Menstruation protects women from B-cell chronic lymphocytic leukemia
چکیده انگلیسی

B-cell chronic lymphocytic leukemia (B-CLL) affects women and men with different frequency: men show a more than double as high risk to acquire this disease than women. The reason for this sex-related difference is unknown. It is proposed here that menstruation confers advantages to women in two ways: i) early stage B-CLL cells and/or their potential precursors are partially removed from the body with menstrual bleeding which includes shedding of endometrial tissue; and ii) during degradation of the remaining endometrial tissue an immune response against B-CLL is triggered. The regular reduction of potential B-CLL cells throughout pre-menopausal life as well as the immunization against B-CLL would enable the female organism to better control outbreak and course of the disease. Both processes depend on specific binding of the leukemic cells to the endometrial tissue. CD23 expressed on the surface of B-CLL cells is suggested to mediate binding to the vitronectin receptor/CD47 expressed on endometrium. The menstrual inflammatory process includes danger signals that might facilitate initiation of an anti-leukemia immune response. Menstrual immunization might explain sex-related differences in clinical features of other malignancies as well and might therefore have broad implications for the development of individualized therapies.
