Endometriosis is a chronic inflammatory disease in which immune response and production of estrogen in endometriotic tissues are involved in the development of the disease. Prostaglandin E2 (PGE2) stimulates aromatase (P450arom) expression in endometrioma stromal cells (ESCs) and increases the production of estrogens. On the other hand, an accumulating amount of evidence suggests that IL-4, a typical Th2 cytokine, plays important roles in the disease.
