title: Secretion of proinflammatory cytokines by villous chorion tissue in spontaneous abortion.
abstract: Secretion of proinflammatory cytokines IL-1 beta, TNF-alpha, IL-6, IFN-alpha, and IFN-gamma by the chorion tissue (8-12 weeks) was studied in normal gestation and spontaneous abortion. The production of IL-1 beta, TNF-alpha, and IFN-alpha virtually did not change in spontaneous abortion, while IFN-gamma was not secreted in all experimental groups. The production of IL-6 increased more than 2-fold in patients with spontaneous abortion during the first trimester. These data confirm the involvement of this cytokine in the reproductive processes and in the pathogenesis of miscarriage.
