[Immunosuppressive factors of placental blood serum].
The action of soluble factors responsible for the immuno-suppressive effect of placental blood serum and placental extracts has been analyzed. It has been shown that fetoplacental proteins, trophoblastic antigens, antibodies to histocompatibility antigens, receptors to Fc-fragments of IgG participate in the realization of immunosuppression during pregnancy. Data have been presented on the possibility of using immunosuppressive properties of placental blood for production of a gamma-globulin immunomodulating preparation.
