    Summary

    This study assessed maternal and fetal lymphocyte responsiveness to various stimuli. The results demonstrate that lymphocyte transformation assays are reproducible and reliable for detecting significant immune responses.

    Area of Science:

    • Immunology
    • Cellular immunology
    • Maternal-fetal immunology

    Background:

    • Assessing maternal and fetal immune responses is crucial for understanding pregnancy outcomes.
    • Lymphocyte transformation assays are a key method for evaluating cellular immunity.

    Purpose of the Study:

    • To evaluate the in vitro responsiveness of maternal and fetal lymphocytes to a range of mitogens and antigens.
    • To determine the reproducibility and reliability of lymphocyte transformation assays in maternal-fetal pairs.

    Main Methods:

    • Examined lymphocytes from 107 maternal-fetal pairs for in vitro responsiveness.
    • Stimulated lymphocytes with phytohaemagglutinin (PHA), candida, varicella, mumps, streptokinase-streptodornase (SKSD), and tetanus toxoid.
    • Analyzed data using the difference between square roots of isotope incorporation in stimulated and control cultures, with experimental errors ranging from 1.0% to 16.6%.

    Main Results:

    • Lymphocyte transformation assay data were reproducible across two sequential groups of participants.
    • Statistical analysis confirmed reproducibility in 48 out of 56 analyses.
    • Established statistical limits for stimulation or suppression based on analysis of variance.

    Conclusions:

    • Lymphocyte transformation assays provide a reproducible and reliable method for assessing maternal and fetal immune responses.
    • The technique can reliably detect significant differences from control values in lymphocyte responsiveness.
