The State of Peripheral Blood Natural Killer Cells and Cytotoxicity in Women with Recurrent Pregnancy Loss and Unexplained Infertility
Objective : The prognostic value of peripheral natural killer (pNK) cells, as a screening test in women with recurrent pregnancy loss (RPL) and unexplained infertility is still a matter for discussion. The aim of this study was to compare the percentage of circulating CD56+NK cells, CD69 and perforin markers between women with unexplained infertility and RPL with healthy control group. Material...
متن کاملUterine natural killer cells and angiogenesis in recurrent reproductive failure.
BACKGROUND Increased numbers of phenotypically unusual CD56(bright) CD16- uterine natural killer (uNK) cells have been associated with recurrent reproductive failure. uNK cells produce angiogenic growth factors and are potential regulators of decidual angiogenesis in early pregnancy. The final common mechanism for early pregnancy loss is thought to be early onset of the maternal circulation and...
متن کاملDisturbed endometrial NF-κB expression in women with recurrent implantation failure.
OBJECTIVE This study was planned to investigate whether expression levels of endometrial NF-κB1 and NFκB p65 changes in women with recurrent implantation failure (RIF). PATIENTS AND METHODS The study group consists of 30 RIF patients having at least three previous failed IVF cycles. The control group comprises of 30 patients having one or no previous failed attempt. Endometrial samples were o...
متن کاملI-24: Recurrent Implantation Failure
Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...
متن کاملCD16- CD56+ natural killer cells after bone marrow transplantation.
Natural killer (NK) cells are phenotypically defined as lymphocytes expressing the antigens CD56 and mostly CD16 (Fc gamma RIII), but lacking CD3. A small CD3- CD16- CD56+ NK cell subset has been described in normal individuals representing less than 2% of peripheral blood lymphocytes. We analyzed here 70 patients for their reconstitution of the immune system during follow-up after autologous o...
