Multiple autoimmune disorders are caused by the binding of IgG to self antigens. Since FcRn extends IgG half-life in the circulation, it can also confer long half-lives on these pathogenic antibodies and promote autoimmune disease. Therapies seek to disrupt the IgG-FcRn interaction to increase the clearance of disease-causing IgG autoantibodies from the body. One such therapy is the infusion of intravenous immunoglobulin (IVIg) to saturate FcRn's IgG recycling capacity a… WebNov 10, 2024 · Mechanism of FcRn to prolong the half-life.

WebDec 1, 2013 · Albumin has an extraordinarily long circulatory half-life. Albumin's half-life results from its size and interaction with an FcRn mediated recycling pathway. Albumin is used to extend the circulatory half-life of drugs. Drugs can be engineered to bind to albumin, are conjugated to or are genetically fused to albumin. WebAug 15, 2024 · FcRn concentrations across 14 human tissues ranged from low to 230 pmol per gram of tissue. Furthermore, the FcRn half-life was determined to be 11.1 h from a human stable isotope labelled leucine pulse labeling experiment.
Webis weak at neutral pH so that it can be recycled. Decreasing the affinity to FcRn reduces the serum half-life which is advantageous if the antibody is used for diagnostic tests or for controlling toxicity (4). In vitro FcRn binding assays have been used to measure changes in FcRn binding after introduction of various mutations. High-Throughput ...
