3,3'-Diindolylmethane (DIM), a major product of indole-3-carbinol derived from vegetables of the genus Brassica, exhibits chemotherapeutic activity and various immune modulatory effects in animal models and in vitro studies. Although extensive studies have only focused on DIM's beneficial effects, the toxic effects of DIM on the immune systems have not been clearly elucidated. The aim of this study was to explore the immunotoxic effects of DIM in a neonatal mouse and to further evaluate whether DIM administration affects rotavirus (RV)-induced gastroenteritis. Interestingly, multiple immunotoxic effects were observed in the DIM treated group, including decreases in various immune cells (F4/80(+), CD11c(+), CD19(+), and CD3(+) cells) in the spleen, induction of splenic white pulp atrophy, an increase in immune cell apoptosis, and decreased expression of various toll-like receptors (TLRs) in the spleen and small intestine. Apoptosis was notably promoted by up-regulating caspase-3 activity and by the change in the ratio of Bcl-2/Bax activities. Finally, oral administration of DIM led to deterioration of RV-induced intestinal disease and delayed viral clearance in the intestine and MLNs. Our results indicate that oral administration of DIM in neonatal mice induces immunotoxicity and hampers efficient RV clearance in the intestine. This new information about the immunotoxic roles of DIM in a newborn mouse model may provide valuable clues for the development of a safe supplement, especially one designed for human infants.
