This study examined the occurrence of placental C-reactive protein (CRP) in normal pregnancy with term delivery, spontaneous preterm delivery (sPTD), preeclampsia, and miscarriage. CRP immunoreactivity was detected in the syncytiotrophoblast. The immunopositive rate was significantly higher in sPTD than preeclampsia. The CRP immunopositive rate was also higher in acute chorioamnionitis than those without and showed a good correlation with the maternal serum CRP concentration. CRP mRNA expression was not detected in human and mouse placentas or choriocarcinoma cells. CRP may play a role in the pathological and physiological states of pregnancy.
