PG - 40-6 LID - 10.1016/j.jri.2010.02.004 [doi] AB - Several lines of evidence suggest that the human leukocyte antigen (HLA)-G play a key role in the regulation of human pregnancy. A sub-population of cells highly represented at the decidua belong to the myeloid-derived monocyte/macrophage lineage, which potentially interact with HLA-G expressing cells. It is proposed that HLA-G protects decidual trophoblasts from lysis by blocking the effector function of decidual monocyte/macrophages. The interaction between HLA-G and monocyte/macrophages may therefore contribute to a successful pregnancy. Here we examine existing knowledge on the convergent role of HLA-G and monocyte/macrophages in pregnancy and define the synergy that exists between these two elements in the decidua. Key features of the HLA-G gene product are discussed followed by the main characteristics of decidual monocyte/macrophages. A hypothetical model for the interaction between HLA-G and monocyte/macrophage cells at the fetal-maternal interface is proposed. CI - Copyright (c) 2010 Elsevier Ireland Ltd. All rights reserved.
