There is growing evidence that pregnancy complications such as preeclampsia, recurrent pregnancy loss (RPL), IUGR, and premature birth could be associated with abnormal immunologic interactions at the fetal-maternal interface. The restricted expression of HLA-G to the subpopulation of trophoblast cells which invade the uterus has generated much interest. The alternative splicing of HLA-G primary transcript, gives origin to seven isoforms, including both membrane-bound forms (HLA-G1, G2, G3, G4) and soluble forms (sHLA-G: sHLA-G5, G6, G7). sHLA-G consists predominantly of sHLA-G1 after its shedding by metalloproteinases, and secreted sHLA-G5 representing the quantitatively dominating and full-length isoforms. HLA-G expression and HLA-G genetic variations in both the mother and the embryo/fetus may be important for pregnancy outcome. It is also intuitively apparent that a gene with putative immunosuppressive and immunotolerant potential might be functional in both the mother and the embryo/fetus/placenta. Reduced or aberrant HLA-G expression seems to be associated with certain complications of pregnancy, among which preeclampsia and possibly the risk of miscarriage, and that this may be further linked to HLA-G polymorphisms. Most of the studies aimed at assessing the role of HLA-G in pregnant diseases have considered only the maternal genotype and ignored the contribution of the fetus. In this regard, the mother, placenta and the fetus form a synthesis. Therefore, studies on placental diseases should address HLA-G expression and genetic variations also to the fetus/placenta.
