WebDec 18, 2024 · FcRn functions within intracellular endosomes, where it binds IgG and albumin at distinct, nonoverlapping sites under acidic but not neutral pH conditions . Thus, FcRn is considered a saturable “protection” receptor that serves to prevent the catabolism of IgG and albumin ( 8 ). WebApr 20, 2024 · Albumin has an average plasma half-life of three weeks and is thus an attractive carrier to improve the pharmacokinetics of fused therapeutics. The half-life is regulated by FcRn, a cellular ...
The neonatal Fc receptor: Key to homeostasic control of IgG
WebSep 1, 2024 · FcRn functions at 2 sites in the kidney (Fig 3, B). When expressed in podocytes of glomeruli, FcRn transcytoses IgG from the filtration membrane for delivery to the urinary space. 39, 52 IgG and IgG-ICs are too large to pass through the size-selective filtration of the kidney glomerulus into the urinary space. WebMar 23, 2024 · Among many functions, FcRn protects IgG from intracellular degradation and recycles it to the circulation. In the absence of FcRn catabolism of IgG is increased and the serum concentration of IgG decreases to levels similar to IgM or IgA. 1 Understanding the functions of FcRn has manifold implications to transplantation.
