Lower hinge of immunoglobulin G controls immune activity and antibody stability

news-medical.net

The lower hinge of immunoglobulin G (IgG) acts as a critical immune control hub, according to new research. A single amino acid deletion in this region transforms a full-length antibody into a stable half-IgG1 molecule with altered immune activity, offering a blueprint for next-generation antibody therapies. This discovery highlights the lower hinge's decisive role in antibody shape, stability, and function, potentially enabling customized therapeutic effects for diseases like cancer.
