In work presented at the first germinal center conference, we showed that pregnancy and malignant trophoblastic disease are associated with disappearance of germinal centers from lymph nodes [1, 2]. These findings were discussed in relation to other changes known to occur in the thymus and lymphatic tissue during pregnancy in small mamnals: a reversible atrophy of the thymus [3, 4], reduction in size of lymph nodes as well as a marked reduction in the number of small lymphocytes in lymph nodes, and an absolute lymphopenia in peripheral blood [5]. We also noted the lympholytic effects of adrenal steroids and the thymolytic effect of estrogen and the adrenal steroids [6, 7] and emphasized that these hormones are produced in increased amounts in pregnancy. We pointed out that the foregoing suggests an inhibitory effect of pregnancy on the thymus and lymphatic tissue; the inhibitory effect seemed to be more profound in cases of malignant trophoblastic disease.
