Antibodies are proteins with around 150 kDa molecular weight. They have a similar basic structure comprising of four polypeptide chains held together by disulfide bonds. These four polypeptide chains ...

Antibodies in the gut target and control pathogenic infection, but they also target common resident commensal microorganisms. This suggests that immunoglobulins might influence microbiota composition ...

Antibodies are immune proteins that our bodies produce to help fight off infection. Where they recognize and bind a pathogen — and how — can give important clues to the microbe’s vulnerabilities. Fred ...

Scientists at Fred Hutchinson Cancer Research Center in Seattle have shown that a potent antibody from a COVID-19 survivor interferes with a key feature on the surface of the coronavirus’s distinctive ...

Antibodies, also known as immunoglobulins, are specialized proteins produced by the immune system to identify and neutralize foreign invaders, such as viruses, bacteria, and other pathogens. They are ...

The lower hinge of immunoglobulin G (IgG), an overlooked part of the antibody, acts as a structural and functional control hub, according to a study by researchers at Science Tokyo. Deleting a single ...

From penetrating solid tumors to new success rates for de novo design, the next wave of antibody therapies aims to transform the clinic.

A bacteria-only sugar has become the Achilles’ heel that could help defeat deadly superbugs.

Three years into the Covid-19 pandemic, it is clear that some of us produce stronger immune reactions to infection than others. Some may only experience mild flu-like symptoms, while others could be ...
