The endocrine system and the immune system interact closely during implantation and maintenance of pregnancy. Natural Killer (NK) cells are the leading maternal immune cells which act as a natural defense system and help in fighting infections. And a clear indictment of an industry aggressively offering fertility patients expensive ‘treatments’ and ‘therapies’ for natural killer cells.
How this immune tolerance is acquired and maintained has been a topic of intense investigation. 1. The Role of Natural Killer Cells in Human Fertility 1. I was told it was ‘perfectly normal’ for someone of my age to miscarry. Others say no and ask for the research to back it up. Jo Adetunji, The Conversation, Nick Macklon, Siobhan Quenby. NATURAL KILLER CELLS AND PREGNANCY. A women’s immune system has within it, natural killer cells and these cells have been the subject of much ongoing study to know exactly the amount of correlation the presence of natural killer cells has in the successful outcome of pregnancy and child birth through IVF.

Natural killer cells, also known as NK cells or large granular lymphocytes (LGL), are a type of cytotoxic lymphocyte critical to the innate immune system.The role of NK cells is analogous to that of cytotoxic T cells in the vertebrate adaptive immune response.NK cells provide rapid responses to virus-infected cells, acting at around 3 days after infection, and respond to tumor formation. We aimed to investigate the role of invariant natural killer T (iNKT) cells in infection-associated pregnancy loss. Natural Killer (NK) Cells are lymphocytes in the same family as T and B cells, coming from a common progenitor. ‘I’m so sorry, Ms Cave, I’m afraid we can’t detect a heartbeat.’ It was the second time in three years I’d been pregnant, and the second time the doctors had given me the devastating news I’d had a ‘silent miscarriage’. Zhou et al. Wild-type (WT) C57BL/6 mice and iN… Here, under the influence of sex steroids, there is a dramatic increase of a unique population of lymphocytes, the … Numerous decidual natural killer cells are found at the maternal-fetal interface in the placenta during early pregnancy. Natural killer T (NKT) cells are a heterogeneous group of T cells that share properties of both T cells and natural killer cells.Many of these cells recognize the non-polymorphic CD1d molecule, an antigen-presenting molecule that binds self and foreign lipids and glycolipids.They constitute only approximately 0.1% of all peripheral blood T cells.
NK cells are best known for killing virally infected cells, and detecting and controlling Natural killer (NK) cells are a sub-type of white blood cells, which are crucial in our immune system.
Natural killer cells (identified by the surface marker CD56) are the dominant type of maternal immune cell populating the uterine mucosa during formation of the placenta. Natural killer cells are a diverse group of cells that can be found in the blood and other areas of the body including the uterus. Jennifer M. Sasser. Natural Killer cell activity is now known to be a major cause of miscarriage and reduced implantation. 1 These uterine NK cells are also present in the endometrium of non-pregnant women, when they are under the control of ovarian hormones, cycling together with the glandular and stromal compartments.
