Natural killer (NK) cells are recruited into the uterine stroma during establishment of the hemochorial placenta and are proposed regulators of uterine spiral artery remodeling. Failures in uterine spiral artery remodeling are linked to diseases of pregnancy. This prompted an investigation of the involvement of NK cells in placentation. NK cell depletion decreased the delivery of proangiogenic ...
Implantation: can immunological parameters of implantation failure be of interest for pre-eclampsia?
We restate briefly why we consider that the Th1/Th2 paradigm, as useful as it has been, is now no longer adequate and is obsolete. We take as an example the role of IL-18, abortifacient at high doses but cardinal for the control of natural killer (NK) cell effects on spiral artery remodelling in mice, and likely also in humans. We then describe briefly our recent studies on cytokine defects and...
Uterine natural killer (uNK) cells remarkably increase in number after implantation. NK cells or their precursors migrate from the blood stream and contribute to the increase. However, the contribution of uNK cells present in the virgin uterus has been unclear. To elucidate this issue, we examined uterine leukocyte subsets during pregnancy in BALB/c mice. The most dramatic change was the massiv...
Expression of the oestrogen and progesterone receptors on uterine mucosal leukocytes has been examined by dual immunohistology. Neither the oestrogen receptor nor the progesterone receptor was expressed by lymphocytes, macrophages or the distinctive population of uterine natural killer (NK) cells. Although the accumulation and survival of these NK cells appears to be hormonally dependent, the e...
