這是一個來自中國的研究論文,發表在Feb 2019生殖免疫學雜誌的臨床研究論著。
γδT cell——是一組特殊存在的T細胞,這群細胞在子宮內膜以及蛻膜中的水平跟月經周期以及稽留流產有一定的相關性。
A successful pregnancy is a complicated process that involves the precisely timed regulation of endocrine as wellas immune system.
成功懷孕是一個複雜的過程,包括內分泌和免疫系統的精確定時調節。
Despite increasing knowledge about immunology in gestation, the studies of immune cells inendometrium and decidua are still fragmented.
儘管人們對妊娠期免疫學的認識日益加深,但對子宮內膜和蛻膜中免疫細胞的研究仍然支離破碎。
Dynamic data is lacking on the transition of pre-pregnancyendometrial lymphocytes to initial pregnancy states as well as to second/third-trimester status.
關於妊娠前子宮內膜淋巴細胞向初始妊娠狀態以及向中期/中期妊娠狀態的轉變缺乏動態數據。
Here, we determined the composition of Gamma delta (γδ) T cells in endometrium and decidua from women with normalpregnancy and unexplained spontaneous abortion.
我們確定了正常妊娠和不明原因自然流產婦女子宮內膜和蛻膜中γδT細胞的組成。
We found that the frequency of γδT cells is fluctuating overthe course of pregnancy, and these changes were regulated by progesterone.
我們發現γδT細胞的水平在懷孕過程中波動,這些變化是由孕酮調節的。
Different from peripheral blood,Vδ1+ γδT cells accounted for the majority in endometrium and early-pregnancy decidua of healthy women, andendometrial stromal cells (ESCs) may involve in Vδ1/ Vδ2 shift directly.
與外周血不同,健康婦女子宮內膜和早孕蛻膜中Vδ1+γδT細胞佔多數,子宮內膜間質細胞(ESCs)可能直接參與Vδ1/Vδ2的轉移。
Moreover, an increase in the percentageof γδT cells with Vδ2 subset predominant in early-pregnancy decidua was associated with unexplained spon-taneous abortion.
此外,早期妊娠蛻膜中以Vδ2亞群為主的γδT細胞百分比的增加與不明原因的自然流產有關。
Our results unraveled the precise timing of γδT cells occurring during pregnancy and the closerelationship among endocrine, immune cells and pregnancy, which can further help understand and solve theproblem of infertility and unexplained spontaneous abortion.
我們的研究結果揭示了γδT細胞在妊娠期發生的確切時間以及內分泌、免疫細胞和妊娠之間的密切關係,有助於進一步了解和解決不孕和不明原因自然流產的問題。
γδT cell參與T細胞分化調節並影響下遊的細胞因子分泌。
在正常月經周期的分泌期,無論是否加用了孕激素,γδT 細胞在子宮內膜的水平均比增殖期升高。
其呈現如下的特點:
正常妊娠蛻膜與稽留流產的蛻膜相比,γδT cell在前者的水平低於後者。
本研究表明,γδT細胞在整個孕期都參與了母胎免疫調節,這種有序的調節是由促孕激素精確地進一步調節的。γδT細胞與孕激素原的協同作用促進了受體子宮內膜的生成,保證了移植成功。此外,早期妊娠蛻膜中γδT細胞增多,主要是Vδ2亞群增多,可能與Th1有關,而Th1可能是導致流產的重要原因。
