Abstract
Adequate endometrial stromal cell (ESC) decidualization is vital for endometrial health. Given the importance of extracellular vesicles (EVs) in intercellular communication, we investigated how their protein landscape is reprogrammed and dysregulated during decidual response. Small EVs (sEVs) from human ESC-conditioned media at Day-2 and -14 following decidual stimuli were grouped as well- (WD) or poorly decidualized (PD) based on their prolactin secretion and subjected to mass spectrometry-based quantitative proteomics. On Day 2, in PD- versus WD-ESC-sEVs, 17 sEV- proteins were down-regulated (C5, C6; complement/coagulation cascades, and SERPING1, HRG; platelet degranulation and fibrinolysis) and 39 up-regulated (FLNA, COL1A1; focal adhesion, ENO1, PKM; glycolysis/gluconeogenesis, and RAP1B, MSN; leukocyte transendothelial migration). On Day 14, in PD- versus WD-ESC-sEVs, FLNA was down-regulated while 21 proteins were up-regulated involved in complement/coagulation cascades (C3, C6), platelet degranulation (SERPINA4, ITIH4), B-cell receptor signalling and innate immune response (immunoglobulins). Changes from Days 2 to 14 suggested a subsequent response in PD-ESC-sEVs with 89 differentially expressed proteins mostly involved in complement and coagulation cascades (C3, C6, C5), but no change in WD-ESC-sEVs ESC. Poor decidualization was also associated with loss of crucial sEV-proteins for cell adhesion and invasion (ITGA5, PFN1), glycolysis (ALDOA, PGK1) and cytoskeletal reorganization (VCL, RAC1). Overall, this study indicates varied ESC response even prior to decidualization and provides insight into sEVs-proteomes as a benchmark of well-decidualized ESC. It shows distinct variation in sEV-protein composition depending on the ESC decidual response that is critical for embryo implantation, enabling and limiting trophoblast invasion during placentation and sensing a healthy embryo.

Abstract
Studies of T cell-mediated immunity in the human female genital tract have been problematic due to difficulties associated with the collection of mucosal samples. Consequently, most studies rely on biopsies from the lower female genital tract or remnant tissue from hysterectomies. Availability of samples from healthy women is limited, as most studies are carried out in women with underlying pathologies. Menstruation is the cyclical sloughing off of endometrial tissue, and thus it should be a source of endometrial cells without the need for a biopsy. We isolated and phenotyped T cells from menstrual and peripheral blood and from endometrial biopsy-derived tissue from healthy women to determine the types of T cells present in this compartment. Our data demonstrated that T cells isolated from menstrual blood are a heterogeneous population of cells with markers reminiscent of blood and mucosal cells as well as unique phenotypes not represented in either compartment. T cells isolated from menstrual blood expressed increased levels of HLA-DR, αEβ7 and CXCR4 and reduced levels of CD62L relative to peripheral blood. Menstrual blood CD4+ T cells were enriched for cells expressing both CCR7 and CD45RA, markers identifying naïve T cells and were functional as determined by antigen-specific intracellular cytokine production assays. These data may open new avenues of investigation for cell mediated immune studies involving the female reproductive tract without the need for biopsies.

Abstract
PROBLEM Cytokines are obviously very important in an established pregnancy, but what about human embryo implantation? METHODS Literature review. RESULTS We first discuss the necessity and limits of animal models, and then review the few cytokines which have been demonstrated by knock-out methods to be absolutely necessary for embryo implantation using in animal models. We then review what is known or discussed about the role of other cytokines as deduced from quantitative and/or qualitative dysregulation in animals and in humans. CONCLUSIONS Cytokines are indeed involved in implantation as they are in ongoing pregnancy and delivery. Relevance to infertility and recurrent pregnancy loss is discussed.

Abstract
In a brief introduction, this review states why the presence of immune cells at the interface poses problems for an immunologist (Medawar paradigm). Different types of placentation are then discussed, and the various interactions with leukocytes, the extreme being with the equids where a certain degree of 'attack' is often seen. The limits of animal models when dealing with the human situation are emphasized. It is then stated why the various phases of pregnancy are different, and an analysis made of the cellular movements at the implantation, peri-implantation, immediate post-implantation and resorption windows in rodents. Details of the cellular components involved are given, as are hints for the human situation. The Th1/Th2 paradigm is described, with clinical examples, and its limits. Thus, the newly appraised dual role of natural killer (NK) cells is discussed, with examples in rodents and in humans (pre-eclampsia, implantation failure, abortion systems). Clinical data on the IL-12/IL-18/NK tripod and implantation failure in humans are detailed.

Abstract
An aberrant interaction at the maternal/fetal interface between the genetically distinct fetal trophoblast cells and cells of the maternal decidua has been proposed as an initiating factor in one of the major complications of human pregnancy, preeclampsia. Biochemical and epidemiological studies suggest that the immune system plays an important role in preeclampsia. Thus, the aim of this study was to determine the decidual gene expression status in preeclampsia of one of the key components of the adaptive immune system. Total RNA was extracted from decidua collected from women with normal pregnancies and those complicated by preeclampsia. Reverse Northern analysis was performed on 72 cDNAs from human decidua and differentially expressed genes identified were analysed further using semi-quantitative RT-PCR and Northern blot analysis. Expression of the gene encoding the constant region of the heavy chain of immunoglobulin G (IgG CRHC) was shown to be down-regulated in association with preeclampsia. These data support the hypothesis that immune maladaptation may play an important role in the pathogenesis of preeclampsia.

Abstract
Placental bed biopsies were examined in three groups of pregnant women for maternal vascular response to placentation as well as for the presence of cells associated with local immunosuppression activity. In the group of women undergoing legal abortion, the histological appearance of trophoblastic invasion was normal in all but one, and the proportion of immunosuppressor cells was also normal. In the missed miscarriage group the histological appearances were abnormal except in one patient. In women with a history of recurrent miscarriage who had miscarried after immunization, placentation was normal in some and defective in others. Immunosuppressor cells appeared to be diminished in number, although there was no correlation between the cytotoxic status of their sera and their pregnancy outcome.

Abstract
Stromal leucocytes in normal premenopausal human endometrium were characterised by an indirect immunoperoxidase technique employing a panel of monoclonal antibodies. T cells were scanty in proliferative endometrium but increased in frequency in the secretory phase of the menstrual cycle. An additional population of phenotypically unusual lymphocytes (CD2-positive, CD3-negative) was detected in the stratum functionalis in mid- and late secretory phase endometrium, particularly in areas exhibiting pseudodecidual change. The distribution of these unusual lymphocytes mirrored that of the so-called "endometrial stromal granulocytes," which have recently been shown to be granulated lymphocytes. Macrophages were common throughout the menstrual cycle. B lymphocytes were detected in lymphoid aggregates in the basalis but rarely in the functionalis.

Abstract
Immunohistochemical techniques have been used to investigate the expression of fetal trophoblast antigens and the maternal leucocytic response in molar pregnancy and choriocarcinoma. The antigenic phenotype of morphologically defined trophoblast populations in complete, partial and invasive moles was analogous to that in normal pregnancy. All trophoblast phenotypes described in normal pregnancy were also identified in choriocarcinoma, suggesting that extensive differentiation into heterogeneous subgroups occurs in malignant trophoblast. The maternal leucocytic infiltrate in molar pregnancy consisted of T lymphocytes and class II MHC-positive macrophages. CD2-positive, CD3-negative lymphocytes were identified in molar decidua but not in uterine tissue in choriocarcinoma. Similarly, endometrial granulocytes were present in molar decidua but not in choriocarcinoma; these cells were associated with decidualization rather than with fetal trophoblast.
