Genetic factors:.Familial clustering of endometriosis is a commonclinical observation.. In families with endometriosis, the disease isoften confined to the maternal line, and is 7 timesmore common in first-degree relatives than in thegeneral populationIn future studies, evaluation of DNApolymorphism may identify specific genesinvolved in the development of endometriosis2003-11-36
2003-11-3 6 Genetic factors： • Familial clustering of endometriosis is a common clinical observation. • In families with endometriosis，the disease is often confined to the maternal line，and is 7 times more common in first-degree relatives than in the general population. • In future studies，evaluation of DNA polymorphism may identify specific genes involved in the development of endometriosis
Immunologic Theory:Lose control of immunologic balanceBoth cellular immunity and humoral immunitychange.1)Macrophage↑ —release IL-1、IL-6、TNF、EGF、FGF etc."→ stimulate T、B lymphocyte proliferationand activation2)Activity ofkiller cell (NK cell and T cell) J3)Produce anti-endometrium antibody4)Abnormal expression of CAMs (cell adhesionmolecules)72003-11-3
2003-11-3 7 Immunologic Theory： • Lose control of immunologic balance • Both cellular immunity and humoral immunity change. 1) Macrophage↑ release IL–1、IL–6、TNF、EGF、 FGF etc. stimulate T、B lymphocyte proliferation and activation 2) Activity of killer cell（NK cell and T cell）↓ 3) Produce anti–endometrium antibody 4) Abnormal expression of CAMs（cell adhesion molecules）
