Rosette inhibition levels during early human gestation

A W Thomson, J I Milton, D M Campbell

    Journal of Reproductive Immunology
    |December 1, 1980
    PubMed
    Summary

    Antilymphocyte globulin does not inhibit T cell rosette formation in early human pregnancy. T lymphocyte reactivity remains unimpaired during gestation and estrogen treatment.

    Area of Science:

    • Immunology
    • Reproductive Biology
    • Cellular Immunology

    Background:

    • Antilymphocyte globulin (ALG) is used in immunosuppression.
    • T cell rosette formation is a measure of T cell activity.
    • Pregnancy involves significant immunological changes.

    Purpose of the Study:

    • To investigate the effect of antilymphocyte globulin on T cell rosette formation during early human pregnancy.
    • To determine if T cell reactivity is altered during gestation.
    • To assess the impact of estrogen on T cell function.

    Main Methods:

    • Cross-sectional and longitudinal studies were conducted.
    • Peripheral blood T cells from pregnant women (10-21 weeks gestation) were analyzed.
    • Spontaneous rosette formation was measured in the presence of antilymphocyte globulin.

    Main Results:

    • No evidence of increased rosette inhibition by antilymphocyte globulin was found during early pregnancy.
    • T cell rosette formation levels were comparable to non-pregnant states.
    • Estrogen-treated women showed similar rosette formation values.

    Conclusions:

    • The intrinsic reactivity of human T lymphocytes is not impaired during human gestation.
    • Estrogen treatment does not significantly affect T cell rosette formation.
    • Immune responses in T cells remain robust during pregnancy.
