Abstract
In this brief sub-chapter we review first quickly pregnancy specific proteins (which were at the time seen in a context of general dampening of maternal immune response) to discuss then anergy inducing placental factors and exosomes. We finish by dealing with placenta integrated retroviruses, and their immunosuppressive properties.
