Abstract: The present application discloses use of FcgammaRIIB as an IgG transport receptor in mammary gland of mammals, and belongs to the field of biotechnology. FcgammaRIIB knockout mice and FcgammaRIIB knockout pigs are constructed, and the ratio of mammalian serum IgG to milk IgG in the FcgammaRIIB knockout mice is significantly increased, indicating a decrease in relative milk IgG concentration. Although mammalian serum IgG content is significantly increased in the FcgammaRIIB knockout pigs, IgG in colostrum of mammals is nearly undetectable. Therefore, the present application demonstrates for the first time that FcgammaRIIB serves as the receptor mediating transport of mammalian serum IgG across the mammary epithelial barrier into milk, which addresses a long-standing unresolved issue in the field of maternal passive immunity. Furthermore, the present application provides a new strategy for increasing colostrum IgG content, thereby enhancing early immunity and survival rate of newborn livestock.
