Effect of estrogens on the myeloperoxidase-mediated antimicrobial system

Abstract

Estradiol 17 beta prevented the fall in the microbicidal activity of the myeloperoxidase-H2O2-halide system induced by high H2O2 concentrations. In contrast, when the H2O2 (and halide) concentrations were low the myeloperoxidase-H2O2-halide antimicrobial system was inhibited by estradiol. These properties of estradiol 17 beta were shared by estradiol 17 alpha, estrone, estriol, ethinyl estradiol, and phenol, but not by estradiol-3-benzoate, testosterone, progesterone, hydroxyprogesterone, cortisone, hydrocortisone, or deoxycorticosterone.
