In a recent study posted to the bioRxiv* pre-print server, researchers investigated the complement component 1q (C1q) binding and subsequent complement activation by neutralizing antibodies (nAbs) ...

A new University of Manchester and Edinburgh study published in the journal Brain, Behavior and Immunity has found that ...

Many vaccines work by introducing a protein to the body that resembles part of a virus. Ideally, the immune system will produce long-lasting antibodies recognizing that specific virus, thereby ...

Birds produce a form of antibody, IgY, found in eggs. UC Davis researchers have shown that quantities of IgY antibody specific for the COVID-19 virus spike protein can be produced from eggs by ...

A new study using serum from human blood samples suggests neutralizing antibody levels produced by two-dose mRNA vaccines against the original and early variants of the SARS-CoV-2 virus wane ...

Children infected with SARS-CoV-2 are less likely than adults to produce antibodies against the virus, despite having similar symptoms and levels of virus in their bodies, according to a small study ...

Scripps Research scientists found that HIV vaccination can lead to the production of anti-immune complex antibodies (blue) that recognize immune complexes composed of antibodies (green) rather than ...

The Journal of Immunology reports that vaccination of neonatal mice with group A Streptococcus promoted a clonal expansion of innate-like B cells that produce antibody against N-acetyl-D-glucosamine, ...
