Regulatory T cells (Treg) expand during pregnancy and are present at the fetal-maternal interface at very early stages in pregnancy. The migration mechanisms of Treg to the pregnant uterus are still unclear. Human chorionic gonadotropin (hCG) is secreted by the blastocyst immediately after fertilization and has chemoattractant properties. Therefore, we(More)
BACKGROUND Intestinal obstruction in pregnancy is rare. Symptoms are often unspecific and a high level of suspicion is essential for early diagnosis. Fetal and maternal mortality rates are higher during pregnancy due to delay in diagnosis. CASE A 31-year-old primigravida with a history of abdominal surgery was admitted because of worsening abdominal pain,(More)
How the semi-allogeneic fetus is tolerated by the maternal immune system remains a fascinating phenomenon. Despite extensive research activity in this field, the mechanisms underlying fetal tolerance are still not well understood. However, there are growing evidences that immune-immune interactions as well as immune-endocrine interactions build up a complex(More)
PROBLEM Survivin, a tumor-promoting antiapoptotic molecule, is expressed in the human placenta. Here, we analyzed its expression during normal and pathological murine pregnancy and investigated its participation in human first trimester trophoblast cell survival and proliferation. METHOD OF STUDY We first analyzed the expression of survivin on the mRNA(More)
Reproductive immunology research has long focused on T cell responses to paternal antigens and tolerance mechanisms supporting fetal well-being. The participation of B cells herein was not widely studied. Because of the fascinating immunological uniqueness of pregnancy, it is however to be expected that such pleiotropic cells play a considerable role. In(More)
The International Consensus Conference on the treatment of primary breast cancer takes place every two years in St. Gallen, Switzerland. The panel in St. Gallen is composed of international experts from different countries. From a German perspective, it seems reasonable to interpret the voting results in the light of AGO-recommendations and S3-guidelines(More)
The key topics of this year's 14th St. Gallen Consensus Conference on the diagnosis and therapy of primary breast cancer were again questions about breast surgery and axillary surgery, radio-oncology and systemic therapy options in consideration of tumor biology, and the clinical application of multigene assays. This year, the consensus conference took(More)
Preeclampsia is a devastating pregnancy-associated disorder affecting 5% to 8% of pregnant women worldwide. It emerges as an autoimmune-driven disease, and, among others, the autoantibodies against angiotensin type 1 receptor II have been proposed to account for preeclampsia symptoms. Despite much attention focused on describing autoantibodies associated(More)
To determine the impact of adjuvant treatment with tamoxifen and aromatase inhibitors (AI) on the survival of men with breast cancer. We analyzed 257 male patients with hormone-receptor-positive breast cancer from numerous German population-based cancer registries treated with tamoxifen (N = 207) or aromatase inhibitors (N = 50). The median follow-up was(More)
PROBLEM The function of IL-10 producing regulatory B cells (Breg) during gestation is unknown. Here, we aimed to understand their participation in early pregnancy. METHOD CD19(+) CD24(hi) CD27(+) B cell frequency, measured by flow cytometry, increased with pregnancy onset but not in the case of spontaneous abortions. RESULTS B cells from non-pregnant(More)
