Evidence to date supports regulatory T cell (Treg) alterations in endometriosis; however, the relationship remains unclear, and Tregs have not previously been investigated with respect to infertility in endometriosis. This prospective cross…

OBJECTIVE: To study the localization of and quantify different immune cell populations in red, black, and white peritoneal endometriotic lesions and compare immune cell densities between lesions and the surrounding tissue. DESIGN: Cross-se…

STUDY QUESTION: What are the detailed endometrial tissue specific and systemic dendritic cell (DC) subset disturbances in endometriosis? SUMMARY ANSWER: This study confirms myeloid DC (mDC) and plasmacytoid DC subsets are readily identified…

In endometriosis, the lymphatic and immune systems are implicated in disease establishment and progression. The objective of this pilot study was to examine endometrial-like, and for the first time, immune cell populations in lymph nodes as…

Endometrial polyps are overgrowths of endometrial glands that typically protrude into the uterine cavity. Endometrial polyps are benign in nature and affect both reproductive age and postmenopausal women. Although endometrial polyps are rel…

Endometriosis is a gynaecological disorder characterised by the presence of endometrial-like tissue outside the uterus. It affects 10-15% of women during their reproductive age. The existence of close and complex relationship between chroni…

ObjectiveEndometrial polyps are localised growths of endometrial tissue containing glands, stroma and blood vessels, covered with epithelium. The reported prevalence of endometrial polyps is dependent upon the population being studied and t…

BACKGROUND: Dysfunctional immune response may be implicated in endometriosis pathogenesis, and dendritic cells (DC) may play greater roles in this response than previously recognized. This study set out to evaluate peripheral blood and endo…

Endometriosis is a common, benign gynecological disease affecting 10 - 15% of reproductively aged women. It is characterized by the presence of endometrial-like tissue at sites outside the uterus. The most widely accepted theory of endometr…

Recent studies suggest that changes in certain uterine immune cell populations in endometrium of women with endometriosis are likely to precede changes at ectopic sites. This preliminary study is a first look into the function of uterine-dr…

Despite the importance of neuropilins (NRPs) in a number of processes that are altered in endometriosis, such as angiogenesis and neuronal guidance, these molecules have not been previously studied in the disease. Similarly, potent lymphang…

OBJECTIVE: To investigate whether proteins secreted in urine differ between women with and without endometriosis. DESIGN: Laboratory study using human urine. SETTING: University-based laboratory. PATIENT(S): Women with and without endome…

Mounting evidence suggests that immunological responses may be altered in endometriosis. The baboon (Papio anubis) is generally considered the best model of endometriosis pathogenesis. The objective of the current study was to investigate f…

Ovarian endometriomas (n = 29) were innervated by mainly sympathetic and sensory fibers. These fibers may be involved in the generation of pain symptoms.

BACKGROUND: Endometriosis is an inflammatory condition, associated with highly dysregulated immune response at both uterine and peritoneal levels. Surprisingly, Foxp3+ regulatory T-cells, which control and suppress a range of immune respons…

ObjectiveTo explore the association between the symptom of abdominal bloating and the diagnosis of endometriosis.MethodsTwenty-six patients with endometriosis diagnosed by laparoscopy and 25 women without endometriosis were recruited to a c…

BACKGROUND: Immune alterations may be involved in the pathogenesis and progression of endometriosis. Dendritic cells (DCs) are potent antigen presenting cells that are highly involved in the initiation of the immune response. The aim of thi…

BACKGROUND: Diagnosis of endometriosis currently requires a laparoscopy and this need probably contributes to the considerable average delay in diagnosis. We have reported the presence of nerve fibres in the functional layer of endometrium …

Study objectiveTo investigate the extent and types of innervation of endometriotic lesions in various regions of the bowel.DesignRetrospective nonrandomized immunohistochemical study (Canadian Task Force classification II-3.SettingUniversit…

BACKGROUND: Endometriosis is an inflammatory condition, characterized by the presence of endometrial-like tissue outside the uterus. The immune system provides a defence mechanism in response to foreign pathogens, and macrophages play impor…

BACKGROUND: Endometriosis is a common gynaecological disease, but the pathogenesis of endometriosis and pathophysiological basis for endometriosis-associated painful symptoms are still uncertain. Little is known about neuroendocrine (NE) ce…

ObjectiveTo investigate how progestogens and combined oral contraceptives change nerve fiber density in peritoneal endometriotic lesions and to identify the types of nerve fibers still present during hormone treatment.DesignLaboratory study…

OBJECTIVE: To investigate how hormonal treatment can change nerve fiber density and to identify types of nerve fibers in endometrium and myometrium in women with endometriosis. DESIGN: Laboratory study using human tissue. SETTING: Univers…

BACKGROUND: Endometriosis is considered to be an inflammatory disease, and macrophages are the most numerous immune cells in endometriotic lesions. However, the mechanisms underlying the elevation of macrophages and their role in the pathog…

BACKGROUND: Deep infiltrating endometriosis (DIE) is a specific type of endometriosis, which can be associated with more severe pelvic pain than other forms of endometriotic lesions. However, the mechanisms by which pain is generated are no…
