MHC, Major Histocompatibility Complex Although studies with early β2‐microglobulin deficient mice and humans with mutations in β2‐microglobulin confirmed that FcRn was essential for the long half‐life of IgG, this deficiency altered many additional immunological parameters related to MHC class I · Oral delivery of single chain and heterodimer FSH–Fc Neonatal rats were given a single oral dose (03 mg/kg) of single chain or heterodimer FSH–Fc Blood was collected at various times after administration, and serum levels of each protein measured with an FSH/Fc sandwich ELISA n=4/timepointThe neonatal Fc receptor (FcRn), also known as the Brambell receptor and encoded by Fcgrt, is a MHC class I like molecule that functions to protect IgG and albumin from catabolism, mediates transport of IgG across epithelial cells, and is involved
Introduction It was F W Rogers Brambell who first proposed the idea of a fragment crystallizable (Fc) receptor system for Immunoglobulin G (IgG) after investigating the passage of maternal antibodies to fetuses and neonates ()However, the identity of the specific receptor mediating this transfer, the neonatal Fc receptor (FcRn), remained unknown for nearly 30 more years by which„neonatal" bezieht sich auf das Vorkommen und der erstmaligen Isolation des Rezeptors aus dem Darm neugeborener Ratten durch Jones und Waldmann (Jones & Waldman 1972, Junghans 1997) Junghans schlug darüber hinaus FcRB (= BrambellRezeptor) zu Ehren des Erstbeschreibers des Rezeptors, Francis WilliamCareful regulation of the body's immunoglobulin G (IgG) and albumin concentrations is necessitated by the importance of their respective functions As such, the neonatal Fc receptor (FcRn), as a single receptor, is capable of regulating both of
