Endometriosis is clinically associated with pelvic pain and infertility, with implantation failure strongly suggested as an underlying cause for the observed infertility. Eutopic endometrium of women with endometriosis provides a unique exp…

Endometriotic lesions secrete chemokines that recruit immune cells into the peritoneal cavity. The accumulation of these immune cells, especially activated macrophages and T lymphocytes, is thought to mediate inflammatory symptoms associate…

The human endometrium is a complex tissue comprised of different cell types, including epithelial, stromal, inflammatory, perivascular, and blood vessel cells. The hormonal receptivity and distribution of these cell populations change durin…

A complex network of cytokines mediates immunoregulatory responses in the pathogenesis of endometriosis. RANTES (regulated upon activation, normal T cell expressed and secreted) is a chemoattractant for monocytes and T cells. Endometriotic …

The peroxisome proliferator-activated receptors (PPARs) alpha and gamma are nuclear receptors that play important roles in inflammatory diseases like ulcerative colitis and arthritis. In this study, we examined the possible role of PPARs in…

Activated peritoneal macrophages are associated with endometriosis and may play a central role in its aetiology by releasing interleukin-1beta (IL-1beta) in response to refluxed endometrium. Pari passu with the establishment of endometrioti…

Our laboratories have focused recently on the production and localization of eotaxin, a C-C-chemokine of 8.4 kDa, whose major biological activity is the chemoattraction of eosinophils. Given evidence of autoimmune activity in the endometrio…

Several investigators have noted that hormone-dependent development of endometriosis implants lags behind that of simultaneously analysed eutopic endometrium. With the recent discovery of the oestrogen receptor-beta (ER-beta) isoform, the a…

Recent studies suggest that the symptoms associated with endometriosis are the result of local peritoneal inflammation. Increased concentrations of activated pelvic macrophages and lymphocytes and the elevated levels of specific cytokines a…

Endometriosis is a common gynecological disorder with varied symptomatology including chronic pelvic pain, dysmenorrhea, and infertility. The association of endometriosis and infertility has been recognized for years, although definite evid…

Retrograde menstruation is postulated as the initiating event in the histogenesis of endometriosis; however, subsequent steps in the pathogenesis of this common disorder remain poorly characterized. The ip accumulation of activated leukocyt…

An in vitro model developed to compare human endometrial and endometriosis stromal cells was used to examine basal and stimulated expression of interleukin (IL-6). Stromal cells isolated from normal endometrium (NE) exhibited the lowest lev…

The human endometrium undergoes a complex process of vascular and glandular proliferation, differentiation, and regeneration with each menstrual cycle in preparation for implantation. Vascular endothelial growth factor (VEGF) is an endothel…

OBJECTIVE: To investigate the presence of interleukin-8 (IL-8), a macrophage-derived angiogenic factor, in peritoneal fluid (PF) of women with and without endometriosis. DESIGN: Case-control study. SETTING: University hospital. PATIENTS:…

Endometriosis is a common gynecological disorder of unclear pathogenesis. We have established an in vitro model to investigate phenotypic similarities and differences between normal endometrial and endometriosis cells. Highly purified cultu…
