Background. Endometriosis (EMs) is a non-malignant gynecological disease, whose pathogenesis remains to be clarified. Recent studies have found that hypoxia induces epithelial-mesenchymal transition (EMT) as well as epigenetic modification …

Defined by the presence of endometrial-like cells outside the uterus, endometriosis is one of the most diagnosed gynecological disorders, affecting 5 to 10 % of reproductive age women, but the true incidence is unknown. Endometriosis is a m…

Abstract The establishment and progression of ectopic endometrial implants are dependent upon their interaction with and responsiveness to the stimuli present in their new environment. According to our and other previous studies, immune cel…

Our previous studies showed a marked deficiency in interleukin 1 receptor type II (IL1R2) in the endometrial tissue of women with endometriosis, particularly in epithelial cells. We believe that such a deficiency in IL1R2, a potent and spec…

BACKGROUND: Endometriosis is a disease where endometrial tissue implants in ectopic locations. Remodelling of the extracellular matrix (ECM) is a prerequisite for the implantation of this tissue to be possible. METHODS: In this study, we de…

Numerous functional changes were observed in the intrauterine endometrial tissue of women with endometriosis. Our previous studies revealed a marked decrease in the expression of interleukin-1 receptor type 2 (IL-1RII), a decoy receptor kno…

Endometriosis, the ectopic development of endometrial tissue, is, particularly in peritoneal endometriosis, believed to result from tubal reflux of menstrual tissue. The release of cytokines and growth factors by refluxed endometrial cells …

BACKGROUND: For the implantation of endometrium in ectopic locations, remodelling of the extracellular matrix (ECM) is necessary. Many studies have shown an increased expression of various proteases in the ectopic endometrium of women with …

Interleukin 1 (IL-1) is a major proinflammatory cytokine that is believed to play a central role in the pathophysiology of endometriosis. The IL-1 receptor type II (IL-1RII) is known to bind to IL-1 and to inhibit its biological effects. In…

PROBLEM: Endometriosis is associated with a chronic inflammatory process, and the increased number of activated peritoneal macrophages is one of the major hallmarks of this process. The medical treatment of the disease, which is based on th…

PROBLEM: Monocyte chemotactic protein-1 (MCP-1), a potent inducer of macrophage recruitment and activation, is overexpressed in the eutopic endometrium of women with endometriosis. Eutopic endometrial cells of women with endometriosis secre…

Endometriosis, an oestrogen-dependent disorder affecting women of reproductive age, is associated with active angiogenesis and an increased recruitment of leukocyte into the peritoneal cavity where the implants often develop. The role of oe…

Endometriosis, one of the most frequently occurring gynecological disorders, is estrogen dependent and is often associated with immunological changes. These include increased macrophage activation and infiltration into the endometriotic imp…

The growth of endometrial cells in ectopic locations (endometriosis) is dependent on the establishment of an adequate blood supply. Neovascularization (angiogenesis) is therefore a vital step toward the progression of this disease. We first…

Endometriosis, a frequent oestrogen-dependent disease believed to result from an aberrant proliferation of endometrial tissue outside the uterine cavity, is associated with an increased expression of monocyte chemotactic protein-1 (MCP-1) i…

OBJECTIVE: To estimate the concentration and the biologic activity of monocyte chemotactic protein-1 (MCP-1) in the peritoneal fluid (PF) of women with and without endometriosis. DESIGN: A case control study was conducted. SETTING: Gyneco…

Endometriosis is generally associated with an immunoinflammatory process that takes place in the peritoneal cavity of patients. Interleukin (IL)-6, a multifunctional cytokine involved in numerous immunological and proliferative processes, h…
