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 ...

Deleting a single amino acid (Pro230) in the lower hinge produced half-IgG1 molecules with disrupted disulfide bonds and reoriented Fab and Fc regions, highlighting the hinge’s essential role in ...

Vertebrates with a defined immune system, such as humans, have an immune response consisting of an innate and adaptive response, also known as a specific response. The specific response is tailored to ...
