

Children and adults exhibit distinct immune system responses to infection by the virus that causes COVID-19, a finding that helps explain why COVID-19 outcomes tend to be much worse in adults, researchers from Yale and Albert Einstein College of Medicine report Sept. 18 in the journal Science Translational Medicine.

Molecular dynamic simulations reveal detailed spike-ACE2 interactions

The current COVID-19 pandemic has spread throughout the world. Caused by a single-stranded RNA betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is closely related to but much more infectious than the earlier highly pathogenic betacoronaviruses SARS and MERS-CoV, has impacted social, economic, and physical health to an unimaginable extent.
