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.

Abstract

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.
