ABSTRACT
Precise mechanism which the fetus can escape from mother's immune rejection is not well understood yet during last 50 years. The clarification of immune mechanism at the feto-maternal interface is very important, because this can be a common pathogenesis of various pathologic conditions including spontaneous abortion and habitual abortion. The pivot of this mechanism is cross-talk between the expression of HLA-C, E, G on the extravillous cytotrophoblasts and their receptors on decidual NK (natural killer) cell. The mechanism through which HLA-C, E, G regulation on the extravillous trophoblast is poorly understood. The IFN-gamma is known to be harmful to the successful maintenance of early pregnancy. OBJECTIVE:
To clarify whether the IFN-gamma could be involved in the regulation of the HTR-8/SVneo human first trimester cell line.METHODS:
We investigated the effects of IFN-gamma only or with other cytokines on the HLA-C, E, G transcripts in human first trimester trophoblast cell-line by using Reverse Transcription Polymerase Chain Reaction (RT-PCR).RESULTS:
The trophoblast cells expressed HLA-C, E constitutively. When cultured in the presence of IFN-gamma only or with other cytokines, HLA-C, E transcripts were not significantly affected.CONCLUSION:
These results suggest that harmful IFN-gamma to maintain early pregnancy may affect through another mechanism besides regulation of HLA-C, E on the extravillous cytotrophoblasts at the feto-maternal interface.
