Quizplus · Accepted Answer

Neonatal immunity is mediated in part by antibodies in breast milk,which are absorbed in the gastrointestinal tract by specific Fc receptors.These receptors are specific for the IgG isotype and are called FcF1F1F1S1F1F1F10RN (N for "neonatal").Absorption of antibodies from the mother's breast milk is a primary mode of immunity for the first 6 months of life,before the infant has produced significant amounts of antibody on its own.
