PG - 3056-60 LID - 10.3109/14767058.2015.1114085 [doi] AB - OBJECTIVE: To determine role of human leukocyte antigen (HLA)-G, CD8, CD16, CD56, interferon (IFN)-gamma, and tumor necrosis factor (TNF)-alpha for recurrent miscarriages in feto-maternal interface. METHOD: Chorion and decidua samples were obtained from 11 women with unwanted pregnancies (healthy pregnancy, HP) and 10 women with missed abortion diagnosis after at least two pregnancy losses (recurrent miscarriage, RM). In addition, endometrial tissues were obtained from 10 non-pregnant women (NonP). The expressions of markers were evaluated using the Western blot analysis. The values obtained between different groups were compared. RESULTS: The highest protein expression of CD56 was found in the HP compared to NonP and RM. Meanwhile, the lowest protein expression of CD16 was observed in the NonP compared to HP and RM. The HLA-G expression exhibited the highest level in HP; however, there was no statistically significant difference between groups. CD8 and IFNgamma expressions were lowest in the NonP group; however, TNF-alpha was highest in the RM group. CONCLUSIONS: The CD56 expression of uterine NK cells may be an indicator of a HP. However, not statistically significant, the increased expression of CD16, CD8, and also significantly increased expression of TNF may be associated with the predominant cytotoxic activity in the maternal immune system in patients with RM. Although there was no change in the expression of HLA-G, this finding may mean that the maternal immune system is unresponsive to HLA-G-mediated immunosuppressive signals originating from the fetus in these cases.
