Ihre Entstehung ist noch teilweise ungeklärt.\nStand der Forschung\nFest steht, dass uterine Dysperistalsis eine verstärkte retrograde Menstruation nach sich zieht, was für Oberflächenschädigung am Peritoneum prädisponiert und so wohl die Implantation disseminierter endometrialer Zellen erleichtert wird. Das eutope Endometrium von Frauen mit Endometriose zeigt viele Veränderungen im Vergleich zu Kontrollen, die ektopen endometrialen Zellen der Endometrioseläsionen selbst haben ein verändertes Potenzial für Adhäsion, Invasion und Proliferation. Neben der Fähigkeit zur lokalen Östrogensynthese und relativen Progesteronresistenz weisen rezente Studien auf die Bedeutung epigenetischer Veränderungen hin. Durch die immunologische Dysfunktion bei Endometriose besteht einerseits eine verminderte lokale Immunreaktion mit reduzierter peritonealer Clearance, welche die Implantation von endometrialen Zellen nach retrograder Menstruation erleichtert, andererseits unterstützt ein proinflammatorisches Mikromilieu die Etablierung von Endometrioseläsionen; beide Mechanismen sind für die Ätiologie und Pathogenese zentral.\nAusblick\nRezente Studien deuten zunehmend auf eine Beteiligung von endometrialen Stammzellen hin. Aufgrund ihres hohen proliferativen Potenzials, erweiterter Differenzierungsmöglichkeiten und der enormen Regenerationsfähigkeit begünstigen endometriale Stammzellen die Entstehung von Endometriose.\nAbstract\nBackground\nEndometriosis is one of the most common benign diseases in the field of gynecology; however, after years of extensive research the pathogenesis remains enigmatic.\nState of research\nIt is known that increased retrograde menstruation caused by uterine dysperistalsis and hyperpersistalsis and subsequent increased oxidative stress on the peritoneal mesothelium are vital factors facilitating the implantation of disseminated endometrial cells and endometriotic lesion formation. The eutopic endometrium in endometriosis patients appears to have a differential protein expression when compared to controls and ectopic endometrial cells of endometriotic lesions exhibit an altered potential for adhesion, invasion and proliferation. The capability for local estrogen biosynthesis and relative progesterone resistance as well as recently demonstrated epigenetic alterations of endometrial cells are key features for the development of this disease. Endometriosis is associated with an immunological dysfunction. Impaired immunosurveillance and peritoneal clearance on the one hand and the proinflammatory microenvironment on the other hand are considered to be key factors for the development of endometriotic lesions.\nPerspectives\nRecent data indicate the relevance of endometrial stem cells in the etiology and pathogenesis of endometriosis. Due to the high proliferative potential, extended cell differentiation capacity and tremendous ability for regeneration, endometrial stem cells are in the focus of research activities.\nSimilar content being viewed by others\nAbbreviations\n- COX-2:\n-\nCyclooxygenase 2\n- PGE2 :\n-\nProstaglandin E2\n- P450arom:\n-\nAromatase\n- StAR:\n-\n„steroidogenic acute regulatory protein“\n- ERα:\n-\nÖstrogenrezeptor α\n- ERβ:\n-\nÖstrogenrezeptor β\nLiteratur\nGuo SW, Wang Y (2006) The prevalence of endometriosis in women with chronic pelvic pain.
