Existing evidence shows the importance of circulating cytokines in studying female reproductive system dysfunction. Endometriosis (EM) is thought to be associated with multiple immune cytokines, but its causality has not been proven. Utilis…

BACKGROUND: While endometriosis (EM) has been previously associated with multiple immune factors, the causal relationship underlying these associations remains unclear. OBJECTIVE: In this study, Two-sample Mendelian randomization (MR) meth…

Background: Endometriosis, a common gynecological condition, can cause symptoms such as dysmenorrhea, infertility, and abnormal bleeding, which can negatively affect a woman's quality of life. In the current study, the pathophysiological me…

Endometrial receptivity damage caused by impaired decidualization may be one of the mechanisms of infertility in endometriosis (EMs). Our previous study demonstrated that Calpain-7 (CAPN7) is abnormally overexpressed in EMs. Whether CAPN7 a…

BACKGROUND: Poor decidualization and abnormal autophagy conditions in the endometria of adenomyosis patients have been reported previously. However, the specific regulatory mechanism of decidualization in adenomyosis and its relationship wi…

Decidualization is a prerequisite for successful embryo implantation, in which elongated fibroblast-like endometrial stromal cells differentiate into more rounded decidual cells. Accumulating evidence has stressed the important role of the …

The impact of coronavirus disease 2019 (COVID-19) on endometriosis (EM) is currently unclear. Here, we aimed to describe the potential influence of COVID-19 on the pathogenesis, clinical symptoms, and treatment of EM. The cytokine storm cau…

BACKGROUND: Adenomyosis is a chronic gynecological disease characterized by invasion of the uterine endometrium into the muscle layer. In assisted reproductive technology (ART), gonadotropin-releasing hormone agonist (GnRHa) is often used t…

Abstract Background Endometrial receptivity damage caused by impaired decidualization may be one of the mechanisms of infertility in endometriosis (EMs). Our previous study demonstrated that Calpain-7 (CAPN7) is abnormally overexpressed in …

Menstruation occurs in few species and involves a cyclic process of proliferation, breakdown and regeneration under the control of ovarian hormones. Knowledge of normal endometrial physiology, as it pertains to the regulation of menstruatio…

RESEARCH QUESTION: Does adenomyosis affect IVF independent of decreased ovarian reserve, and what are the characteristics and IVF outcome of the ultra-long gonadotrophin-releasing hormone (GnRH) agonist protocol in adenomyosis? DESIGN: Obs…

Endometriosis (EMS) is the most common gynecological disease in women of reproductive age, and it is associated with chronic pelvic pain, dyspareunia and infertility. As a consequence of genetic, immune and environmental factors, endometrio…

PROBLEM: During endometriosis, there is an increase in the number of dysfunctional macrophages; however, the mechanisms underlying macrophage recruitment are not well understood. The aim of the present study was to determine the role of nat…

Endometriosis (EMS) is a female hormone‑ dependent disease with controversial reports of its etiology and pathogenesis. Apoptosis is particularly important in the human endometrium due to the dynamic cycles of proliferation and shedding. Es…

UNLABELLED: Impaired NK cell cytotoxic activity contributes to the local dysfunctional immune environment in endometriosis (EMS), which is an estrogen-dependent gynecological disease that affects the function of ectopic endometrial tissue c…

Endometriosis (EMS) is an estrogen-dependent gynecological disease with a low autophagy level of ectopic endometrial stromal cells (eESCs). Impaired NK cell cytotoxic activity is involved in the clearance obstruction of the ectopic endometr…

Endometriosis (EMS) is a common gynecologic disease that causes chronic pelvic pain, dysmenorrhea, and infertility in women. The doctrine of menstruation back flow planting and defects in the immune system are well known and widely accepted…

Abstract Endometriosis is an estrogen-dependent inflammatory disease. The anti-inflammatory cytokine IL-10 is also increased in endometriosis. IL-10 production by Th17 cells is critical for limiting autoimmunity and inflammatory responses. …

It was previously demonstrated that anomalous expression of indoleamine 2,3-dioxygenase-1 (IDO1) in endometrial stromal cells (ESCs) stimulated an inflammatory response that subsequently initiated the activation of immunosuppressive macroph…

Abstract The dysfunction of NK cells in women with endometriosis (EMS) contributes to the immune escape of menstrual endometrial fragments refluxed into the peritoneal cavity. The reciprocal communications between endometrial stromal cells …

Abstract Foxp3 + regulatory T (T reg ) cells contribute to the local dysfunctional immune environment in endometriosis, an estrogen-dependent gynecological disease, which affects the function of ectopic endometrial tissue clearance by the i…

The chemokine stromal cell-derived factor-1 (C-X-C motif chemokine ligand 12; CXCL12) is important in the recruitment of leukocytes to the peritoneal cavity and the regulation of endometriotic tissue growth in endometriosis patients. Howeve…
