The Fc Receptor FcRn, Expressed in Intestinal Epithelial Cells, Binds

question 22

Essay

The Fc receptor FcRn, expressed in intestinal epithelial cells, binds to the Fc portion of IgG antibodies. Moreover, FcRn binds to IgG with high affinity at an acidic pH (<6.5) but not at physiological pH (pH 7.4). How is this biochemical feature of FcRn critical for its role in antigen presentations for gut immunity?
