Outline of Final Research Achievements

Fetal Inflammatory Response Syndrome (FIRS) develops when inflammation extends to the amnion and the umbilical cord in chorioamnionitis. The survival rate is reported to increase in experimental animals with sepsis as a result of the administration of an activin binding protein which negates the activity of activin. Therefore, we studied the effects of inflammatory cytokines on the synthesis of activin and negative regulators of activin in human amniotic cells. Inflammatory cytokines predominantly stimulated the synthesis of activin compared to that of negative regulators of activin. Some of the signal transduction pathways involved in increased activin synthesis by the inflammatory cytokine TNF-alpha were also elucidated in this study. From these results, the inhibition of the synthesis of activin in human amniotic cells and the administration of negative regulators of activin appear to be exploitable for the development of a new FIRS therapy.
