| abstractText | The dietary intake of selenium (Se) has been shown to influence the development and expression of various biologic processes. This study examined the immunologic competence of lymphocytes from C57BL/6J mice maintained for 8 weeks on Se-deficient (0.02 ppm Se), normal (0.20 ppm Se, as sodium selenite), or Se-supplemented (2.00 ppm Se) Torula yeast-based diets. The ability of the cells to recognize alloantigens, to proliferate in response to stimuli, and to produce interleukin 2 (IL-2) was determined. Se deficiency significantly inhibited the ability of the lymphocytes to proliferate in response to allogeneic stimulation in the mixed lymphocyte reaction or to mitogen stimulation by phytohemagglutinin, whereas Se supplementation significantly enhanced both responses. In contrast, the amounts of IL-2 and interleukin 1 (IL-1) produced by lymphocytes and macrophages, respectively, removed from Se-deficient or Se-supplemented animals did not differ significantly from the amounts of IL-2 and IL-1 produced by cells removed from animals maintained on the control diet. These results suggest that the mechanism(s) responsible for the observed effects of Se on lymphocyte proliferation are independent of the levels of IL-2 or IL-1. |
