fcRn

Neonatal Fc receptor ( FcRn ) is the receptor which can identify fragments of immunoglobulin IgG Fc .

新生儿Fc受体（FcRn）是识别免疫球蛋白IgGFc片段的特异性受体。

The neonatal Fc receptor ( FcRn ) can mediate mucosal polarized epithelial cells to transport IgG initiatively by binding specific IgG Fc fragments , thus allowing body to obtain the ability to resist pathogens .

FcRn可特异性的结合IgGFc片段，介导黏膜上皮细胞主动转运IgG，使机体获得抵御病原体的能力。
