ABSTRACT
AIM:
To investigate the expression of NKG2A,NKG2D and their ligands in pregnancy uterine micro-environment and to probe the function of NKG2A and NKG2D imbalance expression during the immunotolerance at the fetal-maternal boundary.METHODS:
Decidual lymphocytes and peripheral lymphocytes were obtained from 30 women during 6-9 weeks of pregnancy who were undergoing selective termination.FACS technology was used to detect NK cells number and NKG2A,NKG2D expression.RT-PCR was used to investigate HLA-E and MICA mRNA in trophoblast tissue.RESULTS:
Natural killer cells predominate,accounting for 70% of pregnancy endometrial lymphocytes.FACS results indicated that NKG2A was significantly increased in decidual NK cells as compared with that in peripheral NK cells,accounting for 97.86%?1.75% and 33.35%?10.92%.The difference between them in NKG2A expression was significant(P
