[The role of components of peritoneal fluid in the immunopathogenesis of endometriosis].

Endometriosis is characterised by the presence of abnormally located tissue resembling the endometrium with glands and stroma. The abnormal endometrium of women affected by endometriosis could be able to protect itself from harmful effects of immune cells by expressing specific antigens, by harbouring a different population and by synthesizing and secreting immunosuppressive factors. This disturbance may be regulated by factors in peritoneal fluid which is a specific microenvironment.
