母体产生的可向胎儿移行的抗体为IgG类抗体,胎盘细胞有IgG的FC段受体,从细胞中摄取后通过胎盘向胎儿移行,在胎儿血或胎儿组织中引起免疫反应,导致细胞减少或自身免疫性疾病。母体所产生的抗体包括血型抗体和自身免疫性疾病的自身抗体,血型抗体有抗红细胞抗原的抗体,抗血小板抗 The maternally generated antibody that migrates to the fetus is an IgG-like antibody and the placental cells have an Fc fragment of IgG that is taken up from the cell and passed through the placenta to the fetus, causing an immune response in the fetus’s blood or fetal tissue, resulting in a reduction or Autoimmune diseases. Antibodies produced by the maternal include autoantibodies of blood group antibodies and autoimmune diseases, antibodies of blood group antibodies having anti-erythrocyte antigens, anti-platelet antibodies
