Variation in natural killer activity in peripheral blood during the menstrual cycle.

P-162: Pathophysiology of Endometriosis is Interacted by MIF, its Receptor and COX-2

Background: Endometriosis is a gynecological disease associated with severe pelvic pain and infertility. Immunological changes that occur in patients with endometriosis include reduced natural killer cell and T-lymphocyte cytotoxicity in the peritoneal fluid, and an elevated number of activated macrophages. MIF via its receptor, CD74, initiates a signaling cascade that leads to proliferation an...

Variations in T-helper 17 and Regulatory T Cells during The Menstrual Cycle in Peripheral Blood of Women with Recurrent Spontaneous Abortion

افزایش سلول هایNK خون محیطی و ارتباط آن با سقط مکرر

Introduction & Objective: Undoubtedly reproduction as a means of human survival and recurrent spontaneous abortion being the most prevalent complication of pregnancy with a three percent outbreak and an influential problem on human life have always been the subject of interest among researchers. Different factors are involved in recurrent spontaneous abortion among which immunological disord...

P-142: Adenosine Deaminase Activity during Menses, Follicular and Luteal Phases of Menstrual Cycle

Background: In recent years, numerous regulators of gonadal function have been studied. Adenosine deaminase(ADA) is widely distributed throughout human tissues and may contribute in the regulation of menstrual cycle. The purpose of this study was to determine the plasma activities of total adenosine deaminase (ADAT), and its isoenzymes, ADA1 and ADA2, and ADA1/ADA2 ratio during the menses, foll...

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...
