PG - 342-5 LID - S0198-8859(16)00028-8 [pii] LID - 10.1016/j.humimm.2016.01.019 [doi] AB - Pregnancy is associated with increased levels of soluble (s) human leukocyte antigen (HLA)-G molecules, while during abortion these molecules are decreased. To date, little is known about the role of sHLA-G isoforms during abortion. In this study, we investigated the levels of total sHLA-G and its isoforms: HLA-G1 (membrane shedded isoform) and alternative spliced HLA-G5 in plasma samples obtained from 55 women who had experienced spontaneous abortion, 108 pregnant healthy women and 56 non pregnant healthy women. We found that pregnant women exhibited higher amounts of sHLA-G compared to either non pregnant women or women with abortion. Among women who had experienced spontaneous abortion, women with recurrent abortions (RSA) had lower sHLA-G than women with only one abortion. In particular, RSA women were characterized by the absence of sHLA-G1 isoform, suggesting a possible implication in abortion event.
