    The mixed lymphocyte culture (MLC) of maternal and newborn (cord) cells is significantly weaker than that of father-newborn and control-newborn cultures. This hyporeactivity was found not to be due to an impaired function or tolerance of either the maternal or neonatal cells. We investigated the possibility that a specific, in vivo-induced suppressor cell was active in the diminished maternal-newborn reaction. Suppressor cells were found to be active in both the stimulating and responding populations in the unidirectional MLC. The removal of TG cells from the responding (maternal or newborn) population resulted in an increase of reactivity specific for the corresponding stimulating population (newborn or maternal). The suppressor activity within the stimulating population was carried out by a radiosensitive cell, which did not require proliferation to exert its effect. We suggest that the observed hyporeactivity of maternal-newborn mixed lymphocyte cultures is due to the modulation of the reaction by specific, in vivo-induced suppressor cells.

    Transcytosis of IgG01:15

    Transcytosis of IgG

    Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
    IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

    Gonadal and Placental Hormones

    The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
    In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

    Development of Immunocompetence

    The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
    The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
    Subsequent T...
