【 摘 要 】

In mammals, immune tolerance against fetal tissue has been established for normal pregnancy progression. It is known that Crry regulates complemental activity to prevent injury of the mouse embryo and extra-embryonic tissue. This study aimed to examine the expression appearance and normal localization sites of Crry in the mouse placenta. Also, the emergency responses of Crry were verified at the time of experimental miscarriage induction. Moreover, we investigated an existing similar protein of Crry in animal placentas other than mice. Crry expression level showed a peak at day 8.5 of pregnancy. Trophoblast giant cells and decidual cells indicated a positive reaction to anti-Crry antibody. After treatments of interferon-γ, Crry expression was increased significantly in the survived implantation sites as compared with the controls. However, there was no significant difference in the miscarriage-initiated sites. It disclosed that Crry distributes from the early to middle periods of the placentas and involves complement regulation at the extraembryonic tissue and decidua basalis. Crry also showed an ability to respond to risk against external initiation for urgent miscarriage. Finally, we found anti-mouse Crry antibody-bound proteins in the placenta of many animals. It suggests a potency of Crry to make an environment of immune tolerance in many types of mammal placentas.
