To test whether GnRH agonist could alter in vivo human immune cells and whether the alteration is related to the success of pregnancy in an in vitro fertilization-embryo transfer (IVF-ET) program.
Thirty-six infertile patients were enrolled under the long protocol of GnRH agonist (buserelin acetate) and superovulation with gonadotropin from our IVF-ET program. Peripheral B cells, NK cells, CD4+ and CD8+ T cells, and the expression of CD69, CD25, HLA-DR, and CD71 antigens on the T cells were serially examined by dual-color flow cytometry.
B cells, NK cells, CD8+ T cells, and CD71+ T lymphocyte subpopulations were not changed throughout the whole course of treatment. CD4+ T cell and CD25+ T cell subpopulations were significantly down-regulated when the GnRH agonist was used for approximately 2 wk. CD3+CD69+, CD3+CD25+, and CD3+DR+ lymphocyte subpopulations were increased at 7 days (during implantation) and at 14 days after embryo transfer in pregnant patients, but not in patients who failed to get pregnant.
The GnRH agonist had a transiently immunosuppressive effect on CD4+ and CD25+ T cells, but CD69+, CD25+, and HLA-DR+ T cells were activated during and after successful implantation.
检测促性腺激素释放激素(GnRH)激动剂是否能改变体内人类免疫细胞,以及这种改变是否与体外受精-胚胎移植(IVF-ET)项目中的妊娠成功相关。
从我们的IVF-ET项目中选取36例采用GnRH激动剂(醋酸布舍瑞林)长方案并使用促性腺激素进行超排卵的不孕患者。通过双色流式细胞术连续检测外周血B细胞、自然杀伤(NK)细胞、CD4⁺和CD8⁺ T细胞,以及T细胞上CD69、CD25、人类白细胞抗原-DR(HLA-DR)和CD71抗原的表达。
在整个治疗过程中,B细胞、NK细胞、CD8⁺ T细胞和CD71⁺ T淋巴细胞亚群未发生变化。当使用GnRH激动剂约2周时,CD4⁺ T细胞和CD25⁺ T细胞亚群显著下调。在胚胎移植后7天(着床期)和14天时,妊娠患者的CD3⁺CD69⁺、CD3⁺CD25⁺和CD3⁺DR⁺淋巴细胞亚群增加,而未妊娠患者则未增加。
GnRH激动剂对CD4⁺和CD25⁺ T细胞有短暂的免疫抑制作用,但在成功着床期间及之后,CD69⁺、CD25⁺和HLA-DR⁺ T细胞被激活。
