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… WebAug 15, 2024 · (Playback ID: VBkEl_GEZzIZhpnP) Learn More A really important component of IgG antibodies is their ability to have a really long half-life in circulation, as …
