Abstract/OtherAbstract:
Abstract Objectives: To establish gender-specific differences in maternal and fetal immune response in healthy human fetuses at term. Methods: Forty-five women with elective caesarean sections for uncomplicated singleton pregnancies were recruited for two studies. Using a Multiplex Biomarker Immunoassay system, un-stimulated maternal and fetal plasma concentrations of IL-1β, IL-1ra, IL-6, IL-8, MIP-1α, and TNF-α were measured from one study population. LPS-stimulated cytokine response was measured in a second study. Results: There were no significant gender differences in either maternal or fetal un-stimulated plasma cytokine concentrations, but concentrations of the pro-inflammatory cytokines IL-1β and IL-6 were significantly greater in male fetal LPS stimulated samples than in female fetal samples. Conclusions: Blood of male fetuses mounts a larger pro-inflammatory response to LPS. This heightened response could be a critical pathway in promoting PPROM and may be associated with life long differential gender response to infection.
