PROBLEM: Chronic inflammation is important for the occurrence of endometriosis, but the molecular mechanisms are still poorly understood. TLR4 is not only expressed on immune cells but is also present in the human endometrium, and its regul…
PROBLEM: Uterine natural killer cells (uNK) have been thought to play a key role in endometriosis and infertility. We investigated the expression of CD56, CD16, and NKp46 in endometrial tissues from 61 women with unexplained recurrent pregn…
PROBLEM: Estradiol can directly affect epithelial cells or indirectly affect epithelial cells via stromal fibroblast secretion of growth factors, such as keratinocyte growth factor (KGF). The purpose of the present study was to determine wh…
PROBLEM: To investigate the relationship between the expression of natural cytotoxicity receptors (NCRs) on peritoneal fluid (PF) natural killer (NK) (pfNK) cells and cytokine production by pfNK cells in women with endometriosis. METHOD OF…
PROBLEM: Immune tolerance to endometriotic cells is important to promote endometriosis. Tryptophan 2,3-dioxygenase (TDO) enhances immune tolerance by catabolizing tryptophan to kynurenine. We studied whether interleukin-1β (IL-1β), a typica…
Implantation and the establishment of pregnancy in mammals involves an intricate interplay of hormones, cytokines, growth factors, proteins, lipids, ions and the extracellular matrix between the uterine epithelium, stroma, immune cells and …
Advancement in the field of ART has lead to the possibility of achieving good quality embryos. However, the success rate in ART needs further improvement. This is largely dependent on identifying the receptive endometrium for the successful…
The immune system in the female reproductive tract (FRT) does not mount an attack against human immunodeficiency virus (HIV) or other sexually transmitted infections (STI) with a single endogenously produced microbicide or with a single arm…
PROBLEM: Endometriosis is recognized as a chronic inflammatory disease and is related to immune response. There have been reports that revealed the different distribution of macrophage within the eutopic endometrium of women with endometrio…
PROBLEM: The anti-inflammatory impact of three polyunsaturated fatty acids (3-PUFA) in endometriosis is incompletely understood. The effect of 3-PUFA on endometriosis-like lesions is evaluated as a potential anti-inflammatory treatment targ…
PROBLEM: How is the tumor necrosis factor (TNF) α-induced inhibitor of apoptosis (IAP) protein expression in endometriotic stromal cells (ESCs) involved in cell viability and signaling pathways? METHOD OF STUDY: Endometriotic stromal cells…
PROBLEM: Chronic endometritis (CE) is a poorly investigated and probably underestimated pathology, which may cause abnormal uterine bleeding (AUB), pain, and reproductive failures. Due to undefined symptoms and the normal presence of leukoc…
PROBLEM: Endometriosis affects 5-10% of women and is characterized by the growth of endometrial tissue outside of the uterus. Establishing new blood supply is a fundamental requirement for endometriosis lesion growth. Endothelial progenitor…
PROBLEM: Uterine leiomyomata are the most common reproductive tumor in women, and their cause is not known. METHODS OF STUDY: Plasma samples from 155 women (74 with and 81 without ultrasound-confirmed leiomyoma) from a new study of leiomyo…
PROBLEM: The purpose of this study is to evaluate the involvement of death receptor (DR) 6 in the pathogenesis of endometriosis. METHODS OF STUDY: Endometriotic cyst stromal cells (ECSCs) and normal endometrial stromal cells (NESCs) were i…
PROBLEM: We evaluated whether the expression of NF-кB p65 subunit is increased in the eutopic endometrium and/or in the ovarian endometrioma of women with advanced stage endometriosis, and ascertained in vitro effects of proinflammatory cyt…
PROBLEM: To search for molecular markers of endometriosis the following polymorphisms: p53 codon 72 Pro (apoptosis), TNF alpha-308 (inflammation), VEGF-1164AA (angiogenesis), and SOD2 (oxidative stress) were investigated. METHOD OF STUDY: …
PROBLEM: To characterize the genetic variation across the MMP-2 and TIMP-2 gene with the risk of advanced-stage endometriosis. METHOD OF STUDY: Ten single-nucleotide polymorphisms (SNPs) and haplotype associations between MMP-2 (9082A>G, 9…
PROBLEM: To evaluate CD4(+) CD25(high) Foxp3(+) cells and IL-6, IL-10, IL-17, and TGF-β in the peritoneal fluid of women with endometriosis. METHOD OF STUDY: A total of ninety-eight patients were studied: endometriosis (n = 70) and control…
PROBLEM: We investigated the association of COX -2 gene-765G/C polymorphism and risk of advanced-stage endometriosis in Korean women. METHOD OF STUDY: This study consisted of 268 women with advanced-stage endometriosis and 242 control wome…
PROBLEM: To assess whether interleukin (IL)-1beta, IL-18 and interleukin-1 converting enzyme (ICE) are involved in the pathogenesis of endometriosis. METHOD OF STUDY: Peritoneal fluid (PF) was obtained from 85 women with and without endome…
PROBLEM: To evaluate the effects of the anti-inflammatory and anti-angiogenic roles of LXA4 on endometriosis in mice. METHOD OF STUDY: Endometriosis was induced in 40 mice and separated into two groups. LXA4 group was administered by LXA4 …
PROBLEM: Hepatocyte Growth Factor (HGF) secretion facilitates epithelial cell growth and development in the female reproductive tract (FRT) and may contribute to pathological conditions such as cancer and endometriosis. We hypothesized that…
PROBLEM: To establish a multilocus model for studying the effect of dioxin receptor complex components and detoxification-related enzymes on advanced endometriosis. METHOD OF STUDY: Six single-nucleotide polymorphisms (SNPs) and two deleti…
PROBLEM: Toll-like receptors (TLRs) are innate immune receptors that mediate the pattern recognition of, and response toward, pathogens and host-derived danger signals. We reported that cyclooxygenase-2 (COX-2) and microsomal prostaglandin …
