Human Decidual Lymphocytes and their Placental Ligands

超出提供的空间。本研究的具体目的是检测人蜕膜淋巴细胞的受体、配体和功能，以期了解它们在着床和妊娠中的可能作用。尤其是，我们希望。目的：研究人类蜕膜自然杀伤(NK)细胞过度表达的可能参与免疫反应下调的新蛋白的生物化学和可能的功能，继续分析这些细胞的转录谱，并研究其细胞毒性和分泌细胞因子的能力。。通过研究不变NKT(INKT)细胞与多种细胞上表达的CDLD的相互作用，通过检测它们的V_谱系与细胞因子分泌的关系，通过检验它们在母胎界面调节免疫反应的假说，通过检查它们的完整转录谱，来评估不变NKT细胞在蜕膜中的作用。。检测蜕膜NK细胞和iNKT细胞的I类MHC蛋白配体及GM-CSF受体在胎盘中的表达，以及胎盘绒毛外细胞滋养细胞与NK、iNKT细胞及GM-CSF的相互作用。=ERFORMANCE SITE(S)(组织、城市、州)哈佛大学、剑桥、马萨诸塞州关键人员========================================Section End===========================================

EXCEED THE SPACE PROVIDED. The specific aims of this research are to examine the receptors, ligands, and functions of human decidual lymphocytes with a view to understanding their possible roles in implantation and pregnancy. In particular, we wish." . To examine the biochemistry and possible functions of novel proteins overexpressed by human decidual natural killer (NK) cells that may be involved in down-modulation of the immune response, to continue analysis of the transcriptional profiles of these cells and to study their cytoxicity and ability to secrete cytokines. . To assess the role of invariant NKT (iNKT) cells in the decidua by studying their interaction with CDld expressed on several cell types, by examining the relation of their V_ repertoire to cytokine secretion, by testing the hypothesis that they function to regulate the immune response at the maternal-fetal interface and by examining their complete transcriptional profiles. . To examine the expression in the placenta of putative Class I MHC protein ligands for decidual NK and iNKT cells and of the GM-CSF receptor and to examine the interaction of placental extravillous cytotrophoblasts with NK and iNKT cells and with GM-CSF. =ERFORMANCE SITE(S) (organization, city, state) Harvard University, Cambridge, MA KEY PERSONNEL ========================================Section End===========================================
