Modulation of nonspecific cell-mediated growth inhibition by estrogen metabolites.
    Immunopharmacology, 1985, Volume: 10, Issue:2

    Chronic exposure of mice to estrogens such as 17-beta estradiol and diethylstilbestrol inhibits natural killer cell-mediated cytotoxicity in vivo. In this report, we investigated the direct in vitro effects of 17-beta estradiol and its major metabolites on nonspecific effector cell function measured as the ability of naive lymphocytes to inhibit the growth of the YAC-1 lymphoma, a classical natural killer-sensitive target cell. Without exception, the effects of individual estrogen metabolites on the growth inhibitory properties of these cells were accompanied, at every concentration of compound, by identical effects on the blastogenic response of lymphocytes to the T cell lectin phytohemagglutinin. These observations suggested membrane-mediated immunomodulation of lymphocyte function by estrogen metabolites. As suggested by previous studies with quinone metabolites of benzene, the catechol estrogen metabolite 2-OH estrone was significantly more potent than the parent compound at suppressing lymphocyte functions in vitro; however, dosing regimens of 2-OH estrone that suppressed blastogenic response in vivo failed to inhibit nonspecific cell-mediated growth inhibition.
