英文摘要
To clarify the physsiological and pathological roles of inflammation system in placenta during pregnancy, we investigated the roles of CD1d antigen on trophoblasts and of lysophosphatidic acid (LPA) system in placenta. The decrease of CD1d expression on cytotrophoblasts with extravillous trophoblast (EVT) differentiation was induced via transforming growth factor (TGF)-・ secretion by trophoblasts. β_2-glycoprotein I (β_2GPI)-dependent anti-phospholipid antibody induced interleukin-12 release from trophoblasts via recognition of β_2GPI bound to phosphatidylserine on CD1d on trophoblasts, which might cause pregnancy loss via inflammatory mechanism.Trophoblasts expressed the major lysophosphatidic acid (PLA) producing enzyme, autotaxin (ATX). RNA amounts of ATX in placenta tissues increased with gestational weeks. The serum concentration of ATX protein was higher in patients with preterm labor than that in normal pregnant women. These results suggest the physiological roles of its bioactive resultant substance, LPA, during pregnancy.
