Granulated lymphocytes with an unusual antigenic phenotype (CD56+ CD38+ CD2 +/- CD3- CD16-) form a substantial proportion of leukocytes in human endometrial stroma. The purpose of this study was to examine morphological and antigenic heterogeneity in endometrial granulated lymphocytes (eGL) in imprint preparations, paraffin-embedded sections and frozen(More)
BACKGROUND In areas of endemic transmission, malaria in pregnancy is associated with severe maternal anaemia and low-birthweight babies. We studied the efficacy of intermittent treatment doses of sulphadoxine-pyrimethamine in preventing malaria and severe anaemia in pregnancy in a double-blind placebo-controlled trial among primigravid women living in(More)
The most abundant immune cells in the uterine decidua around the time of implantation and early placental development are the uterine natural killer (uNK) cells. Altered numbers of uNK cells have been associated with several human reproductive disorders, including recurrent miscarriage, recurrent implantation failure, uterine fibroids, sporadic miscarriage,(More)
Leukocytes comprise approximately 30-40% of decidual stromal cells in early human pregnancy. The major leukocyte component is the uterine natural killer (uNK) cells. Despite over 20 years of research the functional role of these cells in situ remains unknown although they have been proposed to play roles in immunotolerance, regulation of trophoblast(More)
INTRODUCTION Young infants are protected from measles infection by maternal measles antibodies. The level of these antibodies at birth depends on the level of antibodies in the mother and the extent of placental transfer. We investigated predictors of levels of measles antibodies in newborns in rural Kenya. METHODS A total of 747 paired maternal-cord(More)
Thyroid hormones (THs) are essential for normal fetal development, with even mild perturbation in maternal thyroid status in early pregnancy being associated with neurodevelopmental delay in children. Transplacental transfer of maternal THs is critical, with increasing evidence suggesting a role for 3,3',5-tri-iodothyronine (T3) in development and function(More)
Antigen expression by villous and extravillous human trophoblast populations at discrete anatomical sites has been reviewed. The various different antigenic phenotypes have been highlighted using a panel of monoclonal antibodies reactive with characteristic trophoblast membrane antigens, a trophoblast-leucocyte common antigen, class I MHC antigens,(More)
The active form of vitamin D, 1,25-dihydroxyvitamin D(3) (1,25[OH](2)D(3)) is a potent immunomodulatory seco-steroid. We have demonstrated that several components of vitamin D metabolism and signaling are strongly expressed in human uterine decidua from first trimester pregnancies, suggesting that locally produced 1,25(OH)(2)D(3) may exert immunosuppressive(More)
Remodeling of uterine spiral arteries is critical for the continuation of a successful pregnancy. Uterine natural killer (uNK) cells are the predominant leukocyte population in the early pregnant decidua, and a role for these cells in spiral artery remodeling in pregnancy has been suggested. Angiogenic growth factors were measured in isolated uNK and total(More)
Apoptosis has been implicated in the pathogenesis of several diseases and is partly regulated by bcl-2, which blocks the apoptotic pathway and promotes cell survival. Apoptosis and bcl-2 expression were examined in paired eutopic and ectopic endometrium from women with endometriosis (n = 30 samples) or adenomyosis (n = 15 samples) and compared with control(More)
