| * The first diagram (entitled Transfer of [[Immunoglobulin G|IgG]] across intestine via FcRn) shows [[Immunoglobulin G|IgG]] being present in the intestine of a neonate, from the ingestion of colostrum. Fc receptors (FcRn) are present on the surface of the intestinal epithelial cell in neonates for the first 30 hours. The [[Immunoglobulin G|IgG]] binds to the receptors and is transported through the cell by pinocytosis and released into the lacteals unchanged. | | * The first diagram (entitled Transfer of [[Immunoglobulin G|IgG]] across intestine via FcRn) shows [[Immunoglobulin G|IgG]] being present in the intestine of a neonate, from the ingestion of colostrum.
