Angiogenesis factors (VEGF, Ang-1, TGF-β) influence production, development and functioning of vascular endothelium that are part of the placental barrier structure and are involved into transplacental transfer of different substances. The aim of this study was to study the relationship between VEGF, Ang-1, and TGF-β concentrations, and the levels of transplacental IgG-antibodies to the measles virus in cord blood of children born to mothers with placental insufficiency. Patients and methods: venous blood was taken from 32 women with uncomplicated pregnancies, and 34 samples from pregnant women with placental insufficiency, as well as umbilical blood of their newborns, the level of IgG-antibodies to measles and the concentration of some angiogenic factors (VEGF, Ang-1, TGF-β) examined by ELISA techniques. The following results were obtained: in a cord blood of infants seronegative for the measles virus, born to women with placental insufficiency, showed uniformly low VEGF levels, decreased Ang-1 concentration (1.6) and increased TGF-β concentration (2.7) as compared to seropositive newborns. In a similar group of children from mothers with physiological pregnancy, the level of these factors did not differ from those in newborns with protective antibodies to measles. Conclusion: in physiological pregnancy, transplacental transmission of IgG-antibodies to the measles virus is directly dependent on the presence of specific antibodies in a woman; in case of placental insufficiency, an imbalance in the system of angiogenic factors may promote disturbances of transmission mechanisms for IgG measles-specific antibodies from mother to the fetus.
