In the introduction, we briefly recall old but classic evidence that there is no tolerance to paternal alloantigens in a first pregnancy. Therefore, we performed small- and largescale microarrays in CBA×DBA/2 and CBA×BALB/c combinations, recently described as a murine model for preeclampsia. Our results are in line with other data suggesting a very early deregulation of local immune vascular events rather than a break of immune tolerance. Other data presented at the Tioman 2010 Preeclampsia Workshop supporting this hypothesis are briefly summarised, as well as indications and caveats from a recent human microarray on implantation failure and recurrent pregnancy loss.
