- Abstract
Pregnancy is a temporary semi-allograft that survives for nine months. The importance of this event for the survival of the species justifies several tolerance mechanisms that are put into place at the beginning of pregnancy, some of which occur even at the time of implantation. The description of these mechanisms underlines the leadership of the trophoblast. The trophoblast is the conductor of the events, protects himself by expressing specific antigens and regulates the environment of the decidua according to the calendar of the events of the pregnancy The trophoblast and the decidual environment attract the effectors of immunity, almost all present in the decidua. The immunological atmosphere of the decidua evolves during the pregnancy modulating the level of activation of the immunological cells and adapting the level of activation to the stage of the pregnancy., (Copyright © 2014 Elsevier Masson SAS.
