WebJun 26, 2024 · IgG half-life is primarily regulated by binding to the neonatal Fc Receptor, FcRn, through the IgG’s constant region, Fc. This Fc-FcRn binding occurs in the acidic lysosome of endothelial cells and rescues …

WebThe neonatal Fc receptor (FcRn) plays a key role in prolonging the serum half-life of IgG. Antagonizing FcRn to prevent its binding to IgG can accelerate the catabolism of the latter, resulting in decreased levels of IgG, including pathogenic autoantibodies, thereby achieving a therapeutic effect. In this review, we detail the substantial ... WebNov 10, 2024 · Mechanism of FcRn to prolong the half-life IgG has a half-life of up to 2 to 4 weeks in the human body.
