Background/Objectives: Endometriosis is a prevalent gynecological illness associated with chronic pain, inflammation, and infertility, as ectopic endometrial lesions are formed. No fully effective treatment is available, and the pathogenesi…

BACKGROUND: Endometriosis is a common chronic gynaecological disorder related to the presence of ectopic foci of endometrial-like tissue, mostly in the pelvic cavity. Pathogenesis of this disease may be associated with epithelial-to-mesench…

Endometriosis is a common chronic disorder characterized by the growth of endometrium-like tissue outside the uterine cavity. The disease is associated with chronic inflammation and pelvic pain and may have an impact on the patient's fertil…

Advancements in single-cell analyzis technologies, particularly single-cell RNA sequencing (scRNA-seq) and Fluorescence-Activated Cell Sorting (FACS), have enabled the analyzis of cellular diversity by providing resolutions that were not av…

Endometriosis is a common gynecological disorder defined as the presence of endometrial-like tissue (glands and stroma) outside the uterus. The etiopathogenesis of endometriosis is still poorly recognized. It is speculated that stage-specif…

Endometriosis is a common gynecological disorder characterized by the ectopic growth of endometrial-like tissue outside the uterine cavity. Etiopathogenesis of endometriosis is poorly understood; it is plausible, however, that the disease m…

Endometriosis is a common gynecological disorder characterized by the presence of endometrial-like tissue outside the uterus. The disease is associated with disturbed local and systemic immunity. It has been reported that the proportion of …

Endometriosis is an inflammatory condition manifested by the presence of endometrial-like tissue outside of the uterine cavity. The most common clinical presentations of endometriosis are dysmenorrhea, infertility, and severe pelvic pain. F…

Endometriosis is a common gynaecological disorder characterized by the ectopic growth of endometrial tissue outside the uterine cavity. It is associated with chronic pelvic inflammation and autoimmune reactivity manifesting by autoantibody …

Endometriosis is a common gynecological disease defined by the presence of endometrial-like tissue outside the uterus, most frequently on the pelvic viscera and ovaries, which is associated with pelvic pains and infertility. It is an inflam…

Endometriosis is a disease in which endometriotic tissue occurs outside the uterus. Its pathogenesis is still unknown. The most widespread hypothesis claims that ectopic endometrium appears as a result of retrograde menstruation and its ins…

Endometriosis is defined as the presence of functional endometrial tissue outside the uterine cavity. Several hypotheses have attempted to explain the etiology and pathogenesis of endometriosis. Recently, it has been suggested that a defect…

STUDY QUESTION: Is endometriosis associated with changes in CD4⁺ CD25⁺ FOXP3⁺ regulatory T cells (Treg cells)? SUMMARY ANSWER: Endometriosis is associated with disturbed compartmentalization of CD25(high) FOXP3⁺ Treg cells. WHAT IS KNOWN …

OBJECTIVE: The present study aimed at performing proteomic analysis of matched eutopic endometrium and ovarian endometrioid cysts from women with endometriosis in order to discover any abnormal protein expression related to the disease. DES…

Endometriosis is a common gynaecological disorder manifesting by implantation and growth of endometrial tissue outside the uterine cavity. The evidence accumulates that endometriosis may be associated with abrogated regulation of energy bal…

BACKGROUND: KIR2DS5 gene encodes an activating natural killer cell receptor whose ligand is not known. It was recently reported to affect the outcome of hematopoietic stem cell transplantation. METHODOLOGY/PRINCIPAL FINDINGS: In our studie…

Endometriosis is a common gynaecological disorder due to ectopic implantation of endometrial tissue. It is manifested by pelvic inflammation and abrogation of cell-mediated immunity and may be also characterised by autoantibody production, …

Endometriosis is a common, complex and chronic disease related to ectopic implantation and growth of endometrial tissue that may manifest by pelvic pain, and accounts for over 20% of all cases of infertility in women. Endometriosis may be a…
