N2 - The effect of IFN α-2b on thymidine, uridine, and leucine uptake was examined on peripheral blood mononuclear cells (PBMC) of healthy donors and 15 patients with multiple myeloma (MM). In addition, the surface ultrastructure of the cells incubated without or with IFN α-2b was examined with a scanning electron microscope. The results showed that IFN had no effect on thymidine, uridine, or leucine uptake of unstimulated MM and control PBMC. On the other hand IFN inhibited thymidine, and uridine uptake of PWM-stimulated MM PBMC, but had no effect on healthy donor stimulated PBMC. 1FN inhibited also thymidine and uridine uptake in PHA-stimulated healthy donors and MM patients′ PBMC. The cellular surface ultrastructure of MM lymphocytes incubated with 100 u/ml IFN showed disappearance of the microvilli and formation of cellular pits, whereas in healthy donor lymphocytes IFN caused flattening of microvilli.
