| Outline of Final Research Achievements |
Maternal hypercytokinemia associated with preterm labor induces fetal inflammatory response syndrome (FIRS) and increases the risk of neonatal complications. The association between preterm labor and decidual macrophages of maternal origin has been reported. However, the association between preterm labor and placental chorionic macrophages of fetal origin remains unknown. This study examined the involvement of phenotype of chorionic macrophages in the neonatal outcome associated with FIRS. The immunohistochemical analysis revealed that the number of anti-inflammatory macrophages in the placental chorionic villi was significantly decreased in preterm newborn diagnosed with periventricular leukomalacia (PVL) or chronic lung disease (CLD). The increased number of inflammatory macrophages in the chorionic villi may be associated with the pathogenesis of PVL or CLD.
